EarthQuake RB200SX Hydraulic Rock Breaker (18.0–22.0 Tonne Excavators)

Civil & Infrastructure Powerhouse: High-Production Breaking for 20-Tonne Excavators

Product Description The EarthQuake RB200SX Hydraulic Rock Breaker is an industrial-strength attachment purpose-built for large-scale civil engineering and heavy demolition projects. Specifically engineered for excavators in the 18.0 to 22.0-tonne class, this breaker is the go-to solution for bridge deconstruction, reinforced concrete removal, and deep utility trenching through hard-packed rock. The "SX" series features our most advanced silenced housing and smart-tooling technology, providing exceptional noise suppression and internal protection. Built for the high-intensity duty cycles of professional contractors, the RB200SX ensures rapid production rates while shielding your excavator from the stresses of heavy-duty breaking.

Product Features

• Massive Demolition Force: Precision-tuned to harness the high hydraulic flow of 20-tonne class excavators, making light work of reinforced foundations and heavy structures.

• Anti-Blank Firing (ABF) Technology: Automatically prevents the hammer from cycling when there is no resistance under the tool. This eliminates metal-on-metal "dry firing," significantly extending the life of the piston, tool pins, and front head.

• Impact Control (IC): Features a dual-speed stroke system that can be adjusted to match impact energy and frequency based on material hardness. This allows for higher blow speeds in softer materials and maximum impact energy in hard-rock demolition.

• Integrated Auto Greasing System: A factory-fitted lubrication system that constantly services the tool shank and bushes during operation, ensuring maximum uptime and reducing manual maintenance.

• Reinforced "SX" Silenced Housing: The heavy-duty, fully enclosed cradle suppresses noise for urban sites and provides 360-degree protection against falling debris.

• Pro-Level Vibration Dampening: Equipped with an industrial buffering system that isolates recoil, protecting your excavator’s boom, pins, and hydraulic system from stress.

Frequently Asked Questions

Is the RB200SX the right match for my 20-tonne or 22-tonne excavator? Yes. The RB200SX is perfectly balanced for the hydraulic outputs of the 18t to 22t bracket. We verify your machine’s flow and pressure settings to ensure the breaker is tuned for maximum impact frequency and efficient demolition.

How does the Anti-Blank Firing (ABF) protect my investment? The ABF system ensures the breaker only fires when downward pressure is applied. This prevents the piston from striking the tool without resistance—a major cause of catastrophic internal failure—meaning your breaker lasts longer and requires fewer repairs.

Does the Impact Control (IC) help with different types of breaking? Absolutely. The Impact Control allows the operator to match the breaker’s performance to the job. Whether you are breaking through reinforced concrete slabs (high frequency) or solid rock foundations (high impact), the RB200SX adapts to provide the most efficient production rate.

Is a custom-built hitch included for my machine? Yes. We supply the RB200SX with a heavy-duty head bracket custom-manufactured to your excavator’s specific pin dimensions, ensuring a secure and immediate "plug-and-play" fitment.

The RB200SX Rock Breaker

Suits all makes and models of excavator from 18 to 22 tonnes

Package includes:

• RB200SX Rock Breaker
• Head Bracket
• ABF - Anti Blank Firing
• IC - Impact Control
• Hoses and Fittings
• Tool Box and Nitrogen Recharge Kit
  
• 2x Chisels
• Premium Rock Breaker Grease and Grease Gun
• Auto Greasing System
• 2 Years Warranty

The RB200SX "X" upgrade features include:

Strengthened through-bolt mounting to increase maintenance intervals and overall longevity of the power cell.

ABF - Anti Blank Firing feature upgrade. ABF automatically stops operation of breaker when object is broken which protects damage to parts and extends the lifetime of breaker.

IC - Impact Control feature upgrade. IC allows the operator to control BPM (Beats per Minute) and power. Examples:

• For soft rock - High BPM / low Power
• For hard rock - Low BPM / high Power

Adjustment is infinitely variable between these to optimise the breakers production.

AGS - Auto Greasing System now pulse fed through the pressure side of the breaker. The AGS will supply the required amount of Premium Rock Breaker Grease to keep the moil lubricated and ensure longer maintenance intervals and increase breaker productivity.
