Rope Crowd with the crowd machinery is located at the front center of the revolving frame, consisting of motor, brake, drum and gearing. Plastic-impregnated crowd and retract ropes are used to move the dipper handle fore and aft.
(Optional) HydraCrowd, hydraulic power skid, located at the front center of the revolving frame deck, powers a large hydraulic cylinder to move the dipper handle fore and aft.
Automatic, single-line system for open gear lubricant and grease
Six pumps (four for open gear lubricant and two for grease) located in an insulated, heated, double-walled lube room
External FastFil from lower level
Upper Works Overall Width - Including Standard Walkways
Ground Bearing Pressure - Note
Ground bearing pressure is dependent upon many factors
A planetary gearbox with dual-output pinions provides the hoist torque transfer from the electric motor to the hoist drum gear.
Dual-motor independent drive
Crawler Dimensions - Overall Width 200.7 cm (79 in) Treads, Standard
Crawler Dimensions - Overall Width 259.1 cm (102 in) Treads
Ground Bearing Pressure - Total Effective Bearing Area (200.7 cm) Treads
