FIELD: physics.
SUBSTANCE: device includes a force driver, load limiter, electrohydraulic amplifier, timing valves, check valves, load limiter, automatic control unit, two-port on/off control valves with a flow section varied in accordance with a preset sequence. The input of the two-port on/ff control valves is connected to lines through which the electrohydraulic amplifier moves actuating medium through timing valves to one of the chambers of the force driver and discharging from the other, and the output of the two-port on/off control valves is connected to a drain line. The two-port on/off control valves are controlled by an emergency automatic control system. Check valves serve to reduce excess pressure inside the force driver when discharging liquid.
EFFECT: easier operation and increased reliability of the stand.
