ABSTRACT:
A positioning device for the trolleys of an electric overhead trolley conveyor is described. This positioning device comprises a carrier which is shiftable in the direction of the movement of the trolley. The carrier is connected with a damping device. Further it comprises an engaging member cooperating with the trolley, whereby the engaging member is rendered inoperative toward the end of the carrier movement. This insures on the one side, that the trolley reaches the defined end position by engaging a stopping member. On the other side it is prevented, that the trolley strikes against the stopping member 40 with a high force of inertia. For enabling a recommenced movement the stopping member 40 may be rendered inoperative. The carrier is preferably utilized for this purpose.
