Abstract
This disclosure deals with a truck including a vertically movable van and a lift mechanism for raising or lowering the van. The lift mechanism includes two arms pivotally connected in a scissors configuration. The arms are also connected to the truck frame and to the frame of the van in a manner to raise or lower the van as the scissors arms are spread or closed. An extensible power unit is connected between the two arms and is operable to spread or close the arms in order to raise or lower the van. Improved reinforcements are placed on the truck frame to provide the necessary strength.
