SECTION I — GENERAL DESCRIPTION

1-1. GENERAL. SHAW-BOX electric hoists are precision builtwire rope and drum type hoists which are made in five ratedload sizes (1/2, 1, 2, 3 and 5 tons) with various lifts, liftingspeeds and electrical service. Equipped with an integrally weldedmounting lug, they are designed to be rigidly attached to anoverhead structure or mounted on SHAW-BOX rigid mounttrolleys for operation on runway beams. On certain modelsoptional base mounting or other supporting methods may beobtained. For full information apply to factory at Muskegon,Michigan 49443.

NOTICE

SHAW-BOX hoists are available with an optional built-inmechanical overload clutch. Hoists having this deviceare identified with words WEIGHT WATCHER on thehoist.

The WEIGHT WATCHER overload clutch permits operation ofyour hoist within its rated load and helps prevent lifting ofexcessive loads which could cause permanent deformation ofa properly maintained hoist or trolley.

1-2. BASIC CONSTRUCTION. All models are of the same basicconstruction and consist of a rugged welded steel frame whichhouses a lifting drum and serves as the suspension for carryingthe entire hoist load. A mounting lug, for attaching the hoist to atrolley or overhead support, is located on top of the frame. Analuminum alloy gearcase and cover, attached to one end offrame, houses a three-reduction gear train and a mechanicalload brake. An electric driving motor with disc-type motor brakeis located beside the frame, face mounted on the back of thegearcase. Electrical system components, located on the end ofthe frame (opposite gearcase end) and enclosed by a steelcover, control operation and rotating direction of a driving motor.A hoisting rope and an enclosed lower block assembly areused for lifting loads. An upper limit stop is used to limit travelof the lower block in the raising direction, to protect hoist fromdamage. A push button control station, for operating the hoist,is suspended from the electrical compartment.

1-3. DIFFERENCES BETWEEN MODELS. The main differencesbetween models are in rope reeving and frame size as describedbelow.

a. Rope Reeving. There are four types of rope reeving used:Two parts of rope single reeved, four parts of rope single reeved,six parts of rope single reeved and two parts of rope doublereeved. Single reeved hoists have one end of the rope anchoredto the drum, whereas, double reeved hoists have both endsanchored to the drum. On single reeved models, the lowerblock travels sideways as rope winds on drum, double reevedmodels offer true vertical lift. For illustrations, refer to Section V,paragraph 5-9, “Rope Reeving” instructions.

b. Frame Size. Length of frame furnished is dependent on hoistcapacity and lift. Four frame lengths are used; short frame, longframe, first and second extensions. Short frame hoists havea rope drum flange to flange distance of approximately 9-3/4",whereas this distance on a long frame hoist is approximately16-3/4". First extension frame hoists have a flange to flangedistance of 22-15/16" and second extensions have 35-3/8".

c. Motor Brake. Hoists are equipped with a disc brake mountedon the motor end bell and operated by a short stroke solenoid.This brake requires periodic adjustment.

SECTION II — INSTALLATION

2-1. GENERAL. SHAW-BOX electric hoists are lubricated andtested before being shipped from the factory. To place hoist inservice, attach to a suitable suspension (paragraph 2-2), connectto electrical service (paragraph 2-3) and perform pre-operationtests and checks (paragraph 2-4).

Design and installation of hoist support shall beperformed only by qualified persons.

WARNING

Steel angles or plates used to suspend hoist should be spacedas close to the hoist suspension lug as possible. Mountingbolts or threaded studs, attaching hoist to mounting structure,shall have a diameter not less than recommended bymanufacturer and material equivalent to ASTM A 325. Makecertain that mounting bolts or studs are long enough so thatthe threads do not engage the mounting support and thatmounting bolts or studs are secured with nuts and lockwashers,self-locking nuts or cross bolting, if unthreaded.

b. Trolley Mounted hoists are attached to moveable trolleys. Ifthe hoist is mounted on an existing trolley, a qualified personshall determine that the trolley and its supporting structure areadequate to support the rated load and weight of the hoist.Hoist/trolley units may be shipped from the factory with trolleypackaged separately. If the trolley can be installed directly overthe end of the supporting beam, assemble trolley to hoist. Becertain that the spacing between wheel flanges, after assembly,is 1/4" greater than exact width of beam flange. (See Figure 2-1below and instruction sheet furnished with trolley.) Using properequipment, carefully lift trolley and hoist and install on end ofbeam.

a. Lug Mounted hoists attach to adequate supports welded orbolted to a building or other structure. The supporting structuremust have sufficient strength with appropriate safety factor, tosupport the weight of the hoist and rated load as well as otherloads to which the supporting structure may be subjected.

DO NOT use small holes for attaching this hoistunless rated load on lower block is 1 (one) ton (2000Ibs.) or less.

