Special gearboxes

Liebherr has always custom-made gearboxes for specific applications. Over time, many drive variations have been developed, for example specialist drives for drilling rigs, stationary concrete mixing plants, chain drives and other designs.

Special gearboxes result from the many possible combinations of planetary stages, spur wheel gear stages and bevel gear stages. The number and size of the driving electric or hydraulic motors vary, and are mostly decided by economic criteria. The gearbox can transmit the output torque via the internal gear wheel as well as via an output pinion, an output shaft, a shaft flange link or other specially designed solutions. Multiple outputs are also possible, such as with the cyclone drive.

The gearbox can be a stand-alone unit or fully integrated into the adjacent structure depending on the application and requirement. In certain circumstances, the components of the adjacent structure can also be included in the order, such as with the drilling drive.
