Top 25Rollouts of 2012 This MINExpo year brought the introduction of a multitude of new and innovative products and equipment, from larger sizes with increased production to Tier 4 offerings with near-zero emissions. by Kerry Clines, Senior Editor and Therese Dunphy, Editor-in-Chief ATLAS COPCO CONSTRUCTION TOOLS Solid-body hydraulic breaker Atlas Copco says its new SB 702 hydraulic breaker is the world's only 700 kg hydraulic breaker with a solid body, making it compact and easy to handle. The percussion mechanism and guide system are integrated into a single block of steel, eliminating the need for side bolts. The integrated, maintenance-free accumulator is easily accessible, yet well protected from bangs and knocks. The unit works with a wide oil flow range and can be installed on a broad variety of carriers. Double tool-retainer bars minimize stress and wear on the working tools. Energy recovery helps to absorb recoil, resulting in less wear and tear on the carrier and more comfort for the operator. Atlas Copco Construction Tools; atlascopco.com.

When we ask readers how we can best help them keep track of changes in the products and services they use to produce aggregates, almost everyone wants an an- nual short list of the really important stuff. No wonder. The sheer volume of introduc- tions is overwhelming. Aggregates Manager covers dozens of products each year in its RollOuts departments and Supply Lines features. So each year, our staff reviews all the product introductions we've covered for the past year (our Top RollOuts "year" actually runs from the December 2011 issue through the November 2012 issue) to pick out 25 that we believe are worth further review. Our priorities are new con- cept products, which are rare; new series/ new generation products in categories that relate to the aggregates industry; and other rollouts which serve our readers' interests by increasing competition in a product category. CASE CONSTRUCTION EQUIPMENT Increased fuel economy Inevitably, we omit deserving products, either because we just didn't understand the significance of the product or because the announcing company didn't communi- cate what was special about the product, or both. In either case, we apologize in advance for these omissions. 22 Next-generation boom system BTI's new high-velocity control (HVC) boom system provides "fly by wire" computer-assisted control, allowing simultaneous dip and hoist functionality. This is said to enable greater production through rapid, smooth motion into and out of the gyratory crusher rock box. The "smart" boom features a high-horsepower electric motor, high flow-rate pumps with constant horsepower control, a high-flow di- rectional control valve, and an electrical boom position feedback for speed and pressure control.

Case's new 621F wheel loader features a 6.7-liter Tier 4 Interim engine that delivers up to 162 horsepower. A new dual-mode shutdown feature maximizes fuel economy and monitors vital engine components. The operator can limit idle time by using the fuel-saver mode; desired shutdown time can be set in five-minute increments. The loader includes standard limited-slip front and rear axles for traction in all conditions. Operators can move seamlessly between the joystick and steering wheel. The PowerInch feature maintains high RPMs to maximize hydraulic power and control. The cab of- fers an unobstructed view to both edges of the bucket; a wide window and sloping hood provide clear vision to the rear. Case Construction Equipment; www.casece.com.
