What It Does:

Serves as the hydraulic pin puller actuator mounted on the rear ripper assembly of Caterpillar D6R and D6T series track-type tractors (dozers). Powered by high-pressure hydraulic fluid, it provides a high-force, short-stroke linear motion to disengage and engage the heavy locking pin, allowing the operator to adjust ripper shank position and penetration depth directly from the cab.

Importance:

Essential for enabling quick, safe, and effortless ripper shank adjustments under demanding mining and earthmoving conditions without manual labor. Built with a heavy-duty 90 kg compact, thick-walled barrel structure, it effectively withstands severe vibrations, heavy dynamic impacts, and side-loads transmitted through the ripper shank during rock-ripping operations, while high-performance internal seals prevent hydraulic bypass under continuous pressure.
