DRIVES FOR SPHEROIDAL-GRAPHITE CAST-IRON TRAVEL WHEELS The selection tables show pole-changing standard drives for line-fed operation (400 V, 50 Hz) for common speeds. To specify the right drive for your application, proceed as follows: • Determine the total mass to be moved • Select the size, travel wheel type and number of wheels (consider maximum load capacity of individual LRS units) • Determine the drive type: Individual drive or central drive • The total mass is moved by one drive on a four-wheel trolley equipped with a central drive • Half of the total mass is moved by one drive on a four-wheel trolley equipped with individual drives • The drive combinations (11 to 65) for the required travel speed and mass can be seen in the tables.

You can benefit from the entire Demag drive system thanks to its modular design. In addition to offset gearboxes, you can also select angular gearboxes for special mounting situations, for example. Proven Demag KB conical-rotor motors for starting and stopping applications can also be fitted to our gearboxes. Demag sales engineers and our project engineering department will be pleased to help you with these special designs or travel speeds - up to 240 m/min - and masses other than those shown in the tables.