WARNING

2-2. SUSPENDING HOIST. The hoist may be suspended in afixed location servicing only the area directly below the hoist(Lug Mounted) or the hoist may be attached to a moveabletrolley or trolleys which in turn may be mounted on an l-beamattached to a building or crane, servicing a larger area (TrolleyMounted).

Before attempting installation of hoist or trolley, themain power switch must be locked in the openposition (off).

WARNING

11207A

2-3. CONNECTING HOIST TO ELECTRICAL SERVICE.Electrical service to the hoist may be power cable or a guardedsystem having sliding shoe collectors

For trolleys which are to be mounted along the span of a beamnot having open ends, measure exact width of beam flangeand assemble trolley to hoist so that spacing between wheelflanges is 1/4" (see Figure 2-1) greater than beam width (3/8" ifbeam has curves). This is accomplished by rearranging thespacer washers on the bolts connecting trolley side plates tohoist mounting lug. If trolley is shipped separate from hoist, seeinstruction sheets furnished with trolley for orientation andinstallation.

When proper spacing has been determined, loosen mountingnuts (item 1, Figure 2-1) to allow trolley wheels to spread farenough to pass over edges of beam flange. (Some installationsmay require complete removal of one trolley side plate.) Usingadequate equipment, carefully lift the hoist and trolley so thewheel treads will rest on the lower beam flange. Replace sideplate and washers if removed for installation. Replacesuspension stud nuts.

Figure 2-1. Sectional View of Trolley showing proper wheel andwasher spacing

a. Follow National, State and Local Electrical Codes whenproviding electrical service to the hoist.

b. Make electrical connections using the appropriate wiringdiagrams furnished with the hoist. All electrical connections,including connections to collectors or power cord, shall bemade only by qualified journeymen electricians.

c. When trolley is shipped separate from hoist, see specialinstructions furnished with trolley for orientation and installation.

2-4. PRE-OPERATION CHECKS

a. Check Oil Level and Grease Fittings. The gearcase has beenfilled with oil to the proper level and grease points for lower andupper sheaves have been lubricated at the factory. However,this should be checked before operating hoist. Check oil levelby removing oil level plug with hoist in a level position. Oil levelshould be at the bottom edge of the plug hole. If not, add oil asspecified in Section IV. Grease fittings in lower and upper sheavepins should show evidence of grease.

Mounting of the hoist/trolley unit on the monorailand final pre-operation inspection shall be performedonly by qualified persons properly supervised.

WARNINGThe green wire provided in the power supply cable(when furnished) is a grounding wire and must beconnected to a proper ground.

WARNING

230/460V single speed motors are reconnectable at themotor. See motor nameplate. Transformer may bereconnected for 200/230/460/575V. See transformer.Check with wiring diagram to make certain that motor,transformer and brake leads are properly connected.

CAUTION

Recheck spacer washers to make certain that the numberof washers between the side plate and hoist suspensionlug are equal, and also the number on the outside of eachside plate are equal. The suspension stud nuts shouldonly be snugged up on the lockwashers until a load hasbeen applied on the hook. A partial load (approx. 25%rated hoist load) placed on the hook will properly seat hoistin the trolley. Tighten suspension stud nuts only after hoisthas been properly seated in the trolley.

CAUTION

Overfilling of the gearcase may result in the excess fluidbeing expelled through the breather.

CAUTION

Be certain that electrical power supply is OFF andlocked in the open position before attempting anyelectrical connections to the hoist. This equipmentmust be effectively grounded according to the NationalElectric Code, or other applicable codes. A separategrounding conductor shall be provided.

WARNING

11403

b. Check Push Button Operation and Phasing.

If any push button binds or sticks in any position —DO NOT TURN POWER ON — determine the causeand correct the malfunction before operating.

WARNING

On three phase hoists it is possible to have “ReversePhasing” causing the lower block to lower when the� button is depressed. When this condition exists,the automatic limit stop switch is inoperative andhoist operation will be dangerous.

WARNING

To properly check the phase of the hoist, follow the stepsbelow:

(1) With “POWER OFF” operate all the push buttons anddetermine that they do not bind or stick in any position.

(2) Temporarily connect hoist to power source.

(3) Operate � button briefly to determine direction of hooktravel.

(4) If hook raises, phase is correct. Turn power off andmake temporary connections permanent.

(5) If hook lowers, hoist is “Reverse Phased”. TURN POWEROFF and correct by interchanging any two leads at powersource connection. Do not change internal wiring ofhoist.

c. Check Limit Switch Operation.

(1) A block operated upper limit stop (Figure 2-2) is furnishedas standard equipment. This limit stop is factory set tostop lower block in its high position and guard againstover-travel and possible damage to hoist. (Note mountingposition of floating lever for 3 and 5 ton hoists.) Noadjustment can be made. Limit switch operation shouldbe tested when hoist is installed. Move hook to a lowposition by depressing push button marked �. Nowdepress button marked � to raise hook. While hook istraveling upward, manually (or with an extension pole)raise limit stop mechanism (Figure 2-2).

