Wheel Offers Omni-Directional Motion Design News

Omni-directional wheel technology by Hammonton, NJ-based Airtrax provides its new lift truck with smooth, crablike moves in any direction. Such translating motion capability offers operators precise movement in tight confines, which allows using more warehouse space for storage by tightening-up open areas needed for truck access. In addition, the truck can carry long loads sideways through narrow overhead doors. The wheel features six elliptically shaped rollers around its circumference. The roller axes are offset by 45 degrees from the plane of the wheel. A wheel is positioned at the four corners of a vehicle, but none are pivoted for steering.
