40 • ROCK products • July 2018 EQUIPMENT & TECHNOLOGY LOADING & HAULING For greater safety and efficiency, Epiroc released a number of automation fea- tures for the Scooptram underground loader. The Scooptram Automation Regular package allows the loader to be controlled through an operator station from a remote location. "With the new Scooptram Automation Regular package, the operator can control the loader from a safe stationary or mobile control station, even while the loader is out of sight," said Clint Byington, busi- ness line manager – underground rock excavation, Epiroc U.S. "The automation package also makes it possible for our customers to quickly and easily transition from manual to automatic mode, which is crucial in mines with a dynamic environment or quick advancements," Byington added. To minimize environmental impact and keep personnel out of harm's way while production proceeds quickly and smoothly, automation is key. Pro- duction and the efficient utilization of machinery can continue even during shift changes and when personnel are not safely permitted in the work area; for example, when the mine has not yet been adequately ventilated or when there is a substantial risk of fall- ing debris after blasting. The operator can make swift transitions from manual to automatic to quickly adapt to the sit- uation at hand. "The Scooptram Automation Regular package allows our customers to auto- mate a single loader without having to spend lots of time and money making extensive infrastructure alterations," Byington said. The automation package includes cameras, sensors and safety modules that are mounted onto the Scooptram as well as a safety system that can be easily installed in the mine. If a person or another machine should enter the Scooptram's work vicinity while the safety system is enabled, the Scooptram will automatically shut down to avoid causing potential harm. Epiroc, Liebherr PR 776 World's First Hydrostatically Powered Dozer Liebherr USA Co.'s new dozer, the PR 776 Generation 6, debuted at the 2018 Elko Mining Expo. The new PR 776 is powered by a Liebherr 12-cylinder diesel engine developing 768 hp/759 hp. It has a maximum operating weight of 161,354 lb. and is equipped with blade capacities of 23.5 cu. yd. (semi-U blade) or 28.8 cu. yd. (U blade). A new feature is the hydrostatic drive. The modern drive concept automatically adjusts speed and torque, optimizing the transmission of the engine power to the tracks as load changes. This pro- duces exact and powerful steering, and track slip is minimized allowing opera- tors to focus completely on their work. The intelligent Liebherr engine-man- agement system combined with the Liebherr Power Efficiency System and the new hydrostatic drive allows Liebherr to master and optimize all equipment systems and processes to maintain constant engine speed, increase overall machine efficiency and reduce fuel consumption. This differen- tiates Liebherr's travel drive concept from other drive concepts available on the market, and comes standard in all Generation 6 Liebherr dozers. With an optional GPS navigation system, the work progress and surrounding area can be visualized, increasing machine productivity and minimizing operator stress and strain. Pendulum-mounted guide wheels and track rollers ensure excellent chain traction and signifi- cantly reduce equipment vibration. The ECO function is also standard. It allows operators to choose between high performance and maximum effi- ciency. The ECO control system enables greater travel drive efficiency in light to medium operations, and also provides greater fuel savings. All of these measures, according to the manufacturer, lead to significantly lower fuel consumption than the indus- try standard with similar pushing performance. Centrally located maintenance points, access flaps and engine compartment doors that open to a wide angle, a tilt- ing cab as standard and, as an option, a radiator fan that can be swung out for cleaning are all features that speed up and simplify servicing work. The PR 776 has exceptionally long change intervals for operating fluids such as hydraulic or engine oil. Depending on the nature of the work, and provided that regular checks are performed, the change interval for Lieb- herr-plus oils can be as long as 8,000 hours of operation.
