| New generation of solid body hydraulic breakers  Atlas Copco Construction Tools AB launched two extra machines of a new generation of solid body breakers: the SB 100 mk2 and SB 150 mk2. This is in addition to the new SB 200 already launched earlier. The new SB's hit harder, faster and are easier to install. The noise and vibration levels of the new SB's have been considerably reduced, due to a new hammer mechanism with recoil dampening. Vibrations and noise have also been cut thanks to the new compact design of the breaker. Additionally, the slim-line shape improves visibility of the tool and makes it easier to work in confined spaces – inside buildings, forexample, or in narrow trenches.The new SB design now includes a new floating bushing which is extremely easy to replace. With a solid body design, you have less parts than a traditional breaker because you have neither side bolts nor through bolts to hold side plates together. The new SB's have evenless parts than the first SBC generation making them even more reliable and easier to service. A built-in pressure relief valve is now supplied as standard to prevent using the SB breaker above its recommended operating pressure. Unparalleled reliability has always been the chief attraction of the solid body breakers. For example, the accumulator is now cast into the main body of the breaker and the charge nipple is fully protected. Not only is this a more robust design, but it also means you don't have to unbolt the accumulator before pulling out the hammer mechanism when you're re-sealing the breaker. write your comments about the article :: © 2006 Construction News :: home page |
