As our first modular planetary gearboxes were developed and built to drive crawler excavators and the first planetary gearboxes with integrated bearings were developed by us, driving construction machinery is a bit of a forte for us. We equip countless construction machines of all types with our travel drives (type T planetary gearboxes), but in recent years we have also developed more complex drive units such as speed change gearboxes for driving drilling machines, plug-in planetary gearboxes for cable winched and milling machine drives.
