Hydraulic system:
1 variable displacement axial piston pump to provide 4 simultaneous, independent working movements and separate pump for slew unit.
Operator aids:
Electronic load indicator with digital readout for hook load, rated load, boom length, boom angle, load radius, analog display to indicate the capacity utilization, limit switches on hoist and lowering motions, pressure-relief and safety holding valves.
Hoist:
Fixed displacement axial piston hydraulic motor, hoist drum with integral planetary gear reducer and spring-applied multi-disk. Drum rotation indicator.
Hydraulic servo control:
Hydro-electric pilot control through self-centering control levers.
Optional equipment
Drive / Steering, 10 x 8 x 8.
