Hydraulic Motors
Track Drive & Wheel Travel Motors
Integrated motor-brake-gearbox final drives for 1 to 110-ton machines
Hydrostatic final drives that combine a two-speed variable-displacement axial piston motor, multi-disc parking brake, planetary gearbox and functional valve block in one unit. Housing-rotating track drives bolt directly into crawler frames and sprockets and deliver 1,396 to 180,000 N·m at up to 35 MPa; wheel versions mount inside the wheel rim. Ratios, displacements and mounting dimensions can be adapted for replacement or new machines.
