Mobile Rockbreaker
Astec’s Series of Mobile Rockbreakers are a heavy duty, low profile vehicle. Designed for breaking oversized rocks during underground work.
Optimized Breaking Performance:
Reach best breaker performance with the help of four hydraulic stabilizers. Capable of levelling the machine on any ground condition. When supported on the four stabilizers the full weight of the machine is available for raking and breaking jobs, regardless of ground conditions. The stabilizers also removes the swaying motions of the engine end axle. Resulting in excellent machine stability during boom and breaker operation.

Rugged Construction:
- Normal operation of the Rockbreaker imposes side and torsional loading of the boom assembly when the machine is used to rake and manipulate oversize.
The Breaker Boom has been specifically designed with an integral sub-frame to provide additional rigidity and strength to the base carrier frame. - Boom sections are fabricated from high-strength carbon steel with reinforced ends.
- A massive swing post is mounted on self-aligning bushings. Pivot pins are oversized alloy steel with replaceable hardened steel bushings.
- All hydraulic boom cylinders are equipped with oversized rods and self-aligning bushings at each end to prevent side loading of the cylinders during raking and breaking operations.
