Abstract
A forwarder has an elongate rigid chassis with a cab at a forward end, a load carrier on the chassis, and a crane serving the load carrier. Four wheels at the front are mounted as a pair on each side, each pair on a common yoke to form a bogie. The bogies can pivot relative to the chassis for up and down movement of the wheels, but the wheels are non-steerable. A single wheel at each side at the rear of chassis is steerable, to provide steering of the forwarder. The cab, the operator, the load lifting device and the load carrier always have the same, fixed, orientation at all times.
