ROLLOUTS Optimized safety, enhanced technology The newest addition to Hyundai Construction Equipment's line of Robex 210, 9-Series crawler excavators is the R210LC-9. It features improvements that include optimized safety, enhanced technology and operator comfort, reduced operating costs, and extended component and wear-part life. The mid-size excavator is powered by a Cummins QSB6.7 water-cooled, four-cycle, low-emission diesel engine with 145 horsepower at 1,900 rpm. At 49,390 pounds, the machine has a dig depth of 18 feet, 7 inches and bucket digging force of 24,900 pound-feet. New steel-tube construction on the cab increases safety and durability. The excavator comes standard with a 7-inch- wide color LCD screen Cluster with toggle switch that allows the operator to select personal machine preferences, as well as power and work-mode selections, self-diagnostics, maintenance check lists, and machine security. Hi-mate, Hyundai's remote management system, provides access to the machine's service and diagnostic information from any computer with internet access. Write 53 on reader card. Powerful, productive, reliable LiuGong Machinery Corp.'s new 877III wheel loader features a 10.8-liter, turbo- charged, electrical-control Cummins diesel engine that is said to deliver extra load-carrying power with its 50-percent torque rise, while keep- ing fuel consumption to a minimum. A hydraulically driven variable- speed fan cools the engine. A double-pump hydraulic system helps reduce energy loss, keeping power strong and consistent at the bucket. Emergency back-up steering is standard. The machine features a ZF auto- matic transmission and limited-slip front and rear differentials for improved control and efficiency. Write 54 on reader card. Powerful, versatile The SK170 is the newest addition to Kobelco Construction Machinery America's Mark 9 excavator series. The full-size excavator delivers up to a 10-percent im- provement in both fuel efficiency and productivity and provides more power and faster engine response. The company says the machine is equipped with the industry's first selective catalytic reduction emission solution for excavators. A new ROPS/FOPS certified cab provides a larger, more comfortable work envi- ronment; a low engine cover and standard wide-angle rearview camera improve operator visibility. The 115-horsepower machine features a fully automatic engine and hydraulic warm-up system that heats the hydraulic circuit to 126 degrees F. Additional features include an operating weight of 38,656 pounds, a bucket dig- ging force of 24,900 pounds, and a maximum dig depth of 21 feet, 5 inches. Write 55 on reader card. Lightweight, powerful breaker Atlas Copco Construction Equipment says its new HB 4100 heavy hydraulic breaker has a service weight of only 9,039 pounds, designed for carriers in the 88,185- to 154,324-pound weight class, but is as powerful as much heavier breakers. Improvements to the breaker include a guide system that makes the breaker more stable and resilient, a new cover plate for the retaining bars that offers more protection in the lower part of the breaker, and increased wear protection at the bottom of the case. The breaker is suitable for secondary and primary rock breaking. Write 56 on reader card. AGGREGATES MANAGER July 2012 13 ROLLOUTS
