AGGREGATES MANAGER / January 2018 7 Intelligently controlled drill rigs Atlas Copco unveils its newest drill rigs in the SmartROC series, the D50 and D55. The rigs are powered by low-emission engines, which adapt their output to the task at hand at all stages of production. The Rig Control System (RCS) allows for intelligent control of engine RPM and air compressor load for more effective penetration with lower fuel consump- tion and decreased wear on components. Automatic rod handling and uniform feeding also enhance productivity. The D50 is designed to drill holes with a diameter of 3 1/2 to 5 1/8 inches, while the D55 drills a slightly larger diameter of 3 1/2 to 6 inches at depths of up to 148 feet. Atlas Copco | www.atlascopco.com Removes large rocks before screening Lake Erie Portable Screens introduces the Pitbull PB148 Static Grizzly. The new unit pairs with the Pitbull 2300 screening plant and is said to offer an economical option for applications where sorting oversize material prior to screening or crushing is necessary to prevent equipment damage. The griz- zly includes features to allow simple bar removal or adjustments, as well as transportability. Each of the screen's 18 bars are installed with two sets of bolts and nuts driven completely through the bar and support. This saves time during bar adjustment or replacement. The self-cleaning grizzly bars rest on an angle to create a diamond shape and tapered openings to eliminate material becoming stuck between bars. In addition, the grizzly is constructed with standard "D" ring lift lugs for ease of transportating and positioning.

(KPI). The manufacturer says the new industry-standard drop-in carbide wear parts will significantly decrease the downtime required for service and maintenance. The new carbides are estimated to reduce replacement time to approxi- mately 20 percent of what it is with other solutions. They can also be retrofitted into existing VSI crushers from KPI. Kolberg-Pioneer, Inc. | www.kpijci.com Motor grader simulation training pack CM Lab Simulations announces its new Motor Grader Training Pack. Available for deployment on any Vortex simulator, the new pack is pow- ered by the manufacturer's Vortex Studio simulation and visualization software. Designed to bridge the gap between classroom and field work, operators can manipulate and position the simulated blade in the same way as on the real machine, including a functional saddle locking bar and automated cross-slope control. Trainees can progress from basic control familiarization to advanced exercises and are scored on metrics such as blade efficiency, grade quality, idle time, cycle time, fuel con- sumption, and more.
