What It Does:

Serves as the primary blade lift hydraulic actuator mounted between the front main frame and the dozer blade linkage on Caterpillar D7G series track-type tractors. Powered by high-pressure hydraulic fluid, it extends and retracts across a 120.65 mm bore and 955.50 mm stroke to raise, lower, and apply down-pressure to the heavy dozer blade, controlling blade cutting depth, penetration, and earth-grading levels.

Importance:

A critical kinematic and load-bearing hydraulic drive component essential for blade penetration force, vertical cutting stability, and overall earthmoving efficiency in demanding land clearing, quarrying, and road construction applications. Built with a robust 49.5 kg heavy-walled barrel and high-strength forged rod structure, it effectively withstands immense axial thrust loads, severe cyclic bending moments, and dynamic ground shock pulses encountered during tough rocky ground cutting, while advanced heavy-duty seals prevent fluid bypass under continuous high-pressure operation.
