Most recently it launched its new Hydraulic Breaker HB 4100, which it claims, scores points in comparison with its predecessor model with less weight, better performance and higher efficiency.

“Both in terms of performance and efficiency,the improvement in comparison to the predecessor model is considerable”, explains Gordon Hambach, product line manager for Hydraulic Breakers, “here we were able to achieve increases in the double-digit percentage range.”

The theory behind the HB4100 is that reduced weight and better performance means that the size of hydraulic breakers can be reduced. A lighter breaker also means that a smaller excavator can also be selected. That saves investment and operating costs.

Hambach added: “The follow-up costs of an investment in a hydraulic breaker are many times greater than the pure acquisition costs. The reduction of these total cost of ownership involves the conserving of resources, such as energy and work time, as well as durability and simple maintenance concepts.”

Against this background, the guide system of the hydraulic breaker was also changed in order to make it even more stable and resilient. “Hydraulic breakers are ultimately subjected to use under the most extreme conditions,” Hambach adds. “A new covering for the retaining bar offers more protection, especially in the lower part of the hydraulic breaker which has to take a lot of wear and tear. There is also circumferential wear protection, which has proven its worth with all heavy hydraulic breakers from Atlas Copco.”

Doosan has perhaps been the most prolific launcher of new attachments on the OEM side of the sector recently launched the three new DXB100H, DXB170H and DXB260H hydraulic breakers for use on Doosan wheeled and crawler excavators from 14 to 38 tonne. The Doosan DXB100H breaker is suitable for the Doosan excavators up to 18 tonne, namely the DX140LC, DX140LCR, DX160LC crawler excavators and the DX140W, DX160W and DX170W wheeled excavators.  The DXB100H has an operating weight of 900 kg and a blow energy of 2350 J.

Designed for use on Doosan excavators from 20 to 28 tonne, the DXB170H breaker has an operating weight of 1620 kg and blow energy of 3400 J.  It is approved for use on the DX210W wheeled excavator and all the medium Doosan crawler excavators from the DX225LC to the DX255LC.

The Doosan DXB260H breaker is suitable for the Doosan excavators from 30 to 34 tonne, namely the DX300LC and DX340LC models.  The DXB260H has an operating weight of 2450 kg and a blow energy of 5000 J.

Staying with excavators its new Geith ripper has been designed to give an excavator a powerful ripping ability in hard ground conditions as well as in the most demanding demolition applications. The ripper is engineered to reduce excessive stress on the excavator. The ripper is available for machines from 2 tonne to over 80 tonne in weight and offers a work depth of up to 1550 mm (62 inch).

Under Doosan Geith remains a world leader in the design and manufacture of couplers and attachment products for excavators and is launching new safety-focused, automatic quick couplers for a range of excavator sizes at Intermat 2012 as well as new ranges of heavy duty excavator buckets, tilt buckets and ripper attachments.
