CKS600 Kobelco crane - load chart, specs & dimensions (2017 - 2026)

Upper Structure

Torsion-free precision machined upper frame. All components are located clearly and are service-friendly. The engine operates with a low noise level. Counterweight: 13.0 tons.

Weight

Including upper and lower machine, 13.0 ton counterweight and basic boom, hook, and other accessories. Weight: 46.1 ton. Ground pressure: 63.1 kPa.

Clamshell Bucket Lifting

The total load that can be lifted is the value for weight of bucket, slings, and all other load handling accessories deducted from main boom ratings shown. The weight of bucket and materials must not exceed rated load. Optimum bucket should be required according to material. Bucket capacity (m³) x specified gravity of material (ton/m³) + bucket weight (ton) = rated load. Bucket weight must also be decreased according to operating cycle and bucket lowering height. Rated loads are determined by stability and boom strength. During simultaneous operations of boom and swing, rapid acceleration or deceleration must be avoided. Do not attempt to cast the bucket while swinging or diagonal draw-cutting.

Hydraulic System

Main pumps: 3 variable displacement piston pumps. Control: Full-flow hydraulic control system for infinitely variable pressure to all winches, propel and swing. Controls respond instantly to the touch, delivering smooth function operation. Cooling: Oil-to-air heat exchanger (plate-fin type). Filtration: Full-flow and bypass type with replaceable element. Max. relief valve pressure: Load hoist, boom hoist and propel system: 31.9 MPa. Swing system: 27.5 MPa. Control system: 5.4 MPa. Hydraulic Tank Capacity: 440 liters.

Boom Hoisting System

Powered by a hydraulic motor through a planetary reducer. Brake: A spring-set, hydraulically released multiple-disc brake is mounted on the boom hoist motor and operated through a counter-balance valve. Drum Lock: External ratchet for locking drum. Drum: Single drum, grooved for 16mm dia. wire rope. Line Speed: Single line on first drum layer. Hoisting/Lowering: 70 to 2 m/min. Boom hoisting/lowering: 16 mm x 150 m. Boom guy line: 30 mm. Boom backstops: Required for all boom length.

Load Hoisting System

Front and rear drums for load hoist powered by a hydraulic variable plunger motors, driven through planetary reducers. Negative Brake: A spring-set, hydraulically released multiple-disc brake is mounted on the hoist motor and operated through a counter-balance valve. (Positive free fall brake is optional).

Swing System

Swing unit is powered by hydraulic motor driving spur gears through planetary reducer, the swing system provides 360° rotation. Swing parking brakes: A spring-set, hydraulically released multiple-disc brake is mounted on swing motor. Swing circle: Single-row ball bearing with an integral internally cut swing gear. Swing lock: Manually, two position lock for transportation. Swing Speed: 4.5 min⁻¹.

Lower Structure

Steel-welded carbody with axles. Crawler assemblies can be hydraulically extended for wide-track operation or retracted for transportation. Crawler belt tension is maintained by hydraulic jack force on the track-adjusting bearing block. Crawler drive: Independent hydraulic propel drive is built into each crawler side frame. Each drive consists of a hydraulic motor propelling a driving tumbler through a planetary gear box. Hydraulic motor and gear box are built into the crawler side frame within the shoe width. Crawler brakes: Spring-set, hydraulically released parking brakes are built into each propel drive. Steering mechanism: A hydraulic propel system provides both skid steering (driving one track only) and counter-rotating steering (driving each track in opposite directions). Track rollers: Sealed track rollers for maintenance-free operation. Shoe (flat): 760 mm wide each crawler. Max. gradeability: 40%.
