The hoist is the core component of every crane. A motor which is connected to a gearbox drives the drum to allow the lifting and lowering of loads.

Trolleys drive along the crane bridge and serve as a chassis for one or several hoists.

Motor, gearbox, and wheel form a compact unit. These drive units are used for the horizontal movement of crane bridges, trolleys and slewing jibs and for all applications where the motorised moving of heavy items is required.
