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.

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.
