Wire Guidance

A small groove (typically 1/8" wide x 3/8" deep) is cut down the middle of the working aisle. A signal generator (line driver) sends a frequency through the wire at a very low DC voltage. The vehicles guidance system is tuned to this frequency and can automatically sense and steer the vehicle along the guide path in both travel directions. The vehicle velocity is automatically reduced during the acquisition of the wire path. Once locked ON to the guide signal, travel resumes at normal velocity.

Features include the ability to maintain a clean warehouse without floor mounted rails, however primarily guide wire does not require the use of a lower rack beam. Loads may be placed directly on the floor.
