Abstract: An electric monorail conveyor wherein the vehicles are suspended from and advance along an elongated guide rail. The electric motor of each vehicle receives current from a third rail which is adjacent the guide rail and includes first sections alternating with second sections at locations where the vehicles are to be brought to a halt. The second sections are galvanically separated from the first sections and receive low-frequency current from a frequency converter which can reduce the frequency when the motor of a vehicle is electrically connected with a second section. This renders it possible to arrest the vehicles in predetermined positions with a tolerance of not more than .+-.2 mm.
