Doosan DXB breaker
Powerful and productive, the new Doosan breakers can be used in an array of difficult applications
The powerful and productive DXB breakers from Doosan are said to suit a wide array of applications such as tunneling, secondary reduction, primary winning and demolition. Simple and robust in design the units are said to offer low operating costs, low maintenance needs and a long working life. The wide range includes DXB30, DXB100, DXB170, DXB190 and DXB260 models, which cover carriers from compact machines such as mini-excavators and skid-steer loaders to large excavators. The breakers feature an energy recovery system and a patented valve system, increasing overall performance. Other features include a high quality piston and cylinder manufactured to precise tolerances and an advanced damping system to protect against blank firing. The compact DXB30 weighs 250kg and suits compact carriers from 3.5-7tonnes. The Doosan DXB170 weighs 1.6tonnes and is suitable for 18-28tonne excavators, while the 2.45tonne DXB260 breaker is designed for use on 27-37tonne excavators.
