Hydraulic motor plus planetary gearbox for winches, slewing, travel and industrial low-speed heavy-duty drives. Stages, ratio, motor, brake and output are chosen by torque, speed and installation.
39 single- and two-stage catalog models; higher torque by two- or three-stage combinations. Output: parallel key, threaded flange, straight-sided spline or internal spline; multi-disc brake optional.
JNM motor with planetary gearbox and an output pinion. Pinion module 4–16; teeth and profile shift designed to the slewing ring.
Two- or three-stage planetary with gearbox, brake and motor in one unit. Torque is rated separately for excavator and crane duty.
Orbital motor with planetary gearbox. Compact, for turntables, small cranes and special machines.
Catalog rated torque is actual output at the stated system pressure, after gearbox efficiency. For shock loads or frequent starts and stops, send peak torque together with radial and axial loads.
Typical uses · slewing and hoisting need different brakes
