International construction equipment manufacturer Chicago Pneumatic (CP) has launched the RX12, a powerful new rig-mounted hydraulic breaker for carriers between 9-15 t.

CP said that compared to its predecessor, the breaker offers a 10% increase in output power and 28% more impact energy.

“With the RX12 we have further improved our hydraulic breaker portfolio, and are now able to offer our customers a solution that delivers both increased power and consistently reliable performance,” said Ralf Majchrzak, spokesperson for rig-mounted attachments at Chicago Pneumatic.

With a service weight of 625 kg (1,377 lb) and a tool diameter of 90 mm (3.5 in), the RX12 delivers a combination of high reliability and efficient performance, making it ideal for a range of applications including light demolition.

It includes a 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, increasing 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.
