Rig-mounted hydraulic breaker with increased impact energy

International construction equipment manufacturer Chicago Pneumatic has launched the RX12, a rig-mounted hydraulic breaker for carriers between 9-15 tonnes.

Compared to its predecessor model, the RX12 offers increased output power and impact energy.

 With a service weight of 625kg and a tool diameter of 90mm, the RX12 delivers a combination of high reliability and efficient performance. It is suitable for a range of light demolition, landscaping, building renovation, mining, 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. It has a central lubrication point for manual greasing, but can also be equipped with an automatic lubrication device called CP-Lube.

The RX12 also 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.
