INTRODUCTIONThe Excel Scaffold Custom/Specialty Manual contains components not found in the Excel Standard Component Technical Manual. This is a supplemental manual to be used in conjunction with the standard manual.

All components found in this manual fall under the same standards and conditions found in the Standard Component Technical Manual.

Some items found in the Custom/Specialty Manual are for sale only, or take additional lead time to manufacture. Please ensure of the availability of components prior to ordering.

This manual does not replace the OSHA 1926/1910 and/or CAL-OSHA documents.

1. Compatibility of Excel Modular Scaffold:

Excel scaffold is designed and engineered to be compatible with standard tube & clamp components (i.e.: clamps, poles, ladders and ladder brackets) that are currently available within the scaffold industry. These tube & clamp components are generally used for:

• Tube & clamp for tie-offs when needed for seismic considerations• When needed to transition horizontally to get around obstacles• When needed to transition vertically to get around interference• Ladders and ladder brackets for access to work platforms• As needed for structural bracing and reinforcement

2. General erection criteria:

Excel was designed and engineered to be constructed using the same requirements specified by OSHA and CAL-OSHA, that have been historically used with tube & clamp and other system type scaffolds.

Excel expects all users to be familiar with all Federal, State and local regulations governing scaffold construction and use.

Excel expects all users to erect, modify or dismantle scaffolding using only qualified and competent personnel with adequate supervision.

Excel expects all users to provide supervision that is competent and qualified, and who can inspect and sign off on each scaffold before authorization is given for general use.

Excel expects all users to follow all common safety guidelines including: pre-job briefings, procedure compliance, tagging, flagging, wearing of proper PPE, weight-loading restrictions, vertical leg placement, use of diagonal bracing, horizontal wraps, proper use of handrails, mid-rails, toe boards, safety netting, screw jacks, ladders, metal or wood decking, etc.

Excel expects all users to utilize a registered professional engineer (licensed PE) to design and approve drawings, as required by OSHA, CAL-OSHA or any other regulatory agency.

3. Special considerations:

Be extra careful when working with components that telescope.

Telescoping components can move/slide while being transported, handled and passed to other workers.

Many Excel scaffold components swivel, slide or hinge. Use caution when passing to other workers, transporting and installing these items.

Ensure that all items containing locks or pins are secured before handling, transporting or passing these items to another worker.

All material must be inspected prior to use! See Section R of the Standard Component Technical Manual for Inspection guidelines.

INTENDED USE OF EXCEL MODULAR SCAFFOLD

1. Unless otherwise stated, all load data presented in this manual includes the OSHA (4:1) Safety Factor.

2. Unless otherwise stated, all load data presented in this manual is for downward or compressive loading only.

3. Excel’s scaffold material, when constructed for normal use, is not designed to be up- or side-loaded in excess of OSHA and ANSI requirements. When conditions require special loading, extra design features must be added to ensure proper stability.

4. Once installed and completed, scaffold should be considered part of the customers plant equipment. Abuse or mistreatment of the scaffold material should not be tolerated.

5. The scaffold material should be inspected for damage and repaired after any incident which could affect the integrity of the scaffold material such as:

• The scaffold comes into contact with any moving equipment, forklifts, trucks or trailers, and other types of mobile equipment.

• The scaffold is affected by an unintended load, flanges or piping attached to a crane or come-along, objects dropped from above or swung in from the side, etc.

• Excessive force is applied to the scaffold from abuse or accidental contact.

• The material is modified in any way with a torch, saw or other equipment.

• The material is affected from corrosive chemicals that remove the coating and/or damage the base metal.

• The material is bent or otherwise damaged.

6. The end-user should ensure that their competent, qualified individuals and scaffold erection personnel are trained and fully understand the above requirements.

7. When testing of material is required, it should be conducted by qualified personnel in a testing environment. Field testing of scaffold components should not be conducted without a formal test plan approved by the manufacturer.

