ABSTRACT:
A control system for a materials-handling device, especially for a shelf storage and retrieval device. The device includes a horizontal travelling mechanism having a horizontal drive; a lift truck which can be raised and lowered on a mast via a lifting drive; and a storage/retrieval drive for storage and/or retrieval of the goods to be handled. The present system provides a simplified assembly and a design with respect to the supply of current. The simplified assembly and design is accompanied by supplying the electrical power for the storage/retrieval drive and for data transmission with a signal converter through the use of contact conductors arranged on the mast and the power is picked up from the contact conductors by sliding contacts on the lift truck.