Figure 2-2. Limit Stop MechanismBeing Tripped By Lower Block

When floating rod is raised, stop switch is actuated first andthen the reversing switch is actuated (Figure 2-3). Stop switchstops hoist. Reversing switch lowers hook block in case offloating rod over-travel. If limit switch does not function in thismanner, refer to trouble shooting chart Section Vl for possibleremedy.

(2) A screw-type upper and lower limit switch is providedoptionally when both upper and lower limit stops arerequired (Figure 7-2). This switch is adjustable and mustbe adjusted, at time hoist is installed, to desired highand low limits of lower block travel. Refer to Section Vll.

d. Check Lower Block and Hoisting Cable. Depress � pushbutton and run lower block to its lowest position. No less thantwo wraps shall remain on the drum with the loaded hook in itslowest position, unless hoist is equipped with a lower limitswitch in which case no less than one and one half wraps shallremain on the drum. Also check to see that lower block andrope does not twist excessively. If it does twist to the extent thattwo ropes rub against each other, disengage rope from theframe anchor and twist rope four or five turns in a directionopposite to that which the block turns. Reconnect rope to anchor(Figure 2-4), holding firmly to eliminate rope twisting back to itsoriginal position. Operate hoist up and down a few times. Iflower block still rotates, repeat process until twisting is corrected.

e. Lubricate Hoisting Cable. For longer cable life, it isrecommended that the cable be lubricated at time of installationby applying a Chain and Cable Fluid as outlined in Section IV,paragraph 4-3.

Do not attempt to make above test with hook in ahigh position near hoist.

WARNING

Figure 2-4. Rope End Anchor

Safe operation of an overhead hoist is the operator’sresponsibility. Listed below are some basic rules that can makean operator aware of dangerous practices to avoid andprecautions to take for his own safety and the safety of others.Observance of these rules in addition to frequent examinationsand periodic inspection of the equipment may save injury topersonnel and damage to equipment.

a. DO read ANSI B30.16 Safety Standard for OverheadHoists and the Operation, Service and Parts Manual.

b. DO be familiar with hoist operating controls, proceduresand warnings.

c. DO make sure hook travel is in the same direction asshown on controls.

d. DO make sure hoist limit switches function properly.

SECTION III — OPERATION

3-1. GENERAL. Operation of Series 800 SHAW-BOX electrichoists is controlled by a convenient pendant push button station.With it, the hoist can be controlled to give fast lifting and lowering;or controlled to lift or lower load in small increments, providingaccurate spotting. The pushbutton station has a built-in interlockto prevent depressing opposing buttons simultaneously.

When first using hoist, break-in by operating under lighter loadsto full travel before applying maximum load.

3-2. PUSH BUTTON OPERATION

a. Depress push button marked � to raise load.

b. Depress push button marked � to lower load.

c. Jogging the push button will give “hairline” load movement.The quickness of the depressing motion will determine theamount of movement. Excessive use of this “Jogging” featurewill cause premature burning of contact tips and motoroverheating.

d. On two-speed hoists, partial depression of button operatesthe hoist at slow speed; depressing button completely operatesthe hoist at fast speed.

3-3. OVERLOAD CLUTCH OPERATION (Optional). Theoverload clutch, when furnished with the hoist, is factory presetand tested so that the hoist will lift its full rated load but willrefuse to lift overloads which could cause deformation orweakening of your hoist. If the load to be lifted exceeds theclutch setting, the hoist motor will continue to run when the �button is depressed and rotate the load brake gear withoutlifting the load. Whenever this slipping occurs, immediatelyrelease the � button to prevent overheating of the clutch frictionsurfaces and the hoist motor.

NOTICEAlways know load to be lifted. Lift-Tech does notrecommend lifting loads greater than the rated capacityof your hoist.

3-4. OPERATING PRECAUTIONS.

aq. DO operate hoist within recommended duty cycle anddo not “jog’’ unnecessarily.

ar. DO conduct regular visual inspections for signs ofdamage or wear.

as. DO NOT operate hoist with hooks that have opened up.See Figure 5-1.

at. DO provide supporting structure or anchoring meansthat has a load rating at least equal to that of the hoist.

au. DO NOT use hoists in locations that will not allowoperator movement to be free of the load.

av. DO, when starting to lift or pull, move the load a fewinches at which time the hoist should be checked forproper load holding action. The operation shall becontinued only after the operator is assured that thehoist is operating properly.

aw. DO NOT leave a loaded hoist unattended at the end ofa work shift or for extended periods during the workshift. Where operations are such that this conditioncannot be avoided the operator must be assured thatthe condition does not create a hazard to personnel orproperty.

ax. DO NOT use the hoist load limiting device to measurethe load.

ay. DO NOT operate hoist unless hook moves in the samedirection as indicated on the pushbutton. If oppositedirection occurs, see pre-operation checks, Paragraph2-4.b.

az. Observe recommended inspection and maintenanceprocedures.

ba. DO use common sense and best judgement wheneveroperating a hoist. Observe American National StandardSafety standard, ANSI B30.16, Iatest issue.

