What It Does:

Serves as the heavy-duty ripper hydraulic actuator operating on the rear ripper linkage of Caterpillar D10T2 track dozers. Powered by high-pressure hydraulic fluid, it extends and retracts to drive the ripper shank into hard rock, compacted strata, or frozen ground to shatter and loosen tough material prior to pushing.

Importance:

Essential for achieving maximum ripper penetration force and operational efficiency in severe mining, quarrying, and land-clearing applications. Featuring a robust 232 kg heavy-walled barrel and high-strength forged rod, it effectively absorbs extreme dynamic shock loads and severe torsional bending forces, while advanced internal seals prevent fluid bypass under continuous heavy operation.
