Travelling gears

High performance in limited space

Bucket wheel excavators and spreaders need to travel to their site of operation on their own. The highest loads occur if a difference in height has to be passed in a cornering. The excavator is moved by single drives that are sufficiently powerful to meet these challenging requirements yet compact enough to comply with the specified space limitation inside the crawler chain.

Depending on the size of the excavator several crawlers and as many gear units are installed. FLENDER worm planetary gear units (type P2CA or P2CF) are standardized application solutions arranged on the top side of the chain.

FLENDER gear units for travelling gears are compact and powerful and equipped with an optimized sealing system for use in extreme operating conditions (dirt, dust, moisture). Extended periods of operation while moving from one location to another can easily be realized. In the standard version, the housing parts of the FLENDER planetary gear units for crawler travelling gear drives are made of steel or of modular or grey cast iron.