SECTION IV — LUBRICATION

4-1. GENERAL. The lubrication services outlined in paragraphs4-2 through 4-6 should be performed at regular intervals tomaintain top hoist performance and ensure long life. Intervalsof at least six (6) months, coinciding with spring and fall seasons,

DO NOT operate hoist with the hoisting rope out ofthe drum grooves. Such operation may result in therope breaking and dropping the load which can causedamage to equipment and injury to operator or otherpersonnel. Hoist rope will remain in the drum groovesduring operation under normal operating conditions,however, slack or kinked rope, excessive side pulls,swinging or jerking of load, or similar abuse, maycause the rope to leave the grooves.

WARNING

Figure 4-1. View Showing Location of One Oil Drain Plug

are recommended. The reason for this is, on hoists installedout-of-doors and in unheated areas, a “cold test” lubricant isrequired in cold (below freezing) climates making seasonalchanges necessary.

4-2. CHANGE GEARCASE OIL. (Figure 4-1)

a. Remove oil drain plug from bottom of gearcase and drain outoil. (Two drain plugs, one on front and one on back of gearcase.)

b. Flush out housing using petroleum solvent. Reinstall drainplug.

c. Refill through oil hole cover to proper level (bottom of oil levelplug hole) using 10 pints of Automatic Transmission Fluid,DEXRON III Type, suitable for all temperature ranges.

4-3. LUBRICATE HOISTING CABLE. Hoists are shipped fromthe factory without an exterior coating on hoisting cable. It isrecommended, where conditions permit, that the cable bethoroughly coated at installation and kept well lubricated withLUBRIPLATE Chain and Cable Fluid, or equal, suitable for alltemperature ranges.

4-4. LUBRICATE UPPER SHEAVE AND LOWER BLOCKASSEMBLY.

a. All hoists have grease fittings located in ends of sheave pins.Apply (*) NLGI No. 2 grease for operating temperatures from+50°F to +125°F. For colder temperatures, (-20°F to +50°F) useNLGI No. 1 grease.

b. Apply a few drops of S.A.E. No. 50 oil to hook thrust bearings.(*) National Lubricating Grease Institute.

4-5. LUBRICATE LIMIT STOP LEVER.

a. Apply a few drops of S.A.E. No. 50 oil to pivot points of limitrod.

b. Apply a few drops of S.A.E. No. 50 oil to shaft bearing at rearof electrical compartment.

4-6. LUBRICATE LIMIT SWITCH. Provide a light film of NLGINo. 2 grease on bevel gear of limit switch.

SECTION VINSPECTION AND PREVENTIVE MAINTENANCE

5-1. GENERAL. SHAW-BOX, Series 800, hoists are inspectedand tested at the factory. Regular in service inspection andpreventive maintenance programs not only help reduce overallmaintenance costs but may also prevent serious shutdowns byforewarning of problems that could cause these shutdowns.Regular inspections, periodic minor adjustments, regularcleaning and lubrication and replacement of worn parts canhelp preserve good performance and operation of your hoist.

Many factors influence the inspection and preventivemaintenance program required for your hoist. Frequency andseverity of service and material handled, local environmentalconditions and various applicable codes are some of the factorsthat the user must consider to adjust inspection andmaintenance program outlined in this section to meet his specificconditions.

The inspection and maintenance services outlined in this sectionare considered minimum. Recommended in the schedule areminimum inspection and maintenance intervals based onaverage daily use in a normal environment. Average daily useis based on 1000 operational hours per year maximum andintermittent operation of the hoist eight hours per day, five daysper week with a maximum 40% “on” time and the averageloading not exceeding 65% of rated load.

Environmental conditions in which the hoist operates are alsoimportant considerations for the user when adjusting hoistinspection and maintenance programs to local conditions.Frequency of inspection and maintenance must be increased ifhoist is subjected to severe atmospheric environmentalconditions, such as corrosive vapors, extreme heat or cold,cement or dust and other airborne contaminants. The usershould carefully consider all environmental conditions and adjustfrequency and degree of maintenance for his local conditions.Consult Lift-Tech Field Service Department for advice for unusualenvironmental conditions.

Various codes also regulate inspection and maintenanceprograms. Attention must be given to applicable FederalStandards, OSHA regulations, National Standards, state andlocal codes which may include mandatory rules relating tohoist inspection and maintenance. The user should becomefamiliar with all applicable codes for his area and be guidedaccordingly.

Listed on the Recommended Inspection and MaintenanceSchedule are inspection frequencies and requirements. Performthese inspections regularly as scheduled and additionalinspections as may be required for activity, service andenvironment of your hoist. The hoist operator must beresponsible for determining the operating conditions and severityof service.

Inspection Schedule and Maintenance Report Form.

