装置。 A live load is placed on the table, and the shafts at both ends of the tilt base, which are swingably supported by the drive of a motor, are supported by saddles, and cam plates are attached to each of the ends of the shafts. In a balance pressure adjustment device that connects hydraulically driven balance cylinders, strain gauges are attached to the outer periphery of both axes of the tilt base, and a preamplifier, voltage/current converter, and proportional pressure control valve are connected to the strain gauges by an electric circuit. A balance pressure adjusting device characterized in that the proportional pressure control valve is connected to the balance cylinder and arranged in a circuit for supplying pressure oil from a hydraulic unit to the balance cylinder.
