Mitsubishi Caterpillar Forklift America Inc. (MCFA) now offersthe Jungheinrich Warehouse Navigation system technology to the North American market. The system uses transponder Radio Frequency Identification (RFID) technology to control guided Jungheinrich very narrow-aisle lift trucks within the aisles of a warehouse. Transponders are placed in the warehouse floor at specific distances and are used to communicate with a RFID reader/writer in the lift truck to identify warehouse aisle locations and distances. With this information and the forklift’s height measuring capability, the system knows its location within the aisles at all times and can be programmed to reach specific pallet positions by selecting the most efficient combination of traveling and lifting. Integration with the user’s existing warehouse management system (WMS), allows for seamless transmission of orders to the operator’s RF terminal installed on the forklift.
