The Chicago Pneumatic RX hydraulic breaker line offers 13 models, which are designed to match various application needs found in demolition, primary/secondary breaking, trenching and foundation work, recycling, road construction and landscaping.
With a service weight of 200 lb. (94 kg), the RX 2 breaker fits carrier classes with weights ranging from 2,000 to 7,000 lb. (907 to 3,175 kg). On the top end, with a service weight of 9,000 lb. (4,200 kg) the RX 53 is appropriate for carriers in the 88,000 to 154,000 lb. (39,916 to 69,853 kg) weight class. RX hydraulic breakers feature an established hybrid gas/oil technology and are engineered with fewer components and working parts to maintain.
The CP power boost feature on the RX models is designed to achieve greater breaking performance in tough applications without requiring additional hydraulic input. While the impact energy remains constant, the breaker increases the impact rate, resulting in enhanced percussive performance. The power stop function found on models RX 14 and up reduces blank firing, and is designed to reduce wear on the breaker and carrier while increasing the working life of the components, according to the manufacturer.
The larger models in the Chicago Pneumatic RX line, RX 25 through RX 53, feature a power control valve, which enables the operator to adjust the breaker’s performance according to the application. The RX 25 through RX 53 models also feature a fastening system that uses side bolts and an insert thread system that ensures a long working lifetime and improved load distribution at the tap hole.
