Planetary plug-in gearboxes are intended for installation in rope winches, and specifically suit customers who require rope winch drums and frames separately, or manufacture them themselves. The standard gearboxes designed for horizontal installation can be adapted for drives powered by both electric and hydraulic motors. The torque is transmitted to the rope drum by the internal gear wheels. As an option, it is possible to produce drive using several hydraulic motors and via a spur wheel gear stage.

Planetary plug-in gearboxes are noted for their compact design and particularly for ease of use and servicing. The integrated main bearing demonstrates high load ratings. Optionally, a connection can be provided for external oil coolers.

Liebherr offers its customer a series-manufactured range of planetary plug-in gearboxes that can be used for a wide range of applications. Tailor-made solutions for specific requirements can also be designed.
