Abstract
An apparatus for moving ropeway vehicles in a ropeway system includes at least one conveying wheel being adjustable in height relative to the vehicles by a lifting device to be brought into abutment against the vehicles for displacing the vehicles along a track using the conveying wheel. An electric lifting device has an electric drive motor with a threaded sleeve or the like to be retained in its height position and rotated by the drive motor and a lifting spindle to be adjusted in height by the threaded sleeve for adjusting the conveying wheel in height. Upper and lower end surfaces of the threaded sleeve and the lifting spindle have stops located approximately in planes normal to the direction of rotation of the threaded sleeve or the like which, in upper and lower end positions of the lifting spindle, abut one another preventing further rotation of the threaded sleeve.
