ABSTRACT:
A fully automatic driverless straddle carrier for transporting and stacking freight containers is equipped with several different sensor systems for the vehicle detection and navigation. Laser scanners are arranged at the vehicle for automatically guiding the vehicle over a container stack. In this straddle carrier, one of the absolute sensor systems for the vehicle detection is made up of a local radio detection system, which is arranged on the vehicle as a mobile radio base station, a plurality of radio transponders being stationarily positioned in the traveling area of the working site, an automatic switching device being provided for switching the steering from the automatic steering by navigation to an automatic steering by laser scanners and vice versa, when the vehicle reaches, travels over or leaves a container stack.
