Swing
Two planetary gearboxes, each driven by a vertically mounted motor, are located on either side of the revolving frame. Dual-output pinion shafts from each gearbox engage the swing rack.
Parallel shaft gear cases, driven by a vertically mounted motor, are located on either side of the revolving frame.
-
Hoist
A planetary gearbox with dual-output pinions provides the hoist torque transfer from the electric motor to the hoist drum gear.
A motor coupled to two gear reductions drives a 137 cm (54 in) hoist drum.
