Abstract
A power steering device for a self-powered cargo-moving vehicle has a detented steering wheel which can be shifted by the operator to select either a manually operated, power steering mode, a manual override mode in which the guidance device is effectively disconnected and steering is undertaken by a direct mechanical linkage with the vehicle steering column, and, in one embodiment, an automatic, sensor-directed mode in which the vehicle is automatically guided to follow a magnetic wire path.
