What It Does:

Serves as the heavy-duty hydraulic tilt actuator controlling the bucket articulation on Caterpillar 990K large wheel loaders. Powered by high-pressure hydraulic fluid, it extends and retracts to roll back or dump the massive loader bucket during heavy bulk material handling.

Importance:

Essential for delivering maximum bucket breakout force and secure load retention in severe quarrying, mining, and aggregate loading applications. Featuring a massive 950 kg heavy-walled barrel and forged steel rod, it is engineered to withstand extreme dynamic shock loads and bending stress without hydraulic power loss.
