Doosan extend hydraulic breaker range

Doosan DXB130H breaker

New DXB130H and DXB190H breakers for use on Doosan excavators in 14- to 38-tonne class

DOOSAN Infracore Construction Equipment have added two new models to their range of hydraulic breakers for use on the company’s wheeled and crawler excavators from 14 to 38 tonnes. As with the existing DXB100H, DXB170H and DXB260H models, the latest DXB130H and DXB190H breakers offer excellent power-to-weight ratios to provide efficient reduction of rock, boulders, concrete and other demolition, as well as excavation work.

The DXB130H breaker, which has an operating weight of 1,090kg and blow energy of 2,700J, is suitable for excavators up to 22 tonnes in weight; this includes the Doosan DX160LC and DX180LC crawler excavators, and the DX160W, DX170W, DX190W and DX210W wheeled machines.


Designed for use on Doosan excavators from 22 to 30 tonnes, the DXB190H breaker has an operating weight of 1,815kg and blow energy of 4,000J. It has been approved for use on the medium to large size crawler excavators from the DX225LC to the DX300LC.

The DXB technology utilized on the hydraulic breakers ensures the carrier is protected from the effects of reduction in pressure peaks. The breakers feature an energy-recovery system and a patented valve system, to increase overall performance.

They also include: a high-quality piston and cylinder manufactured to precise tolerances; and an advanced dampening system to protect the breakers against blank firing. The close tolerances of the parts used in the breakers are said to result in reduced maintenance.
