The invention relates to a transport vehicle for transporting at least one transport unit. The transport vehicle including at least one drive unit having at least one electric drive, at least one steerable vehicle wheel, at least one standing platform, at least one control unit (6), and at least one loading fork, and at least two longitudinal outriggers, which are arranged parallel to one another and at a distance from one another and extend in a longitudinal direction of the transport vehicle and between which the loading fork is arranged so as to be height-adjustable and which are in each case connected to the drive unit by one end section and at the respective other end section of which in each case at least one non-steerable vehicle wheel is arranged.

The present invention relates to a removable electric propulsion system (1) for a rolling object. Propulsion system (1) comprises a frame (2) with a driven wheel (3) and at least one non-driven wheel (4). Among these non-driven wheels (4), one at least is an orientable off-centered wheel. System (1) also comprises means for coupling at least one wheel of the rolling object. System (1) also comprises an automatic directional locking device for locking the rotation about a vertical axis of at least one of the orientable off-centered wheels in a predetermined direction.

The invention also relates to a coupled assembly comprising a propulsion system (1) and a rolling object.

The invention further relates to a method for directional and automatic locking of at least one orientable off-centered wheel of a propulsion system.

A pallet jack includes a base and a pair of tines extending from the base. The pair of tines including a first tine and a second tine. A load wheel supports an outer end of each of the pair of tines. Each load wheel is configured to move toward and away from the respective tine to raise the tine off a floor on which the load wheel is supported. The first tine including a support surface configured to selectively be a lowermost surface of the tine to facilitate lateral displacement of the first tine.

The present application discloses a pallet truck backrest assembly for handling half-size pallets. A first half-size pallet support is pivotally coupled to a backrest of the backrest assembly at a first height and a second half-size pallet support is pivotally coupled to the backrest at a second height with the second height being less than the first height. The half-size pallet supports pivot between first positions against the backrest and second positions extending over the forks of the pallet truck to accommodate half-size pallets.
