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. The first sections of the third rail are connected with a source of higher-frequency current, and a follower of each vehicle is electrically connected with the third rail as well as with the respective motor so that an arrested vehicle can be rapidly accelerated from zero speed to full speed while it receives current from a first section of the third rail by way of the corresponding follower.
