Top 25 Rollouts of 2010
Increased production throughput
Unified Screening & Crushing’s new SuperFlow screens are a hybrid of wire cloth and urethane support strips. Each wire is said to vibrate independently to provide a harmonic frequency that reduces plugging and blinding, improving throughput performance by as much as 30 percent. The company says the screens perform well when screening dry material, but are especially productive when handling wet or sticky material. The screens are available in three styles.
Washes aggregate using less water
W.S. Tyler says its new Hydro-Clean washing units clean aggregate while reducing water consumption by up to 75 percent over traditional log washers. The units use high-pressure nozzles rotating at 90 revolutions per minute to spray up to 90-percent recycled water on material with pressures up to 2,900 pounds per square inch, removing silt and clay particles as small as 63 microns and processing up to 400 tons per hour, depending on model size and application. Water consumption ranges from 27 to 211 gallons per minute, depending on application and model size; power requirements are no higher than 300 horsepower (225 kW) on the largest model. The units are available in four model sizes that produce 20 to 400 tons per hour.
Updated loader/backhoe line
Case’s new 590 Super N, the largest loader/backhoe in the company’s N Series, features a 108-horsepower, 4.5-liter, turbocharged engine. The company describes the N Series as “stronger everywhere,” touting increases in backhoe breakout force and lift, along with increased loader breakout force, lift, and reach. A new Power Lift system is said to channel hydraulic power directly to the boom, increasing lift capacity by as much as 39 percent. Three transmissions are available — Powershift S-Type, Powershift H-Type, and Powershuttle. New side lighting illuminates the entire perimeter of the machine.
Tier 4 Interim/Stage IIIB engines
Caterpillar’s five new Tier 4 Interim/Stage IIIB Technology industrial engines — C13 Acert, C15 Acert, C18 Acert, C27 Acert, and C32 Acert — range from 385 to 1,200 brake horsepower, respectively, and are available with an extensive choice of options suited to meet original equipment manufacturer and end-customer requirements across a wide range of heavy-duty applications.
Cardinal Scale’s new low-profile Yukon truck scale is designed specifically for mining and off-road vehicle weighing, featuring a 150-ton capacity with high 70-ton concentrated load capacity. The scale is available in impervious hydraulic or electronic scale types and features extra-wide 12-, 14-, and 16-foot scale platforms.
Matches power percussion to the rock
Atlas Copco’s new ROC T35M drill rig features the COP 1840 rock drill with 18 kW of drilling power to drill holes ranging from 2.5 to 4 inches in diameter to a depth of 82 feet. Powered by a 190-horsepower Cummins QSB 6.7 Tier III engine capable of 2,300 revolutions per minute, the rig matches percussion power and feed to the rock. The unit features a single joystick control and a carousel with rocker switch rotation that can handle up to six, 12-foot rods plus a 14-foot starter rod.