8. All end-users must be trained in the proper use of Excel Modular Scaffold. The tech manual is provided as a reference for training. New users should examine the Key Rules at the end of the manual.

9. OSHA requires that inspections must be made by the scaffold builder and end-user.

BBC2 Big Beam Clamp 2 (3 1/4” Throat) 1,750 1,750 12.0

When building scaffold using Specialty Beam Tube Clamps:1. The clamps should only be used for bracing. They should never be load bearing. 2. Backup clamps should be used where required to prevent slipping.3. Multiple clamps should be used to reduce the loading when building and scaffold. 4. Standard clamps should be used as backup clamps (to prevent slip) when a scaffold is installed in high vibration areas or

for extended periods of time.

Note: 1. All bolts should be inspected regularly before use.2. Clamp bolts tension greatly affects slip loading.3. Clamp bolts should be tightened between 40 and 65 ft-bls. Over tightening could damage the threads, or item the clamp is

attached to. Under tightening could result in clamps slipping at lower than rated loads.

<<< CAUTION There is a pinch point located where the beam sides are located on the clamp.>>>

Specialty Beam Tube Clamps are designed to allow the user to brace scaffold and/or create tie points to beams that have very wide flanges.

The clamps attach to the flange of the I-beam and provide a clamp connection.



EXCEL UNIVERSAL BEAM TUBE CLAMPUniversal Beam Tube Clamps are designed to allow the user to design and build scaffolding in any location where there are accessible approved I-beams.

The clamps attach to the flange of the I-beam and provide either a clamp connection or a two-cup Excel Vertical (VP2).

The clamp and vertical can be rotated in any direction. This allows for a variety of scaffold designs to be built.

When used in conjunction with Adjustable Plank Bearers and standard Excel components, time and material needed can be reduced when building certain scaffolds.

Where a scaffold once needed to be built from the ground, it can now be built from elevated beams or columns.

Safety Notes:1. Guard rail system (GRS) should always be installed and signed-off on by a competent person before pulling any

floor plugs or removing deck grating.2. When installing GRS on roof tops, personal fall protection must be used until the GRS has been completely

installed.3. Leading edge GRS base plates must be set back a minimum of six (6) feet of the opening being protected.4. GRS must be inspected by the craft performing the work prior to each shift to ensure it has not been modified.5. GRS base plates weigh 80 pounds and should be handled by two or more persons, or the proper lifting

equipment.6. GRS should never be used on dirt, gravel or other surfaces that could allow the base plate to sink or slide.


EXCEL MODULAR TROLLEY SYSTEM

The pulley assembly may be placed anywhere on the truss.

The maximum load capacity for a vertical lift is 3,000 lbs.The Trolley system is not designed for side loading and should never be used to pick up any

load not aligned with the trolley.Horizontal members shall be placed at a maximum of every 12 cups (69 inches apart).

Multiple hoists may be used for longer loads, as long as the total weight of 3,000 lbs. is not exceeded, or is designed by an Excel engineer.



The trolley hangs 27 to 29 inches below the top of the truss.

For greater load control multiple I-beams may be grouped on a single truss.

Loads up to 6,000 lbs. can be lifted by two Trolleys under the following conditions:1) The load must be evenly distributed to each

trolley.2) The following Trusses meet the 6,000 lb.

capacity requirement. TR-4, TR-5, TR-8, TR-9, TR10, TR12 See Note 1 for other trusses.

Beam Trolley Splicing allows long runs of beams to be used to move loads greater distances.

Note #1: Loads over 3,000 lbs. can be supported using adequate bracing and beam configuration.Consult an Excel engineer for proper configuration and required bracing prior to installing.Note #2: All beam splices must be within 8 inches of a strap hanger and support truss.Beams may never be spliced in the middle of a run. 3/8 x 1-1/8” grade 5 or stronger bolts shall be used for splicing.

Notes: 1. The trusses supporting the trolley should not be used to support a scaffold board deck.2. The trolley must not be allowed to pass the outermost truss.3. The vertical support for the trusses must be designed to support the required loads.4. All end stops and connector plates must be installed before the trolley is used.5. The trolley beam must be level when installed.6. Do not substituted other components for connectors, end stops, trolley straps, bolts, etc.7. Extra bracing is required when installing a trolley. Bracing should be added to prevent shifting in the direction of

movement.8. Mechanical means shall never be used to move the load.9. Sudden starts and stops must be prevented.

The trolley system should be periodically maintained. If they have grease points, they should be filled with white lithium grease (ST-80 High Performance Grease or equivalent).

Trolleys without grease points should be lubed with a 10 weight oil.

EXCEL MODULAR SRL ADAPTER

The cable supporting SRL or other ladder safety device must be secured to vertical as defined on pages 21 & 22.

The cable must be secured to the vertical 3 cups (between 16 and 18 inches) above the center of the SRL Adapter. The swivel bolt on the SRL adapter must not be over tightened.

The SRL Adapter must be set at the alignment marks, so that the cable supporting the end of the adapter is 1 inch below the center of the adapter.

The SRL adapter is never intended to carry any load. It is designed to align the SRL or other safety device with the ladder access.

As a load is applied to the SRL adapter it will retract bringing the SRL or other ladder safety device and load toward the scaffold and ladder allowing the vertical post to absorb the downward load.

The SRL must be fastened high enough above the ladder so that it is not possible for the person climbing the ladder to come in contact with it.

The SRL adapter is designed to provide support and ladder clearance when using a retractable SRL device to protect workers on the scaffold ladder access.

The SRL or other ladder safety device will drop approximately 4 inches as the SRL adapter retracts.The tension bolts must be torqued to the minimum level required to support the weight of the SRL or other safety device.The SRL adapter clamp or other approved means can be used to attach the SRL cable to the vertical.

EXCEL MODULAR ALUMINUM STAIR SYSTEM

Part Number Description Weight (lbs)

DIS42 Drop in Aluminum Stair Unit 42” Bay 120.0

Stairs can be designed using side brackets or multi-bay scaffolds.

Notes:1. All aluminum stair bays are rated with a light duty rating of 25 psf.2. Excel half clamp braces (part number DSB) or end brace (part number DEB) should be used, with the pins

removed or buttons compressed for stair handrails.3. Aluminum stair bays can be used with SS2 (universal steel stair stringers).4. To transition from a SS2 assembled stair to a DIS42 bay or from a DIS42 to a SS2 assembled stair, a SP36 (36”

metal plank should be used with the SS2).5. Stair systems are to be inspected prior to each shift. This includes treads, risers and hand-rail system. The stairs

should also be tied with #9 wire in heavy wind conditions.

Aluminum stairs are built as a single complete drop in unit. The unit is 34” wide and designed to work with a 42-inch wide bay (using PB42’s as bearers), and used with 7 foot runners (PB84). Completed bay size for the aluminum stair tower will be 7’wide (comprised of (2) 42 inch bays) x 7’ long (using PB84 as runners).

Warning:Improper use of stairs could cause serious injury. Always use handrails and step in the center of the stair treads. Always walk down the stairs, do not run or skip treads. Non-skid adhesive tape may be placed on the edge of the treads for better traction.

Notes:1. The Ladder Cage should always be removed starting from the bottom and worked towards the top to prevent the

swinging of brace components while being dismantled.2. LC3/4 hoops are used as needed to create an opening in the ladder cage for exit to different deck elevation.3. Tube and clamp is used to provide a handrail at the opening and can be adjusted to fit any scaffold design.4. Any combination of horizontals/tube and clamp can be used for the handrail as needed.5. The installer should ensure that when installed the cage extends down the ladder to a point not less than 7 feet

and no more than 8 feet above the base of the ladder and extends a minimum of 42 inches above the top of the landing, unless other acceptable protection is provided.

Excel Modular Ladder Cage Accessories are designed so that ladder cages can be added to most scaffold ladders. The design allows the cage to be installed in compliance with OSHA 1910.27)d)(1).



