Bosch Rexroth electric and planetary gear drives are efficient propulsion solutions for hydraulic and electric mobile and off-highway equipment. These planetary gear drives are available as propel, swing, or winch drives. They are best suited for mobile hydrostatic applications, such as propelling drives in tracked vehicles, wheel drives in wheeled vehicles, swing drives for rotary motion, and winch drives for heavy lifting and lowering.

HYDROTRAC GFT Planetary Gear Drive

The Bosch Rexroth HYDROTRAC GFT is perfect for transmission units in high-mileage mobile vehicles, such as bulldozers, agricultural sprayers, heavy-duty vehicles, paves, and rollers. This mechanical planetary gear drive transforms the torque generated by the hydrostatic motor for the wheels and tracks. It features a compact shape, a large selection of gear ratios and drive torques, and a rugged design for long service life.

The perfectly matching gearbox-to-hydraulic motor ratio results in the HYDROTRAC GFT's space-saving design. It combines two three-stage planetary gear drives with a bent axis design axial piston motor to create a compact transmission unit. This Bosch Rexroth planetary gear drive is available off the shelf with a short delivery period.

The Bosch Rexroth MOBILEX GFW is a planetary gear winch drive for challenging mobile and stationary applications. This gear drive is flexible and suitable for drilling rigs, crawler cranes, shipyard cranes, and container cranes. The MOBILEX GFW is sensitive to moving and positioning heavy loads to maximize productivity and create a high safety level for machine operators.

The technical data in each MOBILEX GFW is explicitly designed to meet customer requirements to create the best machine performance. Technical specs may change crane positioning sensitivity and cable speed. Additionally, the excellent rotational characteristics are outstanding for sensitive moving and positioning heavy loads. The GFW winch planetary gear drive features case-hardened gear wheels and tempered surface-hardened ring gears to preserve gear unit service life under harsh operating conditions.
