Hydraulic System

Four variable displacement piston pumps are driven by heavyduty pump drive. Two of variable displacement pumps are used in the main hook hoist circuit, auxiliary hook hoist circuit, third hoist circuit and each propel circuit. One of the other two pumps is used in the boom hoist circuit, and the other is used in the swing circuit

 

Control: Full-flow hydraulic control system for infi nitely 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

 

Electrical system: All wiring corded for easy servicing, individual fused branch circuits

Boom hoisting/lowering: 16 parts of 22 mm dia. high strength wire rope

 

Boom guy line: 30 mm

 

Boom backstops: Required for all boom length, Telescopic type with spring bumper

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 multipledisc brake is mounted on the hoist motor and operated through a counter-balance valve. (Positive free fall brake is optional).

 

Drum Lock: External ratchet for locking drum

 

Drums:

 

Front drum:
