China OEM Planetary Gearbox for Dock Cranes near me manufacturer

Planetary winch gearboxes are suitable for various winch applications due to their wide torque range. The compact design allows the gearbox to be integrated into the winch drum. The fail-safe brake can be integrated inside the gearbox or mounted externally; the gears are lubricated together. Electric versions are available in in-line and right-angle configurations. Torque ratings are organized by grade and are in accordance with the gear’s minimum approved grade safety factor.
We design and manufacture custom winches to fully meet each individual application requirement.
Hydraulic traction winches have individually selected drums, gearboxes, motors, and valves according to the winch series. The result is a traction winch that guarantees the highest level of efficiency and reliability.
The motor of the winch is coaxial with the drum and can be equipped with a disengagement device.
A variety of accessories are available to complete the product: wire ropes, pulley blocks, hooks, tensioners, and fairlead roller guides.
