ABSTRACT:
Apparatus for assisting in opening and closing the side of a truck-body is shown and described. Illustratively, a pully is mounted eccentrically on one end of the shaft to which the swingable portion of the truck roof is fixed. A system of traction cables and a tension spring combine with gravity forces acting on the pivotal lower lateral wall portion of the truck to reduce the effort needed to open and close the side of the truck.
