EarthQuake RB140SX Hydraulic Rock Breaker (11.0–16.0 Tonne Excavators)

Force Without Limits: The Ultimate Breaking Power for 14-Tonne Class Machinery

Product Description The EarthQuake RB140SX Hydraulic Rock Breaker is a high-production demolition powerhouse, specifically engineered for excavators in the 11.0 to 16.0-tonne range. Designed for the most demanding environments—from primary rock excavation to heavy civil infrastructure—the RB140SX delivers extreme impact energy with every strike. The "SX" designation represents our most advanced heavy-duty silenced housing, offering superior noise suppression and maximum protection for the internal power cell. Built for high-frequency operation, this breaker combines a slimline profile for deep trenching with a massive piston design that makes light work of reinforced concrete and high-density rock.

Product Features

• Exceptional Impact Performance: Calibrated to maximise the hydraulic output of 11–16t excavators, delivering industrial-grade breaking force for high-production job sites.

• Integrated Auto Greasing System: Features a factory-fitted automatic lubrication system that ensures the tool shank and bushes are constantly greased, maximising service life and reducing downtime.

• Heavy-Duty "SX" Silenced Housing: Features a reinforced, fully enclosed cradle that minimises noise pollution while shielding the power cell from extreme site conditions.

• Industrial Vibration Isolation: Equipped with an advanced buffering system that absorbs the massive recoil of the 140-series cell, protecting your excavator’s boom, pins, and seals.

• Optimised High-Flow Valve: Engineered to handle increased hydraulic flow and pressure without overheating, ensuring consistent performance during long, grueling shifts.

• Extreme-Duty Tooling: Supplied with oversized, high-tensile chisels designed to penetrate the hardest volcanic rock and heavily reinforced structures.

Frequently Asked Questions

Is my 13-tonne or 14-tonne excavator a good match for the RB140SX? Yes. The RB140SX is perfectly balanced for machines in the 11t to 16t bracket. We verify your machine’s auxiliary flow and pressure settings to ensure the hammer is tuned for maximum impact frequency and efficiency.

Does this breaker include a custom hitch for my specific machine? Absolutely. We supply the RB140SX with a head bracket custom-manufactured to your excavator’s exact pin dimensions (e.g., Hitachi, Cat, JCB), ensuring a perfect "ready-to-work" fit.

How does the Auto Greasing System benefit my operation? The RB140SX comes equipped with an Auto Greasing System, which automatically delivers the correct amount of lubricant to the tool and bushes while the breaker is in use. This eliminates the need for manual greasing every hour, significantly reducing wear and preventing costly damage caused by dry firing.

Can the RB140SX be used for heavy civil demolition? Yes. This model is specifically built for heavy-duty tasks including bridge demolition, primary trenching in rock, and secondary breaking of demolished concrete and rock resizing. Its high-impact energy is designed for high-density materials.
