Movement without limits

摘要

An omni-directional drive system allows material handling vehicles to instantly move in any direction. The Sidewinder fork truck, manufactured by Vehicle Technologies Inc. (Vetex), Trenton, NJ, utilizes uniquely designed wheels for omni-directional movement. Around the circumference of each wheel are spindles canted at an angle, with each spindle containing a pair of rollers. Each wheel is independently controlled; the speed and direction with which each wheel moves determines the trajectory of the vehicle.
