摘要： A forklift vehicle having front wheels mounted on retractible horizontally extending legs which are normally locked in position, by cylinder operated locking pins, to slide plates on the rear frame of the vehicle. To collapse the vehicle, the fork carriage is rolled forwardly on the front legs; locking pins are hydraulically extended from the fork carriage into the legs while the rear locking pins are hydraulically retracted, and then the mast carriage is retracted retracting the front legs with it. The procedure is reversed to extend the front legs. An operator protective cage and seat extends rearwardly of the rear vehicle frame and can be collapsed upwardly and forwardly, further shortening the vehicle length.
