Hydraulic Accumulator – Agris Group Brand

A hydraulic accumulator is a device that stores the energy of pressurized hydraulic fluid and releases it when needed. In front loaders, it is used as part of the boom's shock-absorption system.

Main Functions

-Shock and vibration absorption: when moving with a load over uneven ground, the hydraulic accumulator absorbs hydraulic shocks, reducing the load on the frame and hydraulic cylinders.

-Structural protection: reduces the risk of cracks appearing in metal structures and extends the service life of components.

-Operator comfort: reduces machine sway, ensuring smooth movement and stable control.

-Fuel savings: reduced oscillation allows faster travel with a load, without wasting energy on braking and acceleration.

Application Features

-Installed in the boom lift hydraulic line.

-Work in tandem with a hydraulic valve that engages/disengages the shock-absorption system.

-Working pressure is typically 160–250 bar, depending on the loader model.

-Requires regular maintenance: checking the gas (nitrogen) pressure and the condition of the diaphragm/piston.

Thus, hydraulic accumulators in a front loader's shock-absorption system are a key element for increasing equipment longevity, operational safety, and operator comfort.
