Chicago Pneumatic has launched the RX12, a powerful new rig-mounted hydraulic breaker for carriers between 9-15 tonne. Compared to its predecessor model, the RX12 offers a 10 per cent increase in output power and a 28 per cent increase in impact energy.

With a service weight of 625 kg and a tool diameter of 90 mm, the RX12 delivers a combination of high reliability and efficient performance; making it ideal for a range of light demolition, landscaping, building renovation and road construction applications.

The RX12 features an innovative mono-block design, with the cylinder and tool holder integrated in one piece. This reduces the total number of parts, and eliminates the need for side bolts, to increase overall reliability. The inclusion of a replaceable cylinder sleeve also cuts repair time and costs. 

The new breaker?s double tool retainer bars ensure optimal working tool guidance, with a one-piece floating wear bush enabling quick and easy field replacement of the working tool. The RX12 has a central lubrication point for manual greasing, but can also be equipped with an automatic lubrication device called CP-Lube.

To lower stress levels for man and machine, the RX12 has a breaker box guidance system that dampens noise and vibration levels. As with all hydraulic breakers in the RX range, the RX12 features gas/oil hybrid technology, an internal control valve, and a Power Booster mode that reuses wasted recoil energy for increased efficiency and performance.
