What It Does:

Serves as the bucket hydraulic actuator controlling bucket curl and dump functions on Caterpillar 311C, 312C, 312C L, 314C, 320C, 323D L, 325C, 325D, and 330C series hydraulic excavators. Powered by high-pressure hydraulic fluid, it extends and retracts to drive bucket digging, material loading, and dumping cycles.

Importance:

Essential for generating optimal bucket breakout force and maintaining smooth operational cycle speeds during excavation, trenching, and earthmoving tasks. Featuring a robust 84 kg heavy-walled barrel and high-strength forged rod, it effectively absorbs dynamic shock loads and severe torsional stress, while advanced internal seals prevent fluid bypass under continuous operation.
