A device (10) for loading, transporting and unloading cargo (200) including a pair of chassis sides (12, 14), each chassis side including main wheels (110) supporting the device, and a protrusion (150) for engaging with a cargo to be loaded, transported and unloaded, the device further including a link mechanism (36, 38) for expanding and contracting the device by moving the chassis sides (14, 16) towards and away from each other to enable the device to be positioned on either side of a load (200) in an expanded state and subsequently contracted to engage with the load wherein the link mechanism is located above the load in use and is a cruciform linkage comprising two link members (36, 38) of substantially equal length which are pivoted to each other at their respective centres where they cross and which link the chassis sides together, and wherein two transverse wheels (152) are mounted to the rear of each chassis side at the base of the chassis structure for allowing the chassis sides to move laterally when the main wheels are raised above the ground wherein the transverse wheels (152) are arranged such that they are unable to rotate in the same clockwise or anticlockwise direction.
