Manual Extract – Accumulator

Liquids are practically incompressible and are therefore unable to store pressure energy.
To achieve the storage of liquids, the compressibility of a gas is used. In the accumulators used in the machine, “nitrogen” is used as the medium.
The tasks of the accumulator are:
– Storage of pressure oil for the servo control system, brake system and oscillating axle support.
– Cushioning of hoist movements for hydraulic operator’s cab elevation and industrial stick.
The accumulator consists of a hydraulic section and a gas section in a metal pressure vessel.
Accumulators are classified according to their design:
– Diaphragm accumulator 10
– Bladder accumulator 20
– Piston accumulator 30
See design and functional descriptions below.