Shown on page 10 of this manual is a recommended InspectionSchedule and Maintenance Report form which lists variouscomponents of the hoist. The form also includes trolleycomponents, runway components, and miscellaneous items.This form is suggested as a guide for written inspection reports.Inspections are recommended each month and should beperformed thoroughly enough to inform the hoist user ofdeficiencies for any item listed. This form does not supersedethe Inspection and Maintenance Schedule listed below but may

Written, dated and signed inspection reports for many itemsare mandatory under OSHA regulations, and many state safetycodes. It is strongly recommended that the Inspection Scheduleand Maintenance Report, shown herein, be completed by aqualified person designated with the responsibility for hoistoperation and safety or an inspector appointed by this person.

Inspection records can point out the service life of hoistcomponents and help forecast the need for adjustments, repairsand ordering of replacement parts. File and review these reportsafter each inspection.

Deficiencies may be hazardous to personnel andequipment. Do not operate a hoist having deficienciesunless a designated qualified person has determinedthat these deficiencies DO NOT constitute a safetyhazard.

WARNING

5-2. INSPECT LOWER BLOCK

a. Check lubrication of all parts. If the thrust bearing is notequipped with a grease fitting, lubricate with SAE No. 50 oil.Also lubricate the shank of the hook which passes through thelower block body.

Do not operate a hoist having unusual vibrations,sounds or other conditions. Danger may be presentthat the hoist operator cannot see. Determine andcorrect cause of unusual conditions and make certainthe hoist can be operated safely. Be certain todisconnect power to the hoist whenever electricalcover is removed.

WARNING

be used to record scheduled inspection and maintenanceservices required.

The user should revise the inspection interval, add additionalunits or provide a similar form to suit particular conditionswhich may exist. However, written, dated and signed inspectionreports should be maintained particularly on critical items, suchas hoist hooks, hoisting ropes, sheaves, drums and brakes.Periodic review of old inspection reports can point out servicelife of hoist components, forecasting need for adjustment, repairor replacement of these components.

As a matter of expedience, appointed maintenance personnelinspecting the hoist can also take care of minor adjustments,repairs and cleaning, where required. Note the column onInspection Schedule and Maintenance Report form headedCorrective Action and Notes. When corrective action is madeduring inspection, note condition of part or unit as inspected inappropriate Condition column with a check mark (�). Note“during inspection” corrective action taken and date in spaceprovided. In this manner, items requiring further attention willbe checked (�) without showing corrective action. This willadvise the designated person responsible for hoist operationand safety, who reviews the reports, that deficiencies exist. Thedesignated person will check all deficiencies as listed andreexamine or otherwise determine whether they constitute asafety hazard.

f. Reinstall all parts following procedure in reverse ofdisassembly.

5-4. INSPECT ELECTRICAL CONTROLS. Arrangement ofelectrical control equipment varies with the type of control,physical space and the optional control features ordered withthe hoist.

a. Disconnect electrical power to hoist, remove electricalcompartment cover (Figure 9-1, Ref. No. 29) and inspect wiringand terminals. Terminals should be securely crimped to wiresand electrical insulation should be sound. Terminal screwsshould be tight.

b. Check condition of contactor assembly, transformer, and limitstop and reverse switches.

h. Check wear of the hook, especially at the saddle and replaceif badly worn.

5-3. INSPECT UPPER BLOCK AND HOIST SUSPENSION

a. Check upper block sheaves (when hoist is so equipped) forwear, damage and freedom of rotation. If sheaves do not rotatefreely, disassemble block and inspect bearings. Replace wornor damaged bearings, washers, pins or sheaves.

b. Make certain that all sheaves, bearings and hanger pins arefree of foreign material and properly lubricated. Bearings withoutgrease fittings are lubricated for the life of the bearing andrequire no further lubrication. After inspection, lubricate all upperblock lubrication fittings.

c. Make certain that rope guide pins are not bent, loose orotherwise distorted; guide pins must have close clearance tosheave flange to keep rope in sheave grooves.

Figure 5-1. Proper Hook Opening(shown with latch removed for clarity)

Do not operate a hoist having worn or damagedsuspension bolts.

WARNING

b. Check each sheave to ensure rope groove is smooth andfree from burrs, or other surface defects.

c. Check each sheave for freedom of rotation; replace bearingsif defective.

d. Make certain that dowel pin, holding the hook nut to thehook, is securely in position.

e. If hook is equipped with a safety latch or rotational lock,check to determine that they are in good operating condition.

f. Check throat opening of hook. (Refer to Figure 5-1.) It isrecommended that upon receipt of the hoist a measurement bemade and recorded of the hook throat opening. OSHA Standardsrequire that the hook be replaced if the throat opening exceeds15 percent of the original opening, or if the hook is twistedmore than 10 degrees from the unbent plane. A gage block,properly identified to the hoist, similar to the one shown inFigure 5-1, is suggested to be made for each hook for use inthese measurements.

