<p>A liftsystem (1) provide with two vertical and parallel placed columns (5), and provide with slides (3), each moved up by a respectively cylinder (10) and connected to said loading platform (2) by a respectively hinge (4), whereby said loading platform (2) can move up from a lower level (18) (groundsurface) upto at least one higher loadingfloor (9), whereby said slides (3) in moving to a down position can leave their respectively column (5) for a part of their length, characterised in which that both slides (3) are rigid attached to each other via a connectionbeam (6) and becomes a rigid frame (7), whereby said connectionbeam (6) is positioned almost equal or in a lower position as the topdeck of said loading platform (2), whereby during the up-and-down movements of said platform (2) said rigid frame (7) gives resistance on canting between said columns (5) in a way that said platform (2 stays almost parallel with the level of said loadingfloor (9).</p> |
