Top 25 Rollouts of 2011
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.
Volvo Construction Equipment
Volvo says its L250G wheel loader is the first wheel loader specifically designed to fill triaxle, on-highway trucks in only two passes, which means up to 30 percent more trucks can be loaded per day. The machine is powered by a Tier 4-Interim-certified engine with OptiShift transmission for enhanced fuel savings. Additional features include an adjustable declutch, electro-hydraulic controls, oil and fuel filters in one location for easy maintenance and less downtime, and a reverse camera. CareTrack is provided as standard equipment, free for three years.
Case Construction Equipment
Case’s 207-net-horsepower CX300C excavator features Tier 4-Interim-certified cooled exhaust gas recirculation technology. Its new Intelligent Hydraulic System technology is said to reduce total fuel consumption and improve performance. Swing Relief Control technology manages the hydraulic power allotted at the start of the swing operation, and Spool Stroke Control creates an automatic pressure adjustment during digging operations. The machine offers up to 6 percent more lift capacity than its predecessor and has an operating weight of 65,900 pounds. A rearview camera feeds video to a 7-inch LED monitor to expand the operator’s view around the machine. An in-cab auxiliary hydraulic setting system features a new option for 10 memory-recall settings to make tool changes quick and easy for operators.
