ABSTRACT:
A materials testing machine for testing equipment used for lifting or jacking up of objects. The machine has a frame with a generally horizontal arm extending outwardly therefrom. A hydraulic cylinder assembly is positioned along the horizontal arm and is connected to a pressure gauge. Lifting equipment may be connected between the frame of the machine and the end of the horizontal arm, and the amount of pressure exerted by the lifting equipment may be tested and the results read on the gauge thereof. A second hydraulic cylinder may be positioned over the platform so that a lifting jack may be similarly tested.
