Abstract: A load carrying platform (10) having a pair of end walls (13) movable between an upright condition in which the end walls (13) and platform (10) define a container for transporting goods, and a collapsed condition in which the end walls (13) lie parallel to and closely adjacent the platform (10). Each end wall (13) includes a pair of corner posts which are individually pivoted to pivots (22) provided between rigid plates (23) mounted at the corners of the platform. The base of the corner post (15) is L-shaped, the pivot (22) being received in an arm (21) of the L-shape and being spaced from the end of the platform (10) so that rotation of the corner post (15) displaces it from its position between the plates (23). The cam locking bar is inserted through generally aligned openings (26,27) in the post (15) and plates (23), the locking member having cams which can be urged into locking engagement with the openings by rotation of the member (28) to lock the end wall upright.