Note: Hooks and hook openings shown are based onhooks normally furnished with standard hoists. Fordimensions of hooks having a special size, shape ormaterial, consult the Muskegon, Michigan factory. Forhooks with certain kinds of safety latches it may benecessary to remove latch to measure hook opening.

g. Hooks showing signs of cracks must be replaced. Hooksshould be inspected at least once per year using dye penetrants,magnetic particle or other suitable crack detecting methods.

d. Check hoist suspension bolts on lug suspended hoists; makecertain that bolts are secure, properly tightened and free fromdamage.

e. Inspect suspension lug at top of hoist frame for damage,cracks, hole elongation or other signs of wear. On all hoists, thesuspension lug is integral with hoist frame and the entire framemust be replaced when suspension lug is damaged and requiresreplacement.

5-8. ROPE INSPECTION, MAINTENANCE ANDREPLACEMENT

Figure 5-11. Removing Bolt Securing Gearcase to Frame

a. Inspection. Wire rope on your hoist is one of the mostimportant components requiring frequent inspection andmaintenance. All wire ropes will eventually deteriorate to apoint where they are not safe and will require replacement.

WIRE ROPE SHOULD BE THOROUGHLY INSPECTED ATREGULAR MONTHLY INTERVALS BY AN AUTHORIZEDPERSON AND A DETERMINATION MADE WHEN FURTHERUSE OF THE ROPE WOULD CONSTITUTE A SAFETYHAZARD. Each inspection should include a written, dated andsigned report of rope condition. Reports should be filed andreviewed each month and any rope deterioration carefully noted.

Wire rope improperly handled or abused can createa SAFETY HAZARD. Read and comply with inspection,maintenance and replacement information givenherein.

WARNING When first using the hoist after rope replacement, break-inrope by operating under lighter loads to full travel before applyingmaximum load.

5-9. ROPE REEVING

a. General. Before unreeling rope from a coil or reel, be surefloor is clean. Dirt picked up by the rope can cause excessivewear and abrasion. Uncoil the rope by rolling the coil or reelalong the floor; or, place reel on a stand with a shaft throughthe center of reel so rope can be pulled straight out with thereel rotating.

Use only factory approved rope with swagged wirerope sockets.

WARNING

adjusting nut are tight. DO NOT TURN ADJUSTING NUT ORDISASSEMBLE CLUTCH. If spring washer, adjusting nut orgear is loose or damaged, or the clutch did not function properlybefore disassembly of hoist for inspection, consult the nearestSHAW-BOX Authorized Repair Station for repair or adjustment.

5-7. INSPECT ROPE DRUM AND SHAFT

a. To remove drum, remove wire rope, electrical compartmentcover and electrical panel assembly (Figure 9-1) and gearingand load brake assembly (paragraph 5-6).

b. Remove four hex socket head bolts securing gearcase tocover. Three bolts are accessible from inside frame (Figure 2-2,Section II) and the fourth is accessible from electrical end offrame through special access hole using a socket hex keywrench with an extension (Figure 5-11). With bolts removed,pry assembled gearcase and motor from frame. Exercise cautionso that gearcase and motor assembly does not fall as it comesfree of frame. This disassembly operation is not recommendedwith hoist suspended. Drum will remain in frame and can belifted from drum shaft. To remove shaft, remove internal retainingring from bearing bore in frame.

Inspections revealing rope deterioration, including, but not limitedto the following conditions should cause the inspector to questionremaining strength of rope and consider replacement:

(1) Twelve randomly distributed broken wires in one ropelay or four broken wires in one strand.

(2) Wear of one-third of the original diameter of outsideindividual wires.

(3) Kinking, crushing or bird caging.

(4) Heat damage from any cause.

(5) Reductions from nominal diameter of more than1/64" for 3/16", 1/4", and 5/16" diameter rope.

(6) Rope corrosion, internal or external.

(7) Effects from improper lubrication.

(8) Rope idle for month or more due to shutdown.

Special attention should be exercised when inspecting ropenormally hidden during inspecting procedures.

b. Maintenance. Keep rope well lubricated to help reduce internalfriction and prevent corrosion. Lubricant, as described inparagraph 4-3, should be applied as a part of the regularmaintenance program. Special attention is required to lubricatesections of rope over equalizing sheaves and other hiddenareas.

Avoid dragging ropes in dirt or around sharp objects which willscrape, nick, crush or induce sharp bends in the rope.

c. Replacement. When recommended by an authorizedinspector, the rope should be replaced. Replacement ropeassemblies are shipped from the factory carefully coiled toprevent damage by kinking. Care must be taken to avoid twistingor kinking when uncoiling and handling during reeving.

Before replacing rope, check condition of grooves in sheavesand drums to determine if they are excessively worn.

It is imperative that the rope reel or coil rotates as ropeunwinds. If coil or reel does not rotate, the wire will betwisted as it is uncoiled and kinking will result. A kinkedrope may be damaged and unsafe for maximum service.

