Abstract (en)

A scissor lift device, for example for a working platform, the scissor mechanism of which possesses, for one scissor axle 4 only two scissor arms a and b connected to one another so as to be pivotable about this scissor axle. The torsional moments thereby occurring in the scissor arms cause prestresses in the bearings of the scissor axle and make the scissor mechanism free of play. <IMAGE>

Abstract (de)

Eine Scherenhubvorrichtung z.B. für eine Arbeitsbühne, deren Scherengetriebe für eine Scherenachse 4 nur zwei um diese Scherenachse schwenkbar miteinander verbundene Scherenarme a und b aufweist. Die dabei entstehenden Torsionsmomente in den Scherenarmen verursachen Vorspannungen in den Lagern der Scherenachse und machen das Scherengetriebe spielfrei.
