Your complete guide to new and updated equipment and supplies in the aggregates industry. by Kerry Clines, Senior Editor Portable frac sand processing CEMCO, Inc. and McLanahan Corp. worked together to produce the industry's first portable frac sand plant, offering an economical and efficient means to produce two sizes of frac sand used in oil and natural gas drilling applications. The plant is easily transported from one deposit site to the next. It is highway legal, meeting all state DOT requirements for transport. Only two operators are needed to assemble and disassemble the plant. Setup takes less than eight hours. CEMCO says the self-erecting plant is designed for high-volume production, offering an average output of 150 tons per hour, and is built for continuous-duty, 24/7 operation. A one-touch screen control panel regulates and determines the operation and characteristic of the entire plant. McLanahan offers training on the system and operation to every customer.

More power, less fuel Komatsu America Corp. says its new WA500-7 wheel loader features a 353-horsepower Komatsu SAA6D140E-6 Tier 4 Interim-certified engine designed to provide increased power while decreasing fuel consump- tion. The loader features an operating weight of 76,611 pounds when equipped with a 7.3-cubic-yard general purpose bucket and has a maximum speed of 22.1 miles per hour. Additional features include Komatsu Smart Loader Logic, which increases engine torque when required; a large-capacity torque converter with lock-up for improved acceleration and hill-climb ability; a new cab design; and easy access for maintenance and servicing.

Next generation excavator LiuGong Machinery Co. says its 922E next generation crawler excavator features additional power and control, a 5-percent improvement in operating efficiencies, and an 8-percent reduction in fuel consumption. The machine's Intelligent Power Control System increases digging force by up to 10 percent for 10-second intervals. The no-time-limit heavy-lift system enables the operator to increase pressure to build force and reduce hydraulic flow to the attachment, while reducing speed. An automatic boom-descent regeneration system allows the boom to descend faster. A multi-working-mode selection system gives the operator the ability to match performance with the job. The excavator is powered by a Cummins QSB6.7 diesel engine rated at 127 kW. Write 52 on reader card. 12 AGGREGATES MANAGER August 2012
