What It Does:

Serves as the stick (dipperstick) hydraulic actuator controlling arm extension and retraction on Caterpillar 320D, 320E, 321D, and 323D/E series hydraulic excavators. Positioned between the main boom and the bucket linkage, it converts high-pressure hydraulic fluid power into linear mechanical force to extend the arm out for maximum reach and pull it inward during digging and crowding operations.

Importance:

Essential for defining digging depth, reach, and stick breakout force during trenching, heavy excavation, and earthmoving tasks. Featuring a robust 270 kg heavy-walled barrel and high-strength forged rod structure, it effectively absorbs severe dynamic shock loads, rock impacts, and heavy bending stress, while advanced internal seals prevent fluid bypass under continuous high-pressure operation.
