Doosan Extends Hydraulic Breaker Range

Doosan Extends Hydraulic Breaker Range

Doosan Infracore Construction Equipment has added two new models to the company's range of hydraulic breakers for use on Doosan wheeled and crawler excavators from 14 to 38 tonne. Like the existing DXB100H, DXB170H and DXB260H models, the new DXB130H and DXB190H hydraulic breakers offer superior power-to-weight ratios to provide very efficient reduction of rock, boulders, concrete and other demolition waste, as well as excellent excavation work.

The new Doosan DXB130H breaker is suitable for excavators up to 22 tonne, namely the Doosan DX160LC and DX180LC crawler excavators and the DX160W, DX170W, DX190W and DX210W wheeled excavators. The DXB130H breaker has an operating weight of 1090 kg and a blow energy of 2700 J.

Designed for use on Doosan excavators from 22 to 30 tonne, the DXB190H breaker has an operating weight of 1815 kg and a blow energy of 4000 J. It is approved for use on the medium to large-sized Doosan crawler excavators from the DX225LC to the DX300LC model.

All Doosan breakers are intended for demolition, construction and mining applications, offering several important features including a simple, robust design providing both economical and reliable performance, low maintenance costs, operator comfort and carrier protection.

DXB technology ensures the carrier is protected from the effects of reduction in pressure peaks. The breakers include an energy recovery system and a patented valve system, increasing overall performance; 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 result in lower maintenance costs.
