BMS800 Kobelco crane - load chart, specs & dimensions (2017 - 2026)

Upper Structure

Torsion-free precision machined upper frame. All components are located clearly and service friendly. Engine will operate with a low noise level. Counterweight: 25.4 ton.

Weight

Including upper and lower machine, 25.4 ton counterweight, basic boom hook, and other accessories. Weight: 76.0 ton. Ground pressure: 85.8 kPa.

Clamshell Bucket Lifting

The total load that can be lifted is the value for the weight of the bucket, slings, and all other load handling accessories deducted from main boom ratings shown.The weight of the bucket and materials must not exceed the rated load.Optimum bucket should be selected according to the material.Bucket capacity (m³) x specified gravity of material (ton/m³) + bucket weight (ton) = rated load.Bucket weight must also be decreased according to the 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.

Power Plant

Model: HINO P11C-VH Type: 4 cycle, water-cooled, vertical in-line 6, direct injection, turbo-charger, intercooler Displacement: 10,520 liters Rated power: 271 kW / 1,850 min⁻¹ Max. Torque: 1,470 N·m / 1,400 min⁻¹ Cooling System: Water-cooled Starter: 24 V- 6 kW Radiator: Corrugated type core, thermostatically controlled Air cleaner: Dry type with replaceable paper element Throttle: Twist grip type hand throttle, electrically actuated Fuel filter: Replaceable paper element Batteries: Two 12 V x 136 Ah/5HR capacity batteries, series connected Fuel tank capacity: 400 liters

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. The 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.

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. The 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): 800 mm wide each crawler. Max. gradeability: 30 %.

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 18mm dia. wire rope. Line Speed: Single line on first drum layer. Hoisting/Lowering: 70 to 3 m/min. Boom hoisting/lowering: 18 m/min x 143 m. Boom guy line: 30 mm. Boom backstops: Required for all boom length.

Swing System

Swing unit is powered by hydraulic motor driving spur gears through planetary reducer. The swing system provides 360° rotation. Swing parking brake: 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, four position lock for transportation. Swing Speed: 4.0 min⁻¹.
