The CKE700 crawler crane from KOBELCO takes advantage of new technologies to raise performance to newheights. Winches with extremely powerful line-pull handle the toughest jobs, while the innovative “wet-type” multi-disc braking system provides safe and sure control with minimal maintenance. A large winchcapacity promotes ultra-smooth operation and enhanced component service life. An optional full-sized thirdwinch enables the use of an impressive selection of attachments. Add these new features to the renownedpower and reliability of KOBELCO cranes, and you have the ideal combination of lifting performance, eco-nomical operation and durability.

For precise and varied operation

Excellent Performance forDiverse Applications

Winch Speed ControllerThe speeds of the mainwinch, auxil iary winch and boom hoist can beset independently withtrimmer controls.

Control Levers Connected Directly to Pilot Valves forSmooth Operation

The control levers regulate the pilotvalves directly to reduce theamount of play and ensure smooth,precise hoisting start-ups and inching. Control is light and sure,with almost no clatter even overlong operating periods.

�Hydraulic pilot systemdetects swing reactionforce.

�Electric throttle with atwist grip ensures sensitive engine control.

�Red switch on the boom lever grip allows easy inching control forhoist, boom hoist, andtravel. The operator canactivate it without takinghis hands off the boomhoist lever.

Versatile OperationThe CKE700 has the power, struc-tural strength, safety specs, andnimble operabil i ty needed toaccommodate all kinds of jobs,from standard crane work to high-rise lifting and material handlingwork.

High-Output EngineThe engine has an impressiverated output of 159kW and com-plies with NRMM (Europe) StageIIIA and US EPA Tier III exhaustemissions regulations. All of thispower works with KOBELCO’sunique Engine Speed Sensing(ESS) control system and newhydraulic systems to ensure stableand smooth simultaneous opera-tions.

Wide, Large-CapacityWinches for Smooth High-Rise Work

The wide hoist winches provide animpressive spooling capacity of 40 m on the first layer with a 22mm hoist rope. Their large capacityand large diameter help to preventuneven spooling and wear whileensuring smooth operation for high-rise work.

Winches with a Powerful Line Pull Handle Hard Workwith Ease

Through the efficient match-up of a high-output engine and high-perform-ance hydraulic motors, the winches deliver plenty of line pull for single-linework. There’s also ample capacity for heavy loads when they first clear theground, and other tough jobs.

Rated Line Pull (Single Line):

111.8 kN (11.4 tf)

Power Lowering and Optional Free-FallA choice of either power loweringmode or free-fall mode can beselected for the winch drumaccording to requirements.

KOBELCO’s new oil cooled wet-type multi-disc brake system isfirst in its class and providesquiet, dependable brakingpower. The multiple discs areself-adjusting and self-equaliz-ing. Forced-oil circulation keepsbrake temperatures cooler dur-ing long, continuous operationsand ensures smooth braking.The completely enclosed sys-tem eliminates the possibility ofoutside contamination, providingyears of problem-free servicelife. In optional free-fall mode,the brake pedal is easilydepressed to reduce operatorfatigue.

Non Free-Fall Winch

Wet-Type Disc Brake System

Large Third Winch (Optional)

Because of KOBELCO’s innovativeinternal disc brake system and sideengine layout, the optional thirdwinch is the same size as the mainand auxiliary winches, allowing formore attachment options and bet-ter operation coordination.

Maintenance-FreeWinches

Both types of winches are mainte-nance-free. The built-in wet-typedisc brake for the free-fall winchhas a forced-oil cooling system toprevent overheating, and requiresno band adjustment or l iningreplacement.

Environmentally FriendlyDesign

Because there’s no brake band,the brake operates quietly anddoesn’t generate lining dust.

