High-volume, mine-duty screen Deister Machine Co. rolls out its BFO-11224-EX2 Mine-Duty Screen. Offering the next generation in machine size and production output, the 12-foot by 24-foot, horizontal, single-deck unit is said to deliver day-to-day reliability and high-volume capacities in a variety of hard rock mining and mineral processing ap- plications. The unit features the new Deister EX Series of geared exciters, which are designed to create the force output required to drive large screens. Geared exciters feature all-steel components, specially-coated bearing inner races to deter wear on shafts, and shafts that are case-hardened and ground for minimal wear. Deister Machine Co. | Aggregates duty loader Case Construction Equipment introduces the Case 1221F wheel loader, the newest and largest model in the company's F Series wheel loader line. Designed with an 11.9-liter Tier 4i engine that delivers up to 355 horsepower, the unit is built for aggregates and mining applications. Enhancements to the engine and transmission at maxi- mum travel speed allow for increases to productivity of at least 18 percent and fuel efficiency of at least 8 percent. The unit is powered by a cooled exhaust gas recirculation engine with diesel oxidation catalyst and diesel particulate filter for clean burning power and more torque than prior models. The wheel loader has an operating weight of 66,800 pounds, with buckets ranging from 6.3 to 7.8 cubic yards. With a 6.8-cubic-yard bucket, the breakout force with tilt cylinder is 55,730 pounds. The machine is available with Z-bar and extended reach configurations. Four programmable power modes save fuel and increase available power. A standard four-speed transmission with manual kickdown offers maximum traction, as well as superior bucket penetration.

Tier 4i excavator Komatsu America Corp.'s PC170LC-10 excavator, with operating weights ranging from 38,100 to 41,5600 pounds, joins its dash-10 series. The excavator is said to improve performance with up to 5 percent more lift ca- pacity with the standard counterweight, while an optional heavier counter- weight offers up to 15 percent more lift capacity than the previous model. The unit offers a net 115 horsepower at 2,100 rpm, but is 10 percent more fuel efficient than its predecessor. All of the system's major components are designed and manufactured by Komatsu, and the integrated design em- ploys a closed center load-sensing hydraulic system that offers efficiency by using both variable speed matching and low speed matching technology. Enhanced working modes are designed to match engine speed, pump de- livery, and system pressure to the application. The SAA4D107E-2 engine provides lower emissions and reduces fuel consumption.