5-10.TESTING HOIST AND OVERLOAD CLUTCH (optional)

a. General. Before placing hoist in service or after disassemblyand reassembly, hoist should be tested. To test suspend hoistfrom an overhead supporting member of sufficient strength tosupport the weight of the hoist and the rated load. Hoists hav-ing overload clutches, require an overhead supporting struc-ture capable of supporting with appropriate safety factor, a loadequal to 200 percent rated load and the weight of the hoist.Connect hoist to power supply as shown on hoist nameplateand perform the checks listed in b and c below.

b. Check hoist as outlined in PRE-OPERATION CHECKS,Section II, paragraph 2-4.

c. Check hoist with capacity load.

(1) Attach rated load to lower hook.

(2) Depress � push button and raise load. When pushbutton is released, hoist should immediately stop andhold load at that level.

(3) Depress � push button, lower load a short distanceand release button. Hoist should stop immediately andhold load at that level.

Note: If load drifts downward slowly in step 2 or 3 above,motor brake requires adjustment - see MOTOR BRAKEADJUSTMENT - Section Vll - paragraph 7-2.

(4) Insert lower sheave pin into bottom block removing pipeas sheave pin is inserted. Be certain washers arereplaced as shown on parts illustration. With sheave pininstalled, replace key plates and bolts to secure sheavepin.


(6) Lubricate rope per paragraph 4-3.

h. Checking for and removal of rope twisting.

Although rereeving of hoist may have been done carefully,sometimes after new rope has been installed twisting mayoccur. With new rope installed, the hoist block should be raisedand lowered several times with gradually increasing loads,through full lift. If the block still rotates excessively at no load,the rope may have twists which should be removed.

d. Overload Clutch. The overload clutch (optional) must betested for proper operation before placing hoist in service orafter disassembly and reassembly of hoist. For test procedurefollow instructions listed below.

Do not lift more than rated load except for testpurposes.

WARNING

To prevent overheating, release the hoist controlbutton at once when the hoist refuses to lift the load.

CAUTIONBEFORE ATTEMPTING TO TEST THE OVERLOADCLUTCH, MAKE CERTAIN THE FOLLOWINGPREREQUISITES ARE STRICTLY OBSERVED:

a. An appointed person must determine, beforestarting, that all structures supporting the hoist areadequately strong to withstand the test load of 200%of the rated load, plus the weight of the hoist, whetherhoist is tested in installed position or moved to adesignated test facility.

b. Loads used for testing must be accurately known.

c. Test must be made ONLY by a qualified operator,thoroughly familiar with the hoist and the purpose ofthe test.

d. Adequate and proper rigging must be provided toensure that test loads are securely attached, properlybalanced, and lifted level. Failure to provide adequatesupport could cause injury to personnel and/ordamage to equipment.

WARNING

(1) Using a known load, equal to the hoist rated load,energize hoist to lift the load. Raise this load just highenough to be certain hoist is lifting the entire load. Clutchshould not slip with the rated load. Lower load to restposition. If clutch slips with rated load, adjustment isrequired. (See paragraph 7-5. - “OVERLOAD CLUTCHADJUSTMENT”.) If hoist will lift rated load, proceed tostep (2).

(2) Increase load in steps from rated load, TO A MAXIMUMOF 200% of the rated load, attempting to lift load witheach increase in weight. Hoist Overload Clutch shouldslip and refuse to lift load before 200% of the rated loadis reached. Should hoist lift 200% of the rated load -STOP TEST - A CLUTCH ADJUSTMENT IS REQUIRED.(See paragraph 7-5 - “OVERLOAD CLUTCHADJUSTMENT”.)

(3) Run hoist with load causing clutch to slip (hoist refusingload) five cycles of approximately 1 second each.

(4) Remove weights added in step (2) and return to hoistrated load. Lift rated load one final time. Clutch shouldnot slip.

Notice

ALWAYS KNOW LOAD TO BE LIFTED, LIFT-TECH DOESNOT RECOMMEND LIFTING LOADS GREATER THANTHE RATED LOAD OF YOUR HOIST.

7-1. MECHANICAL LOAD BRAKE. The mechanical load brakeon Series 800 SHAW-BOX hoists is a pawl and ratchet “Weston”type automatic brake. The brake is not adjustable and requiresonly periodic inspection and occasional replacement of thefriction washers.

7-2. MOTOR BRAKE. Check brake adjustment after first 30days of service and regularly thereafter during the six-monthinspection procedure.

Installation and Service Instructions for 54,000 Series(rev. A) Manual Adjust Brakes.

Important - Please read these instructions carefully beforeinstalling, operating, or servicing. Failure to comply with theseinstructions could cause injury to personnel and/or damage toproperty if the brake is installed or operated incorrectly.

Caution1. Installation and servicing must be made in compliance withall local safety codes including Occupational Safety and HealthAct (OSHA). All wiring and electrical connections must complywith the National Electric Code (NEC) and local electric codesin effect.

