Working principle of hydraulic cylinder:

1.  Core structure & function 30/40/50 series amplitude variation hydraulic cylinders adopt double-acting hydraulic design, serving as key drive parts for excavators and aerial work vehicles to adjust boom angles and bear loads.

2.  Amplitude adjustment logic Controlled by multi-way valve, high-pressure oil alternately flows into two cylinder chambers: Oil into rodless chamber: Piston rod extends, lifts boom, enlarges working radius; Oil into rod chamber: Piston rod retracts, lowers boom, shortens radius for narrow space operation.

3.  Anti-leakage & shock buffer design Multi-layer combined seals block mud and dust to prevent internal oil leakage; Built-in end buffer cavities generate oil damping at stroke limits, avoiding rigid collision between piston and cylinder cap to protect the boom.

4.  Load matching performance 3 size options fit light, medium and heavy-duty machinery. It keeps steady torque during frequent amplitude changes, balances the weight of platform and cargo, and guarantees stable, safe high-altitude operation.
