EarthQuake RB40S Rock Breaker 3.6-4.5T

Unleash Maximum Impact: The Ultimate Breaker for 4-Tonne Class Machinery

Product Description The EarthQuake RB40S Hydraulic Rock Breaker is a high-performance attachment specifically engineered for excavators in the 3.6 to 4.5-tonne class. Delivering a powerful blow with every strike, the RB40S is the ideal partner for demolition, trenching, and site preparation tasks. Built with a slimline, compact design, it allows for superior visibility and access in confined spaces without sacrificing impact energy. Featuring advanced vibration dampening and a silenced housing, this breaker reduces operator fatigue and noise pollution on-site, making it perfect for urban environments and heavy-duty commercial applications alike.

Product Features

• Optimised Power-to-Weight Ratio: Specifically tuned for 3.6–4.5t excavators to provide maximum breaking force without compromising machine stability.

• Silenced Housing (S-Series): Features a fully enclosed protective cradle that significantly reduces noise levels and protects the internal power cell.

• Advanced Vibration Dampening: High-quality buffering materials reduce the shock transmitted to the excavator’s boom and the operator.

• Minimal Moving Parts: Simple, robust internal engineering ensures lower maintenance costs and higher reliability over a long service life.

• Hard-Wearing Tool Steel: Supplied with high-quality chisels designed to withstand the most abrasive rock and concrete conditions.

• Easy Maintenance Access: Designed for straightforward servicing, including easily accessible grease points and replaceable bush systems.

Frequently Asked Questions

• Will my excavator’s hydraulic flow handle the RB40S? The RB40S is engineered to operate efficiently within the standard flow ranges of 3.6t to 4.5t machines. We match the breaker to your machine’s auxiliary hydraulic output to ensure high-impact performance without overheating your hydraulic system.

• Does this breaker come with a hitch plate to fit my specific machine? Yes. We supply the RB40S with a head bracket custom-manufactured to your excavator’s specific pin dimensions, ensuring a perfect fit and immediate "plug-and-play" operation.

• How often do I need to grease the breaker? To ensure the longevity of the tool and bushings, we recommend greasing the RB40S every 1 hour of operation. This frequent lubrication is essential to prevent heat build-up and metal-on-metal wear during heavy breaking.

• What is the advantage of the "Silenced" S-Series housing? The fully enclosed box housing significantly reduces decibel levels, which is a requirement for many urban job sites. Additionally, the frame protects the internal power cell from impact damage and debris, extending the life of the attachment.
