1. 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 infinitely variable pressure to front and rear drums, boom hoist brakes and clutches. 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.
  2. 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 item.) Drum lock
  3. Swing unit is powered by hydraulic motor driving spur gears through planetary reducers (2 sets), 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.