EXCEL MODULAR RAPID ACCESS SYSTEM

The Excel Rapid Access System (RAS) is designed to provide “stair-like” scaffold access in areas where there is not enough room for a scaffold stair tower.

The RAS system was designed specifically to facilitate getting the worker onto the work platforms safely and quickly.

Notes:1. Workers climb the inside of the scaffold tower, the maximum fall is limited to the deck height.2. The opening is a full 36-inches square, which accommodates the majority of workers and their tools.3. The opening is fully hand-railed around the opening to prevent accidental falls back into access.4. The RAS uses a standard swing gate attached to the horizontal bar for stepping off of the ladder onto the work

deck.5. Allows the insertion of a standard vertical leg (VP8) gate post to the middle of the board deck.6. Telescoping plank bearer (TPB) goes under the long deck boards while allowing attachment of the shorter

deck boards required for the opening.7. The RAS system will easily accommodate construction of tower sizes ranging from 5’ X 6’ and up to 7’ X 10’

without major design changes.8. Workers are no longer required to climb straight up long vertical ladders, or to go over or under mid-rail or top

handrails to get onto the work platform.9. Adjustable hooks allow ladder to remain on thirty degree angle which requires less effort to climb and reduces

slip hazards.10. The RAS system will accept telescoping metal toe boards to secure deck boards to the bearers.11. The RAS was specifically designed so that it could be used with other modular scaffold systems with minor

modifications.12. The RAS does not require any special tools for installation and only a minimal amount of in-service training.13. The RAS is meant to be used only in light-duty application and limited to a maximum loading of not more than 25 psf.14. For scaffolds greater than one work deck high, the RAS entrances must be installed in opposite corners of

the work platform. The RAS is not designed to allow the ladders accesses to be placed on the top of each other in the same corner.




RAS Ladder Hooks are easily installed and are attached over the top of a horizontal to provide support for the ladder.

The RAS-TPB component is adjustable for scaffold widths from five (5) foot to nine (9) foot. It is used to provide support for the board deck and supplies a vertical pin connection that allows a VP8 vertical to be installed for the gate, mid-rail and handrail.

The RAS-HRA component has an Excel End Connector on one end, and a clamp on the other. It is designed to connect a standard vertical to the middle of any horizontal. For the RAS system it is used as the handrail and mid-rail on the back side of the floor opening.

Notes:1. The RAS-SGA Safety Gate Adapter is designed to connect between two horizontals to provide a vertical post

that can be used to attach the safety gate. 2. The swing gate must always open into the work space so that it closes against the VP-8 or vertical when it is

completely closed.3. Tube and clamp may be used instead of the RAS-SGA.

Clamps should be tightened between 40 and 65 ft-lbs. Over tightening could damage the threads, bolt, or item the clamp is attached to. Under tightening could result in clamps slipping at a lower than rated load.

Notes:1. Walk-Through Plates should not be used with scaffolds that will have excessive loading (greater than 25 psf) or

any scaffold over 50 feet high.2. When only one side brace is used the scaffold height should not exceed 30 feet high.3. Netting or other safety material may be required at all scaffold decks, when personal are required to pass under

a scaffold.

The Excel Walk-Through system is designed to provide a walkway under a scaffold. It allows the bottom horizontals to be removed while still providing support for the scaffold base. The flat plate is used to prevent the vertical posts from moving outward and the side brace prevents the scaffold from moving inward.

(SDPB) Short Diagonal Pin Braces or tube & clamp can be used for the side braces. In areas where it is not possible to attach bracing to both verticals it is acceptable to attach the side bracing to only one vertical.

Tying the vertical post to a plant approved structure with two (2) strands of #9 wire or pipe & clamp may also be used in place of side bracing.



