A boom cylinder (also called lift cylinder, boom hoist cylinder, or boom hydraulic cylinder) is the core actuator in a loader's working-device hydraulic system, installed between the frame and the boom. Through hydraulic extension and retraction it drives the boom up and down, working together with the tilt cylinder to complete the loading, lifting, and dumping cycle. A loader's working hydraulic system typically consists of a hydraulic tank, working pump, distributor valve (multi-way valve), boom cylinders, tilt cylinder, lines, and control devices; the boom cylinder handles boom lifting and lowering, while the tilt cylinder handles bucket flipping .
The XGYG01 series part numbers in XCMG loaders correspond to multiple cylinder types within the working hydraulic system—which must be distinguished when ordering and replacing:
Tilt cylinder: Handles bucket flipping, e.g., drawing XGYG01-001 .
Left & right boom cylinders: Handle boom lifting, e.g., drawing XGYG01-141/142 .
Steering cylinder: Handles whole-machine steering, e.g., drawing XGYG01-004 .
