<p>An elevating platform (1) is attached to the tailgate elevator (2) of an automotive truck by means of a support member (7). The support member is accommodated in a recess (1a) provided in the thick end of the elevating platform and is connected to the elevating platform via the horizontal pivot shaft (6) of the platform, against which shaft a lifting arm (4) co-acting with a lifting cylinder (3) engages. The elevating platform (1) may optionally be freely pivotable relative the support member (7) in which case the elevating platform can be swung to a vertical position by means of an external force, for example a manual force. This upward swinging of the elevating platform can alternatively be effected by means of rocker cylinder device (5, 5a), in which case the elevating platform and support member are joined together by means, for example, of a screw (10). The elevating platform (1) may comprise extruded profiled sections, in which the support member accommodating recess (1a) can be formed by milling. </p> |
