ABSTRACT:
A drive station for winning machines and scrape chain conveyors used in mining operations, with main drive and auxiliary drive, and with a measuring and control unit for drive motors and safety slipping clutches. During heavy start and heavy run respectively, a control sensor detects the undershooting of a limit speed of the drive motors, which is preselectable according to a program, and a drive control shifts simultaneously or successively into a slow speed step. Moreover, the drive force of the safety clipping clutches can be adjusted during the starting process.
