摘要:The specification discloses an apparatus for moving a load between loweredand inclined positions, the apparatus comprising a load-carrying body having a center ofgravity, the load-carrying body pivotally supported on a base for selective pivotal
movement between a lowered position and an inclined position by a four-pivot axislinkage mechanism comprising at least first and second pivotal linkages. The linkagemechanism carries the load-carrying body rearwardly in relation to the base along a pathof travel between fully lowered, intermediate, and fully inclined positions of the load-carrying body, along which path of travel the center of gravity of the load-carrying bodyis lowered between the fully lowered and intermediate positions thereof, and raisedbetween the intermediate and fully inclined positions thereof.
