ABSTRACT:
A scale testing vehicle for transporting certified weights and depositing them on the platform of truck scales, the vehicle body having a pair of rails supported above a truck bed carrying the weights and having a trolley carried by the rails for movement fore and aft. A cable is looped over pulleys at each end of the rail and is attached at one end to the trolley with its free end passing over a sheave on the trolley and supporting a bar having hooks for attaching to the weights. One of the pulleys may be moved to change the cable loop length, thereby raising or lowering the weights supported on the hooks. The bar has a counterweight which pivots the hooks when the weights are not supported therefrom so that the hooks clear the weights when moved horizontally. Hydraulic output from a truck engine driven pump is used to traverse the trolley as well as to raise and lower the weights so that transfer between truck and scale may be expeditiously accomplished.
