<p>The cylinder (1) and its pressure accumulators (2) can be connected via an inlet valve (6) to the pressure side (P) of the hydraulic pump used to carry out the lifting work, so that the cylinder and accumulators can be filled with oil. Once the pressure required to obtain the desired balancing is measured, the motor is stopped and the valve is closed, separating the cylinder system from the lifting system. A check valve (7) is located after the inlet valve to prevent a fall in pressure caused by e.g. a return leakage flow through the pump. A discharge valve (8) is used to return oil from the balancing system to the oil tank for the truck in order to deactivate the balancing system.</p> |
