SUPPLYLINES 39 AGGREGATES MANAGER / July 2016 Liebherr's R936 excavators are equipped with integrated, perfor- mance-enhancing technology, based on the Positive Control hydrau- lic system with sensors attached at strategic points on the excavator. When the operator moves the machine, the intelligent control for the engine and hydraulic system optimizes each movement, facilitating fast, fluid, and precise working movements. The pump circuits can work independently or together, making optimal energy utiliza- tion possible. Its operating weight is between 30 and 38 tons, and the engine power is 231 horsepower. The R 936 is said to achieve maximum digging and breakout forces for a significant increase in productivity of up to 13 percent over the previous model. Liebherr | www.liebherr.com LiuGong introduces the 925E Series Excavator. The 65,612-pound machine is powered by a Cummins engine and meets Tier 4 Final requirements. The unit has a maximum digging depth of 22 feet, 7 inches. Standard features include six selectable working modes and a multi-functional LCD display with maintenance information that is available in seven languages. Audible alarms provide alerts while safety is also enhanced by a built-in, rear-view camera. LiuGong | www.liugongna.com The 22-ton Volvo EC220E is powered by a Tier 4 Final Volvo D6 engine. The fully optimized hydraulic system and ECO mode deliver the power required to complete a task, while auto engine shutdown helps reduce fuel consumption and emissions. The increased pump power enables responsive operation for greater productivity and cycle times — and with the boom float function, the pump power normally used for boom lowering can be saved or used for other functions, also reducing cycle times. The new valve controls the boom opera- tion proportionally according to the arm operation while grading. This system also improves lifting controllability while traveling simultaneously. Volvo Construction Equipment | www.volvoce.com The TB1140 Series 2 excavator, from Takeuchi, features a pivot boom and standard backfill blade, giving it the functionality of a compact excavator. The hydraulic system, dual auxiliary hydraulic circuits, and proportional auxiliary hydraulic controls are said to make it suitable for a range of hydraulically controlled attachments. With an operating weight of 34,116 pounds, it has a maximum digging depth of 18 feet, dump height of just over 20 feet, and maxi- mum reach of nearly 29 feet. The excavator has a bucket breakout force of over 22,000 foot-pounds. Powered by an Isuzu engine, the 103.3-horsepower unit can travel up to 3.3 miles per hour.
