Planetary Gearboxes for Mobile Hydraulics
Track, winch, swing and shaft drives for hydraulic motor input
Multi-stage planetary gearboxes built to take a hydraulic motor on the input side, with an integrated wet multi-disc parking brake on most models. Standard versions cover track and wheel drives, in-drum winch drives, swing drives with pinion output and shaft-output units, plus heavy multi-stage gear units that also accept an electric motor. Ratios, flanges and motor adapters can be configured to the machine.
