Abstract
A pallet jack includes forks which can be removably attached to the base for positioning in a horizontal use position or a vertical storage position. The base includes forwardly open sockets for receiving the forks in the use position and upwardly open sockets for receiving the forks in the storage position. A lock mechanism locks the wheels in the use position. In an alternative embodiment, the base is eliminated, with each fork having an actuator for raising and lowering the fork wheels.
