As with the existing DXB100H, DXB170H and DXB260H models, the new DXB130H and DXB190H hydraulic breakers are said to 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 22tonnes (Doosan DX160LC and DX180LC crawler excavators and the DX160W, DX170W, DX190W and DX210W wheeled excavators). It has an operating weight of 1,090kg and a blow energy of 2700 J.
Designed for use on Doosan excavators from 22-30tonnes, the DXB190H breaker has an operating weight of 1,815kg and a blow energy of 4000 joules. It is approved for use on the medium to large-sized Doosan crawler excavators from the DX225LC to the DX300LC model.
Doosan says that 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.
