ABSTRACT:
In a lifting and tipping mechanism a lever drive unit includes two pairs of scissors arms with each pair pivotally mounted on an oppositely disposed leg of a U-shaped undercarriage, a swing mechanism is provided for guiding the movement of the scissors arms from a folded position on the undercarriage to an extended lifting and tipping position upwardly from the undercarriage. The swing mechanism consists of an elongated sliding guide in which a guide member, fixed to one end of one of the scissors arm of each pair is slidably displaced by a hydraulic linear motor. The sliding guide has a first part which extends parallel to the legs of the undercarriage in the folded position of the scissors arms and a second part which extends angularly upwardly from the first part. As the scissors arms open from the folded position, the guide member moves from the first part into the second part. The sliding guide can be formed in a single member or it can be made up of two separate members.