DESIGN OF SEISMIC SCAFFOLDING

Design and construction of scaffolding in safety-related areas (near rotating equipment, instrument tubing, trip-sensitive equipment, control panels, regulated areas, etc.) requires additional precautions. These guidelines are not intended to be all-inclusive, and are for those companies, plants, and clients that do not have policies, procedures and conditions already in place for regulated safety-areas and those requiring seismic-designed scaffolding. The clients’s engineering department should be consulted for exact guidelines, procedures, policies and any site-specific requirements the plant may have in place to work in these areas.

The primary concern associated with scaffold installation in safety-related areas involves damage that could be caused to delicate equipment if the scaffold should slide, change shape, collapse or overturn. In order to prevent any scaffold material from coming into contact with safety-related system equipment, the following guidelines should be observed.

The following guidelines are for those clients or plants that do not have existing guidelines, policies and procedures in place for tube and clamp or other system scaffold in regards to seismic scaffolds being built.

1. The scaffold shall be designed to meet all Federal, State, local and plant safety regulations.2. The height of the should not exceed three (3) times the smallest dimension.3. The scaffold should be fastened at the verticals or horizontals with tube and clamp or equivalent to plant

approved structural steel components (i.e. I-beams, handrails, grating, etc.) at the top, middle and base of the scaffold. Diagonal bracing, cantilevered brackets and side brackets must not be used to secure the scaffold.

4. To prevent movement, the scaffold should be secured at two (2) separate locations on opposite corners (see sample bracing diagrams). Scaffolds with more than one bay should be secured at as many outside verticals as possible (see sample multi-bay scaffold diagram).

5. All scaffolds installed near or around safety-related equipment must be secured at as many outside verticals as possible.

6. The scaffold must have an installed board deck or should be braced to prevent the scaffold from changing shape (see sample bracing diagrams).

7. All pins connecting verticals and all horizontals must be securely fastened.8. No unnecessary items or scaffold material should be left unsecured on the scaffold at any time.9. The scaffold should not be left unattended at any time, until it is braced and/or tied adequately and any loose

tools are secured prior to leaving it.10. The scaffold should be provided with screens, mesh or other suitable means to prevent materials from

being dropped on safety-related equipment. Tying-off equipment and tools is acceptable.11. Material or equipment should not be left unattended on any scaffold when the scaffold is not in use. 12. Diagonal braces must be installed on all possible sides. Diagonal braces with Excel trigger end-connectors must

be tie-wired with one (1) strand of #9 wire or equivalent at the ends. When possible, all braces should be wire-tied with one (1) strand of #9 wire or equivalent in the center. Diagonal braces that use 1/2 clamps, and pipe and clamp diagonal bracing, do not require #9 wire at the attachment points.

13. Horizontal wraps should be placed at 3.5 feet intervals.14. A scaffold with wooden parts, including decking, should be free from holes, saw cuts, splits and gaps.15. Decking should be completely placed, with no holes or missing boards, to help maintain a

square and ridged scaffold.



16. All platform decking must be secured (i.e. #9 wire or equivalent means) to the horizontal ledgers that are used for support.

17. The scaffold must be designed to allow access to safety-related equipment at all times.18. The scaffold should be removed immediately upon job completion.19. All Excel scaffold components including ladders, gates, cantilever brackets, side brackets, toe boards,

telescoping braces, etc. can be used when constructing an Excel scaffold structure, as long as those components were installed properly in accordance with the Excel Technical Manual specifications, and also in accordance with the plants existing seismic procedure guideline criteria that are enforced at each facility for erecting staging in safety-related areas.

Notes: 1. The guidelines listed above are for clients and plants that do not have procedures and policies in place.2. In the above guidelines, the words shall and must require that the conditions be followed without variance

as it is written.



Multi-Bay Scaffold (Top View)

Notes:1. All methods of securing may not be available. Allow a minimum of two (2) methods on opposite sides of bracing

at the top, center and the base.2. For scaffolds above fifteen (15) feet in height, bracing should be repeated at seven (7) foot intervals. Individual

plant procedures may vary.3. Use Excel scaffold system connections whenever possible since they do not loosen during a seismic event.4. All clamp connections must be checked for tightness after any seismic event.
