A device for engaging a load having apertures in a lower portion of the load, adjacent to its base. The device comprises a frame having first and second ends, a load facing surface, first and second jaws supported on said frame and a jaw positioner operable to secure said jaws in a position where they lock the frame to the load with the load facing surface in contact therewith. The frame is connectable to a at least one frame lifter comprising a wheel supported for reciprocating movement between a first position in which, when the lifter is connected to the frame and the frame is connected to the load, the wheel is above a surface under the load, and a second position in which the wheel engages the surface and supports the frame and the load above the surface.