Excellent Cab with EnhancedFunctionsMulti-Function LMI Display

The newly designed load moment indicator (LMI)system features a large, easy-to-read LCD display. Therated load, actual load, load ratio, andother information are displayed in largecharacters. Warnings and other items aredisplayed in color, and text messagesand alarms alert the operator to preventdangerous conditions from developing.Other information can also be displayed, including a rated load chartand rated load curve, in addition to afunction that regulates the workingrange.

Multi DisplayThe easy-to-read LCD multi display provides information on the current status of such functions asengine rpm, maintenance, and on-board trouble-shooting, so that the operator has an ongoing, real-time assessment of the machine’s conditions at aglance.

Clear, Panoramic ViewThe CKE700 has a new cabin design with sash-lessfront and top glass that provides a panoramic frontwardand skylight view. The glass also has less curvature tominimize distortion. The front upper window has beenbroadened on both sides for a view that is 31 % widerthan a conventional cab, while the top-window view iswidened toward the rear.

Crawler Retraction to 3.39 m Designed for Easier Transport

With its crawlers retracted, the CKE700 measures just3.39 m wide for easy transport. Total transportationweight (including boom base, gantry and crawlers) is41.2 tons, complying with transport regulations inEurope and helping to reduce the number of trailersrequired.

Boom Assembly/Disassembly ModeThe boom assembly/disassembly mode, which is usedto release the over-hoist prevention function to facilitateboom assembly and disassembly, is activated with aswitch located under the multi-function LCD display ofthe load moment indicator (LMI). (This switch is differ-ent from the switch that releases the auto-stop func-tions for over-load and hook over-hoist.) When theboom is lifted to a certain angle, it is automaticallydeactivated and the LMI function is automatically re-engaged to ensure that the boom assembly/disassem-bly function is used only when needed.

Self-Removal Device KOBELCO has designed theCKE700 to be assembled anddisassembled without the need ofan assist crane by employing acounterweight self-handling sys-tem. The complete crane can betransported on three trucks (eachunder 45 tons) and assembled bythree men in less than half a day.

Conforms with European Exhaust-Gas andNoise RegulationsThe CKE700 meets NRMM Stage IIIA exhaust emis-sions regulations in Europe, and is designed withadvanced KOBELCO low-noise construction tech-nologies to comply with European Noise Regulations.

�External lamp for over-loadalarm notifies surroundingworkers of the load condi-tion.

�Function lock leverhelps prevent acciden-tal operation when theoperator enters orleaves the cab.

�Directional mark-ings on the crawlersmake it easy to seewhich direction thecrawlers will move.

�One-way call sup-ports the safety ofonsite personnel(optional).

Automatic Soft-Stop Function ReducesShocks

This function is activated automatically when boomlowering or boom hoisting is stopped by the over-loadprevention system and the over-hoist prevention sys-tem. It makes for a smooth stop and reduces danger-ous swinging of the load.

Automatic Stop Release Switch with SafetyFunction

The automatic stop system prevents over-load, hookover-hoist and boom over-hoist. To deactivate the sys-tem, a two-stage release pro-cedure is employed that usesa master key and separateswitches. This makes it easyto supervise the use of thesingle key and prevent unau-thorized release of the auto-matic stop system.

Safety Functions of the Optional Free-fall Winch

�Free-fall with Monitoring and Lock FunctionsFree-fall operations can only be initiated by releas-ing the lock using a key switch. Unless the lock isreleased, free-fall cannot occur even if the switch isput in the “neutral-free” position. Also, to prevent thefree-fall mode from being activated accidentallybecause of system malfunction, a monitoring func-tion monitors the free-fall clutch cylinder pressure inthe winch.

�Free-fall Switch with InterlockThe free-fall switches are strategically located onthe hoist levers, allowing the operator to engage

free-fall without removing his handsfrom the control levers. To preventthe load from accidentally dropping,the interlock function makes itimpossible to initiate free-fall unlessthe foot brake is fully depressed.

To prevent the load from accidentally dropping because of operatorerror, do not use free-fall when lifting.
