Our Demag travel units are used for rail-guided travel applications in the heavy load range. A complete travel unit consists of a non-driven RNE wheel set and a driven RAE wheel set. Demag offset geared motors are used as drive units. The use of these proven series-manufactured components offers a high level of functional reliability and guarantees interchangeability when the wheel is replaced.
 
Sizes can be supplied with travel wheel diameters of 400, 500 and 630 mm with load capacities from 28 tons to 60 tons.
 
Applications
You can use Demag RAE/RNE wheel sets for a wide variety of applications. You can not only use them in the cranes and materials handling sector, but also in related mechanical engineering solutions. The wheel sets can be installed in hollow profile sections, box girder sections and as corner bearing units.
