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 14-38tonne wheeled and crawler excavators. Like the existing DXB100H, DXB170H and DXB260H models, the new DXB130H and DXB190H hydraulic breakers are said by Doosan to offer superior power-to-weight ratios, providing very efficient reduction of rock, boulders, concrete and other demolition waste, as well as excellent excavation work.

6902 Doosan Infracore Construction Equipment has added two new models to the company’s range of hydraulic breakers for use on Doosan 14-38tonne wheeled and crawler excavators.

Like the existing DXB100H, DXB170H and DXB260H models, the new DXB130H and DXB190H hydraulic breakers are said by Doosan to offer superior power-to-weight ratios, providing 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 22tonnes, 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 1,090kg and a blow energy of 2700Joules.

Designed for use on Doosan excavators from 22-30 tonnes, the DXB190H breaker has an operating weight of 1,815kg and a blow energy of 4000Joules. 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 and are said to offer several important features including a simple, robust design for economical and reliable performance, low maintenance costs, operator comfort and carrier protection.

Doosan says its 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, said to increase 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 are said to lower maintenance costs.

    Both machines are powered by Doosan’s DL06K ‘common rail’ six-cylinder turbocharged diesel engine, said to meet Stage IIIB engine emission regulations through the use of EGR (Exhaust Gas Recirculation) and Diesel Particulate Filter (DPF) after-treatment technologies. The engine has a displacement of 5,890cm³ and is said to deliver 15% more power [82 kW @ 1850RPM] than previous Stage IIIA models. The engine also delivers 11% more torque (49.5kgf.m) in the DX160LC-3 model. Doosan said that factory tests had
