Boom Suspension Unit for Loaders HSE
The load bearing line is linked to one or several hydraulic accumulators via a control valve. The accumulator(s) act as a hydro-pneumatic spring and as such decouple the source of the oscillation from the rest of the vehicle, and therefore from the driver. The accumulator should be sized in consultation with Hydac in order to achieve the optimum overall system.
Function
The check valves (9) ensure that the highest pressure at any one time is available to the control circuit. With valve (3) in the deenergised position, the valve piston (2) is held in the closed position by the control pressure which breaks the connection from the boom unit to the accumulator and to the
tank. In this condition, the pressure equalization valve (4) is also unloaded. This valve equalizes the pressure in the working line on the piston side and the pressure of the accumulator. If the accumulator pressure exceeds the working line pressure, the excess accumulator pressure is relieved to tank. This prevents unintentional hoisting movements when the suspension is connected. The pressure relief valve (6) protects the accumulator (5) from excessively high pressures.
