Doosan Launches New HB-series 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 optimized and fully certified for Doosan excavators with carrier weights from 1.2 to 15 tonne. As a result, Doosan HB breakers offer the highest possible productivity, whether the operator is demolishing concrete or breaking rocks.

The high quality of the breakers is backed by an industry-leading 2 year warranty and they are available at cost-effective prices, providing customer benefits in terms of total cost of ownership. According to Doosan, all these features together are aimed at greatly exceeding customer expectations for hydraulic breakers.

In common with all Doosan machines and attachments, the new Doosan breakers are covered by the outstanding Doosan dealer service network and Doosan product specialists, providing fully comprehensive ‘one-stop service’ support.

High quality, extended life design

The service life of the breakers 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.

HB-Series offers choice of five hydraulic breaker models

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.
