A load receiving platform and cradle are mounted for rotation about a horizontal axis through approximately ninety degrees. A machine base is spaced upwardly from a floor surface by supports which may be embodied in load cells. A load receiving surface of the platform extends along a cantilever portion of the platform. A hydraulic cylinder, coupled to the cantilever portion of the platform, imparts rotational movement thereto. The hydraulic cylinder is part of a hydraulic system having lines communicating cylinder ends with a pressure source. One of the lines includes a piloted valve with fluid flow through the line being regulated by pilot pressure taken from the remaining line to control platform movement during an unbalanced condition of the platform.
