What It Does:

Serves as the bucket hydraulic actuator controlling bucket curl and dump functions on Caterpillar 320C and 322C 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 164 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.
