Crush the Competition: Industrial-Strength Breaking for 6 to 9-Tonne Machinery

Product Description The EarthQuake RB70S Hydraulic Rock Breaker is a true heavy-hitter, specifically engineered for mid-sized excavators in the 6.0 to 9.0-tonne range. This is the ultimate attachment for contractors tackling serious demolition, heavy rock excavation, and large-scale civil works. Built to withstand the high-intensity demands of 7-tonne and 8-tonne machines, the RB70S combines raw striking power with the sophisticated "S-Series" silenced technology. The result is a hammer that dominates the job site while meeting strict noise regulations. Its reinforced internal structure and vibration-absorbing cradle ensure that the massive energy is directed exactly where it belongs—into the material, not your machine.

Product Features

• Massive Impact Energy: Precision-engineered to harness the high hydraulic flow of 6-9t excavators, delivering maximum breaking force per blow.

• Reinforced Silenced Housing: The heavy-duty enclosed cradle protects the power cell from side impacts while keeping decibel levels low for urban environments.

• Pro-Level Vibration Control: Features an enhanced dampening system that isolates the breaker’s recoil, protecting your excavator’s boom and hydraulic seals from premature wear.

• Optimised Valve System: Designed for consistent performance under high-pressure conditions, ensuring the hammer maintains its strike rate during long shifts.

• Dual-Retainer Pin Design: Includes a robust tool-retaining system for added safety and more even wear on the heavy-duty chisels.

• Maximum Tool Diameter: Equipped with a larger, high-tensile chisel specifically sized for the 70-series power cell to handle reinforced concrete and volcanic rock.

Frequently Asked Questions

• Is my machine’s hydraulic output sufficient for the RB70S? The RB70S is perfectly matched to the higher flow rates of 6t to 9t excavators. We will confirm your machine’s flow and pressure specifications to ensure the breaker is tuned for maximum efficiency without straining your pumps.

• Will I need a custom hitch to fit my 8-tonne excavator? No need for extra parts. We supply the RB70S with a head bracket custom-built to your machine's specific pin dimensions and ear spacing, ensuring a secure, factory-standard fit.

• What is the greasing requirement for a breaker of this size? Due to the massive forces generated by the RB70S, it is essential to grease the tool shank every 1 hour of operation. This prevents heat-related scoring and significantly extends the life of your bushings and chisels.

• Can the RB70S handle reinforced concrete demolition? Absolutely. This breaker is specifically designed for high-density materials. The 70-series power cell provides the necessary penetration force to shatter reinforced concrete and large boulders effectively.