2. To prevent an electrical hazard, disconnect power sourcebefore working on the brake. Lock disconnect in the off positionand tag to prevent accidental application of power.

3. Be certain power source conforms to the requirementsspecified on the brake nameplate.

4. Be careful when touching the exterior of an operating brake.Allow sufficient time for brake to cool before disassembly.Surfaces may be hot enough to be painful or cause injury.

5. Do not operate brake with housing removed. All movingparts should be guarded.

6. After usage, the brake interior will contain burnt and degradedfriction material dust. This dust must be removed beforeservicing or adjusting the brake.

DO NOT BLOW OFF DUST using an air hose. It is important toavoid dispersing dust into the air or inhaling it, as this may bedangerous to your health.

a) Wear a filtered mask or a respirator while removing dustfrom the inside of a brake.

b) Use a vacuum cleaner or a soft brush to remove dust fromthe brake. When brushing, avoid causing the dust to becomeairborne. Collect the dust in a container, such as a bag,which can be sealed off.

General Description - This series brake is spring set,electrically released. These brakes will contain one or twofriction discs driven by a hub mounted on the motor.

Operating Principle - When the brake coil is energized thelever arm retracts the spring force from the disc pack, allowingthe friction disc to rotate with the hub and motor shaft. Whenpower is removed the lever arm pushes down on the stationarydisc and friction discs. The hub is held from rotating, and theload is held in place.

Do not release brake if there is a suspended load onthe hoist hook.Manually releasing the brake may allow a suspendedload to fall, possibly causing damage, injury or death.Always be certain any suspended load (which includesbelow the hook devices or attachments) are removedbefore servicing, adjusting or removing brake.

WARNING

Apply Loctite 680 to set screws.Tighten set screws on motor shaft.

Place hub on motor shaft.� �

Align friction disc with splined hub and slidebrake against motor face.

�

Connect coil leadwires to power supply. Referto nameplate for voltage rating.*Caution: Keep wiring away from pinch pointsand moving components.

Air Gap Adjustment

Brake air gaps are factory adjusted to .100”. As friction discswear the air gap will increase. When the gap reaches .200” itwill need to be readjusted to .100”.

1. Loosen jam nut (10N).

2. Turn adjusting screw (10) CW until .100” gap is reached(see Fig. 1).

3. Retighten jamb nut.

4. Check air gap again...

Torque Adjustment

The brake is factory set for nominal rated torque. No furtheradjustment to increase torque may be made. The approximatecompressed torque spring height is shown below. Torquereduction may not exceed 1 full turn in the CCW direction.Note that the spring measurement for the 6 and 9 lb-ft springis from inside the shoulder washer.

7-3. BLOCK OPERATED LIMIT SWITCH. The block operatedupper limit stop, furnished as standard equipment, isnonadjustable and designed to stop lower block at its highpoint of travel to guard against over-travel with possible damageto hoist. When high point is reached, limit stop switchautomatically stops hook travel. If hook drifts upward slightlyafter stop switch is actuated, a reversing switch will close andautomatically reverse direction of hook travel.

7-4. SCREW-TYPE LIMIT SWITCH. This limit switch has arotary screw driven by a gear reduction which is coupled to theend of the drum shaft. Adjustment discs operate the contacts ofseparate switches; one for the hoisting circuit and one for thelowering circuit. The switch assembly must be wired inaccordance with the appropriate wiring diagram, which ispackaged with hoist. Adjustment of this screw-type limit switchis accomplished as follows: (Refer to Figure 7-2).

Before attempting actual adjustments, be certain mainpower switch is OFF and locked in the open position.

WARNING

a. Remove four screws and lift off switch cover.

b. Loosen locking plate screws. Slide locking plate away fromadjustment discs.

c. Turn proper adjustment disc (right for up, left for down) towardstitch to reduce hook travel or away from switch to increasehook travel.

d. Slide locking plate back into position ensuring slots onadjustment discs are fully engaged, tighten locking plate screwsto 4 in-lbs.

e. Replace cover.

Figure 7-2. Screw-Type Limit Switch Adjustment(Wires not Shown for Clarity.)

Check limit switch operation carefully, without load,before placing hoist in service. If misadjusted,SEVERE DAMAGE AND/OR A DROPPED LOADCOULD RESULT. Allow 6" for hook drift in bothdirections. Never allow less than 1-1/2 complete wrapsof rope on drum with hook in lowest position.

WARNING

Provide a light film of NLGI No. 2 grease on bevel gear of limitswitch.

7-5. OVERLOAD CLUTCH ADJUSTMENT. When properlyadjusted, the overload device is designed so that the hoist willlift its full rated load but will refuse to lift an excessive overload.The overload clutch is not externally adjustable. It is necessaryto remove the overload clutch assembly from the hoist for properadjustment. Therefore, it is strongly recommended that whenadjustment and/or replacement parts are required, a SHAW-BOX Authorized Repair Station be contacted. Consult yourSHAW-BOX Distributor for nearest Repair Station.
