Powerful breaking

695 Doosan has a new DXB170 hydraulic breaker for use on 18-28tonne excavators. Features include a simple, robust design, low maintenance costs, operator comfort and carrier protection. DXB technology ensures the carrier is protected from the effects of reduction in pressure peaks. The DXB170 breaker includes an energy recovery system and a patented valve system, increasing performance; a high quality piston and cylinder manufactured to precise tolerances; and an advanced dampening system to protect the breakers against blank firing. The close tolerances of the parts used in the breakers result in lower maintenance costs. The high power-to-weight ratio of this breaker provides very efficient reduction. The unit weighs 1.62tonnes, has an operating pressure of 180bars and a 137mm diameter tool.
