ABSTRACT:
A self propelled forklift vehicle having a frame formed by two spaced parallel longitudinal frame members and a rear transverse frame member. The fork carriage is movable forwardly and rearwardly on the longitudinal frame members, along the path of the machine, and carries a fork tower and forks. The forks can be forced below the vehicle to raise the vehicle up beneath the rear of a trailer for transport. The vehicle's rear wheels, which steer and drive the vehicle, are closely spaced and tiltable from side to side to allow for rough terrain, with the operator seat and motor on opposite sides thereof to balance each other. A manually operated split pulley drive allows creeping of the vehicle at a closely controlled low speed. The fork tines include erectable rollers to support part of the vehicle weight when the forks carry a forwardly extended load, to prevent tipping. A front gate causes discharge of the contents of a pallet onto the ground when the fork carriage is retracted. An automatic centering mechanism returns the rear driving wheels to either front driving or rear driving position as selected by the operator.
