Top 25 Rollouts of 2011
Kleemann/Wirtgen America Inc.
Mobile impact crushing
The MR 110 Z EVO impact crusher from Kleemann features a new material flow concept — the discharge belt is 4 inches wider than the discharge chute which is 4 inches wider than the inner width of the crusher. The rapid flow of material keeps it away from the critical area under the crusher and reduces wear. Additional features include an independent vibrating double-decker pre-screen and a newly designed crusher bypass that includes changes to its geometry and form to boost performance and reduce wear. Optional new and improved screening units are available and are more than 44 percent larger in size than those on previous units, allowing for tonnages of between 350 and 450 tons per hour.
Screening and Crushing Solutions
World’s largest mobile cone crusher
Screening and Crushing Solutions says its TC1885 is “the world’s largest-ever mobile cone crusher.” The machine is powered by a 27-liter, 875-horsepower, twin-turbo, V12 Caterpillar engine. The crushing unit weighs 71.7 tons on its own. The closed-side setting can vary from 65 millimeters down to 15 millimeters. Four concave options are available with feed openings of 19.7, 14.2, 9.4, and 7.1 inches. The crusher, originally manufactured for a mining and demolition company in Australia, will be available globally.
Eliminates repair costs, downtime
Mettler Toledo’s VTS101 truck scales use a Powercell PDX load cell technology that eliminates the typical maintenance, repair costs, and downtime related to conventional vehicle scales. The VTS101 consists of a steel deck supported by orthotropic ribs that are sealed from the elements by automated continuous welds. The company says the Powercell PDX load cell provides predictive diagnostics, including automatic notification of weighing errors, overloading, environmental conditions, network health, load-cell voltages, and enclosure integrity, without the need for maintenance-prone external converter boxes.
Telsmith, Inc., an Astec company
Automatically adjusts feed rate
Telsmith’s Tel-Trax Model TC52 high-capacity, track-mounted cone crushing plant is built around the 400-horsepower model 52SBS cone crusher. The plant boosts tonnage output in secondary and tertiary applications, while accepting larger feed (up to 12-inch topsize) than 300-horsepower units. The unit is outfitted with automation controls that automatically adjust the feed rate and reduce the need for operator oversight by monitoring parameters such as crusher overload, feed-bin levels, diesel power supply, and the discharge conveyor. The automated controls package also allows a soft link to additional Tel-Trax crushing and screening plants to provide a completely linked and integrated processing solution.
Load-sensing hydraulics, increased power
Major improvements to Caterpillar’s 980K wheel loader include a new cab, load-sensing hydraulics, a 25-percent increase in lift force, and a 16-percent increase in tilt force over its predecessor, the 980H. The machine also features new electro-hydraulic steering with joystick or steering wheel control, Performance Series Buckets, and an optional lock-up torque converter. The machine is equipped with the new Tier 4-Interim Cat C13 ACERT engine with peak net power of 369 horsepower at 1,500 revolutions per minute. The loader accommodates buckets ranging in size from 5.25 to 16 cubic yards.
Doosan Infracore Construction Equipment America
Doosan’s 301-horsepower DL450 wheel loader boasts a robust Z-bar lifting system that provides a breakout force of 53,572 pounds. Additional features include a quiet, comfortable cab and easily accessible maintenance points. The machine is available with buckets ranging in size from 4.5 to 6.3 cubic yards.
