SYSTEM OCH ANORDNING FOR ETT PALASTANDE OCH AVLASTANDE FORDON

摘要

An automatic control system for a vehicle such as a fork lift truck automates the transportation, loading and unloading operations of the vehicle in a work area. Leader cables disposed in the work area are supplied with instruction signals of respectively different frequencies from terminal units in response to commands from a central control device. Any cable or a combination of two cables forms a ehicle guideway along which the travel of the vehicle is controlled by instruction signal pickup coils on the vehicle and along which loading and unloading stations for the vehicle are located. Loading and unloading are effected without using the leader cables, the necessary instruction signals then being received from the central control device by the vehicle from a coil disposed at the loading and unloading station.
