ABSTRACT:
An improved scale testing cart for selectively positioning scale calibration weights on platform scales is disclosed. The scale testing cart has a weight bed for retaining selected calibration weights and has a tubular frame adjacent one end of the weight bed which is adapted for holding a fluid. A first pair of wheels is attached to the weight bed at a position adjacent the tubular frame and a second pair of wheels is attached at the end of the weight bed which is opposed to the tubular frame. A hollow member is positioned between the second set of wheels and is adapted to retain ballast. A lift bar for engaging a lifting apparatus is positioned substantially at the weight center-line of the cart. Located adjacent the tubular frame is a drive means which generally includes a drive engine, gas tank, and hydraulic drive pump for propelling the cart.
