What It Does:

Serves as the heavy-duty dual tilt hydraulic actuator mounted on the blade linkage of Caterpillar D10N, D10R, D10T, and D10T2 series large mining track-type tractors (dozers). Powered by high-pressure hydraulic fluid, it extends and retracts to control both blade tilt (side-to-side angle) and blade pitch (fore-and-aft blade attitude), optimizing ground penetration and material rolling efficiency across hard rock and heavy overburden.

Importance:

Critical for defining blade cutting aggression, material retention, and overall dozing productivity in demanding open-pit mining operations. Featuring a large 235.00 mm bore and a massive 353 kg heavy-walled barrel and high-strength forged rod structure, it effectively absorbs extreme dynamic shock loads, severe torsional stresses, and rock impacts, while advanced internal seals prevent fluid bypass under continuous high-pressure operation.
