Ride Control Accumlator - Hitachi ZW180 Technical Manual

COMPONENT OPERATION / Ride Control Valve
RIDE CONTROL ACCUMULATOR
The ride control accumulator is installed in the
accumulation circuit of the ride control.
High-pressure nitrogen gas is contained in the
accumulator and pressure oil compresses nitrogen
gas via the piston.
Compression of nitrogen gas dampens shock of
pressure oil due to pitching of the lift arm cylinder raise
circuit.
IMPORTANT: The ride control accumulator cannot

be disassembled. Replace the ride
control accumulator as an assembly
if necessary.
