39 AGGREGATES MANAGER / January 2017 LiuGong North America's Tier 4 Final excavators, the new E-Series, include the 915E, 922E, 925E, 930E, and 936E. The machines are said to feature best-in-class fuel consumption and a ROPS cab that meets ISO 12117-2 safety standards and is larger than previ- ous model cabs. The cab boasts a nine-position suspension with a joystick module that moves independently for increased comfort and controllability. A standard rearview camera improves operator visibility when traveling. The line is powered by Tier 4 Final turbo- charged Cummins engines. Six selectable working modes optimize hydraulic performance and fuel consumption for specific working conditions. Auto-idle speed function reduces fuel consumption and engine noise when pilot controls are placed in neutral. LiuGong North America | www.liugongna.com Komatsu just introduced the PC650LC-11 hydraulic excavator. With an operating weight between 140,456 and 145,284 pounds, it maintains the productivity and transportability of its predecessor, but improves fuel efficiency, cab design, and serviceability to maxi- mize production while lowering operating costs. Equipped with the latest Komtrax technology, it collects data such as fuel levels, diesel exhaust fluid levels, operating hours, location, cautions, and maintenance alerts, which are relayed to the web application for analysis. A new Operator Identification System reports key operat- ing information for multiple operators, and a new Auto Idle Shut- down feature helps reduce idle time. The excavator is powered by a 436-net-horsepower Komatsu SAA6D140E-7 Tier 4 Final engine. Komatsu America Corp. | www.komatsuamerica.com Volvo's largest excavator for the North American market is the new EC750E. Designed to offer heavy lifting power and high productiv- ity without sacrificing fuel efficiency, the machine can deliver up to 15 percent higher productivity and 5 percent greater fuel efficiency than its predecessor, the EC700OCL. Productivity gains are due, in part, to a more powerful 516-horsepower Tier 4 Final engine. When combined with the larger diameter boom cylinders and increased working pressure, the EC750E delivers a 7-percent in- crease in digging force and a 4-percent increase in hydraulic flow. A new range of buckets, including general purpose, heavy duty, and extreme duty, further increase productivity. The new excavator weighs 3 tons more than its predecessor, but achieves a 5-percent gain in fuel efficiency.
