New Doosan hydraulic breakers

New Doosan hydraulic breakers

Doosan Infracore Europe has launched the new HB-series hydraulic breaker range for the European market. The new range of five HB-series breakers provides a novel concept with high performance and a simplified design, specifically optimised and fully certified for Doosan excavators with carrier weights from 1.2- to 15-tonne.

Backed by a two-year warranty, the breakers' service life is extended through the adoption of an advanced heat treatment process and quality proven materials for key components including the cylinder and piston. The energy of the piston stroke is accumulated by charged nitrogen gas and the breakers use an inward valve system with a simple structure and fewer inner parts.

A urethane damper prevents vibration that might damage the carrier and improves operator comfort. The front head supports the breaker and assemblies with bushing, which buffers the shock from the tool. The low noise housing is ideal for working in urban zones, where noise levels must be controlled or where local regulation may require silenced breakers.

The HB-series range offers five hydraulic breaker models – the HB03, HB04, HB06, HB08 and HB15 – for use on Doosan mini-excavators and Doosan crawler and wheeled excavators, covering carrier weights from 1.2- to 15-tonne. Ideally suited for demolition work, the Doosan breaker range is also intended for general construction, rental, quarrying and mining applications.

The range begins with the HB03 breaker, which is suitable for use on the Doosan DX17z 1.7-tonne and DX19 1.9-tonne mini-excavators. Next in the range is the HB04 model for the DX27z 2.7-tonne and DX35z 3.5-tonne mini-excavators. The third model in the range – the HB06 breaker – is designed for use on the 6-tonne Doosan DX57W-5 wheeled excavator and DX62R-3 and DX63-3 mini-excavators.

The fourth model in the range is the HB08 breaker for use with the Doosan DX85-3 8-tonne mini-excavator. The top-of-the-range HB15 hydraulic breaker is designed for use with the Doosan DX140LC-5, DX140LCR-5 and DX160LC-5 crawler excavators and the Doosan DX140W-5, DX160W-5 and DX165W-5 wheeled excavators.
