44 • ROCK products • April 2018 EQUIPMENT & TECHNOLOGY CRUSHING & BREAKING Epiroc AB, the subsidiary of Atlas Copco Group that is planned to be listed on the stock exchange in 2018, announced that its premium SB series hydraulic breaker attachments are the industry's only breakers to come standard with an internal water port for dust suppression, a feature that can assist in compliance with silica rule dust regulations. With an integrated water channel, operators can spray water at the source of dust creation to keep dust levels down. This improves the working environment, enhances visibility and prevents dust from seeping into the bushings. SB breakers are also designed to protect operators and equipment by reducing noise and vibration. Epiroc SB series breakers are designed for the 0.7- to 24-ton carrier class and are used in a wide range of applications that include demolition and renovation work, construction projects, tunneling, dredging and pile driving. Mining and quarrying applications range from overburden removal and scaling to primary, selective rock breaking. SB series breakers combine superior efficiency and perfor- mance with high durability in a compact design. The range includes models to match any micro or mini excavator, backhoe, skid steer loader or demolition robot with service weights ranging from 120 lb. for the SB 52, the smallest breaker of the SB Series, to 2,350 lb. for the SB 1102. Oil requirements range from just 3.2 gpm at 1,450 to 2,175 psi, to 35 gpm at 1,185 to 2,610 psi. Telsmith Iron Giant Jaw Crusher Offers Performance in Tough Environments Telsmith Inc. introduced the Iron Giant Crusher at the AGG1 Expo in Houston. To showcase the Telsmith promise that "The Extra Mile Isn't Extra. It's Included.," the team explained how Telsmith goes the extra mile with their concept to comple- tion services for the Iron Giant Crusher, which provides high performance and ease of maintenance for increased uptime and improved safety. The Iron Giant is available in two sizes, 4448 and 5060 with the 4448 weighing 126,000 lb. (57,154 kg) and 5060 weigh- ing 191,000 lb. (86,638 kg), respectively. The Iron Giant jaws are designed with a long crushing cham- ber that provides both high volume crushing and aggressive crushing action to deliver reliable performance even with the hardest materials such as basalt. To lower maintenance costs and maximize uptime the Iron Giant jaws incorporate maintenance features not normally found in jaw crushers such as replaceable liners that are built into several areas to protect major components from wear. Safety Safety is engineered into every Telsmith piece of equipment. One of the main safety features of the Iron Giant is the trou- ble-free wedge lock adjustment system, which is safe even after years of service in the toughest operating conditions. To begin adjustment, hydraulic cylinders do the heavy work of unlocking the wedge and moving the beam forward. Easy to handle lightweight shims are used to fix the setting. Hydrau- lics then drive the wedge in place, firmly locking the beam into position. No special tools are needed to carry out the adjustment. The wedge lock system also incorporates a unique tension spring bracket that moves with the beam during adjustment. This saves time by eliminating the need to reset the spring each time the crusher setting is changed, getting the opera- tion up and running quickly.
