803086757 Right Boom Cylinder – XCMG XC760K Skid Steer Loader Related Spare

A boom lift cylinder (also called lift cylinder, boom hoist cylinder, or boom hydraulic cylinder) is the core hydraulic actuator in the boom lifting system of a skid steer loader. The boom is installed above the rear of the machine body via pivot shafts, with a quick-coupling bracket at the front driven by hydraulic cylinders for lifting . The extension and retraction of the boom cylinder directly controls the raising and lowering of the boom—the key actuator enabling the loader to perform loading, lifting, and dumping operations.

The boom structure of skid steer loaders varies by model: some adopt a twin-cylinder parallel​ arrangement, with one boom cylinder on each side jointly driving the boom lift to handle heavier working loads ; others use a single cylinder combined with a four-bar or six-bar linkage to control both boom lift and bucket attitude . Under different structural forms, the quantity, mounting position, and stress state of the boom cylinder differ accordingly.
