In a preferred embodiment, the at least one swivelling wheel of the second sub-frame and the at least one non-swivelling wheel of the second sub-frame are located on opposing sides of the transverse articulation axis. In a preferred embodiment, the hand trolley is a nesting shopping trolley, and nesting of the trolleys disengages the at least one non-swivelling wheel (36) from a supporting surface such that nested trolleys can be manoeuvred in a lateral direction.
