Hydraulic Breaker

Atlas Copco’s SBU 340 solid body hydraulic breaker is for carriers in the 9,920-lb to 19,840-lb weight class. The solid body design of the SBU 340 removes the weakest parts of traditional hammers; there are no side bolts, no tie rods and no parting lines. Double retainer bars last longer than the retainer pins used on other breakers. The full-length floating tool bushing reduces wear on the bushing and working tool and helps prevent tool breakage. In addition, the simple tool retainer lock mechanism allows both components to be changed quickly and easily in the field with simple hand tools. The SBU 340 has an energy recovery design that captures reflected energy when breaking very hard rock. This design also reduces internal vibrations, which protects the carrier and reduces noise, while still achieving a 48% faster impact rate than its predecessor, the SB 300. The slim profile of the SBU 340 makes it easier for the operator to see and position the hammer. Its compact design is for applications in confined spaces such as indoor demolition work, along house walls, and in narrow trenches. The dust suppression ring and air injection porting make it ideal for special applications. Only 32.8 inches long, the SBU 340 can be tucked up under the carrier arm, and there is no need to remove the tool during transportation. www.atlascopco.com
