A device for lifting and moving a load having apertures in a lower portion of the load. The device comprises a frame having first and second ends and a load facing surface. First and second jaws are supported on the frame and the jaws are receivable in the apertures of a load. A jaw positioner is provided for moving the jaws towards or away from each other to a position where they lock the frame of the device to the load with the load facing surface in contact with the load. The device further comprises a first frame lifter and a connector for connecting it to the first end of the frame, and a second frame lifter and a connector for connecting it to the second end of the frame. The frame lifters comprise a wheel supported for reciprocating movement between a first position in which, when the frame lifter is connected to the frame and the frame is locked 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.
