Wester designs and manufactures robust main hoist and long travel gearboxes for cranes up to 100 tonnes, operating at variable speed. We have an in depth understanding of crane hoist gearboxes and their operating environment and through the years have developed an impressive global installed base. Typical main hoist and variable speed drives are characterised by a twin motor input driving dual rope drums through a differential unit.
All gears designed and manufactured to the latest quality standards to ensure reliability and robustness
In house capability to design and manufacture all major components
Custom built designs offering easy maintenance
Innovative non-contact oil sealing system for contra-rotating shafts
Maximum case rigidity ensures constant and accurate gear alignment during operation
Precision gearing designed for even the highest overload capacity. This delivers long gearing life and minimal noise and vibration levels
Complete assurance - split torque designs enable operation at half speed and full load in the event of one motor failure
Easy installation using levelling pads which are set during initial assembly
Service, repair and upgrade of all crane hoist and variable speed drives whatever the make or model
