The result is higher impact rate from the same hydraulic input with less vibration. The slim, compact design makes SB breakers easier to handle and improves operator visibility. All SB breakers come prepared for compressed air supplies. No modifi- cation or additional installations are required. The multifunctional design of the well-protected connection ports assures trouble-free operation, ease-of-service, and quick access. Side-positioned ports reduce risk to hoses and provide easy access for connecting compressor, water connec- tion or ContiLube II micro lubrication supply lines or for monitoring operat- ing pressure. User-Friendly No special tools or adaptor fittings are required for servicing SB series break- ers. The SB SolidBody concept utilizes a patented internal, integrated com- ponent design integrating the impact mechanism and the guide system into a single piece. This eliminates the weak- est components of traditional breakers: damping and guiding elements, tie rods, parting lines and stud bolts. The accumulator is cast into the body, further reducing the number of breaker parts and overall weight and mainte- nance. Gas pressure can be checked and adjusted in a matter of minutes. The supported diaphragm reduces strain and distortion, improving load distri- bution and service life. Dual tool retainer pins optimize tool load distribution, require less grinding and protect against accidental damage to the tool and breaker. Other standard features of SB breakers include integrated pressure relief valve for overload protection, Auto Start, air inlet for underwater applications, oil drainage plug, dust wiper, slip fit bushing and dual tool retainer bars for better support. Epiroc ContiLube II or ContiLube II micro are options available for SB-Se- ries hydraulic breakers. In addition to hydraulic breakers, Epiroc offers an extensive line of hydraulic attachments including combi cutters, concrete busters, pulverizers, multi grapples, compactors, bucket crushers, hydro magnets, steel cutters, and drum cutters. Atlas Copco announced in January 2017 that the group will split into two com- panies in 2018: Atlas Copco, focusing on industrial customers, and Epiroc, focusing on mining, infrastructure and natural resources customers. Epiroc began operating as an independent business on Dec. 1, 2017, providing market-leading products and services to those industries. In the United States, the Epiroc organization started operat- ing under the Epiroc name as of Dec. 1, 2017. The Epiroc split with Atlas Copco is pro- ceeding according to plan, but remains subject to approval by Atlas Copco shareholders this month. Epiroc, Keestrack's track-mounted impact crusher units comprises three models, starting with the compact R3, which is proving itself on the market as a highly flexible 30-ton "construc- tion-site crusher." Keestrack's top-range R6 flagship model has a total weight of 60 tons when fully equipped and remains the most prom- inent machine among the 1300-impactors for recycling, large-scale projects, and quarrying applications. Thanks to the license-exempt dolly transport it readily competes with the much heavier competition within the 450-tph perfor- mance class. Moreover, the large-scale "Destroyer" unit has been available for several years as an R6e model in a diesel-electric hybrid version with electric motors driving the conveyor belts and screen components. Since 2014, the Keestrack R6e has been available with a 250-kW electric motor for the crusher and an electric 110-kW drive for the on-board hydraulic system, and optionally also the all-electric plug-in operation from the mains. Thanks to a high-performance on-board diesel engine, the large-scale crushers remain highly flexible, while up to 45 percent of the energy costs can be saved even in semi-sta- tionary operations.
