Accumulator for Terex AC-250

The 12406612 accumulator is a hydraulic component designed to store fluid energy under pressure and release it as required by the machine systems. It functions to stabilize system pressure, absorb hydraulic shocks, and dampen pulsations generated by the pump. By maintaining a steady pressure, it ensures the hydraulic circuits operate with consistent responsiveness and efficiency.

This component is compatible with the Terex AC-250 all-terrain crane. It is integrated into various hydraulic subsystems, including braking, suspension, and stabilizer controls, where it provides auxiliary fluid supply and pressure stability. The unit is engineered to meet the specific volume and pressure requirements established by Terex for this machine model.

Hydraulic accumulators typically utilize a gas-charged chamber, often pre-charged with nitrogen, separated from the hydraulic fluid by a bladder, piston, or diaphragm. This design allows the component to compensate for fluid expansion and contraction, effectively smoothing out pressure spikes during operation. By absorbing these fluctuations, the accumulator protects downstream components from mechanical stress and ensures that critical systems maintain their intended performance levels during varied load conditions.
