DOOSAN INFRACORE
Rugged excavator
The Doosan DX350LC-3 excavator features a 281-horsepower engine, a 7,603-pound
operating weight, and a 41,667-pound arm digging force. Built for the most rugged con-
ditions, this excavator features significant power and performance increases to go along
with its Tier 4 Interim status. A new boom float option allows the boom to move freely
up and down without hydraulic flow, while a temporary reset button offers the ability to
momentarily disengage the float, allowing hydraulic flow to activate the boom.

KLEEMANN
Tier 4 Final cone plant
Kleemann says its MCO 9i S EVO mobile cone crusher offers high-produc-
tivity secondary or tertiary crushing in a fuel-efficient, Tier 4 Final emissions-
compliant machine. It provides a discharge conveyor-mounted final classify-
ing screen with oversized aggregate return conveyor that permits a closed ma-
terial cycle and production of final particle sizes without a standalone screen.
The oversize can also be discharged via the swivel-mounted return conveyor
at the side. The unit's diesel-electric drive provides low fuel consumption in a compact design. Optional crusher anti-spin and automatic lubri-
cation functions make for high crushing capacities and durability. Its power plant generates 332 horsepower at 1,500 rpm, and the optimized
crusher housing design permits more than 287 horsepower to be continuously available to the crusher. The cone diameter permits a raw feed
capacity of 287 tons per hour, with a feed size maximum of 8 1/4 inches. Kleemann | www.wirtgenamerica.com
JCB
Tier 4 Final loader
JCB debuted the 457 wheel loader with the all-new JCB CommandPlus cab. The
machine is the first to show off the completely new cab structure, engine cover,
and rear counterweight design which are said to contribute to improved visibility,
lower noise levels, increased cab room, and an enhanced working environment for
the operator. In addition, the 457 is the first large JCB wheel loader to meet Tier
4 Final emission standards. An MTU diesel engine contributes to fuel savings of
approximately 16 percent, compared to the previous model. It meets emission
standards without the need for a diesel particulate filter. JCB | www.jcb.com
DEISTER
High-volume screen
Deister Machine Co.'s BFO-11224-EX2 Mine-Duty Screen represents 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 applications. 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.
