In place of the key switch, a 5 – digit access code enables the operator to work with the vehicle. In this manner only trained co-workers with their appropriate access code can operate the vehicle.

When pedestrians or personnel have unhindered access to the very narrow aisle, it becomes imperative for the vehicle to maintain the safety. Two laser scanners (cat 3) are installed and integrated into the vehicle electronics. The laser scanners are protected by thick walls in the motor compartment (rear sensing) and under the operator cabin (forward sensing). The integration becomes active in the narrow working aisle automatically and scans the zone in front of and behind the vehicle. Should a person or object be detected in the path of the vehicle, the travel speed will be slowed and/or stopped automatically.

RFID or floor magnet zone recognition serves to identify an area and set operating conditions for the vehicle:

• Travel speed reduction (eg. Creep speed or stop)
• Lift cutout – due to low obstructions in the area
• Shift limitation – zone specified due to rack or load size

The advantages for RFID or floor magnet coding, is determined by the number of zones to be identified.

Specific applications may benefit with additional guide rollers:

• Very small distance between the load wheel enclosure and the guide rail
• Interrupted guide rail – an example may be a center aisle opening for pedestrian traffic only
• Very long vehicles

Additional guide rollers typically add to the safety of the overall system, reducing stress on the guide rail and speeding aisle changes.

The speed control unit takes under consideration various floor and load conditions and programs a speed profile suitable for diagonal travel.

Another benefit to this option – numerous height limitations can be programmed.

The height level positioning system is the first step toward warehouse navigation. Simply enter a pre-programmed rack level and the cabin will be raised to the desired height. Advantages are reduced location errors and reduced cycle times. The operator remains responsible for the fine positioning of the forks at the programmed level.

The Height Pre-Selector is the second step in warehouse navigation. This feature takes under consideration the height of the auxiliary mast. Fine positioning becomes dispensable. The Auto Load / Unload Feature enables storage or retrieval at maximum speed.

The warehouse pilot system is the highest navigation level. In manual mode the pilot system will indicate the quickest way to the desired destination. The display indicates how to travel – distance remaining – and the aisle side of the destination. In auto pilot mode the vehicle will travel to the final destination (within the narrow aisle) on its own. There are standardized interfaces towards warehouse management and truck control systems. Retrofittability is guarenteed.
