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. When the end wall is in the collapsed condition, further rectangular apertures (36) of the plates (23) are exposed, their spacing and the spacing of the plates being such that a conventional twist lock lifting apparatus can be introduced. The end walls (13) are resiliently biased upright by means which may comprise a torsion bar (44) or a rotatable bar (48) biased against rotation by spring means (54). |
