What It Does:

Serves as the complete bucket hydraulic cylinder actuator controlling bucket curl and dump functions on Caterpillar 345 and 349 series heavy hydraulic excavators. Powered by high-pressure hydraulic fluid, it extends and retracts to drive bucket digging, material retention, and dumping cycles.

Importance:

Essential for generating optimal bucket breakout force and maintaining high operational cycle speed during heavy excavation, mining, quarrying, and earthmoving tasks. Featuring a robust 394 kg heavy-walled barrel and high-strength forged rod structure, it effectively absorbs dynamic shock loads, rock impacts, and severe torsional stress, while advanced internal seals prevent fluid bypass under continuous heavy operation.
