Rollouts: January 2013
Komatsu’s new WA470-7 wheel loader is powered by a Komatsu SAA6D125E-6 Tier 4-interim engine that boasts 272 net horsepower. The machine weighs 52,007 pounds and features a newly designed large-capacity torque converter with Lock-Up, which the company says provides improved acceleration, faster hill-climb ability, a higher top speed, and lower fuel consumption. The Lock-Up function activates in second, third, and fourth gears, giving the machine a maximum ground speed of 23.8 miles per hour. The loader has greater productivity in V-cycle applications because of the increased tractive effort. The faster hill-climbing ability allows it to up-shift gears faster, achieve higher gear ranges, and maintain higher ground speeds when working in load-and-carry applications. The cab’s front glass has been lowered and the dashboard redesigned to improve visibility.

Atlas Copco’s new Chargetec UV2, a multi-directional ANFO (ammonium nitrate/fuel oil explosive) charging truck, has a high-speed charging capacity of 286 pounds per minute with high density. The single-boom truck is equipped with one or two ANOL CC charging vessels for charging of a full drill pattern with fixed carrier positioning. The charging vessels are available in volumes of 300, 500, 750, or 1,000 liters (carrying capacity of 537, 895, 1,342, or 1,790 pounds). The heavy-duty carrier has articulated-frame steering and four-wheel drive for maneuverability, and it may be equipped with diesel or electric hydraulics.

Rice Lake’s new TradeRoute legal-for-trade onboard scale allows drivers to bypass local truck scales and conduct business directly to and from their payload, printed ticket and all. It operates solely from a parked position where hydraulic power is used to engage the scale. Unlike other onboard designs, TradeRoute’s load cells support the vehicle’s load only during the weigh cycle, eliminating the potential for premature load-cell wear from constant engagement. The scale is designed to install around the frame of many common straight-truck designs using a combination of frame-hugging weigh modules, a stainless-steel junction box, and a weatherproof control center that houses the weight indicator and ticket printer.

The new 655K crawler loader from John Deere was designed using customer input. It features a John Deere PowerTech 6.8-liter IT4 diesel engine that boasts 145 horsepower at 1,800 rpm. The hydrostatic transmission provides customers infinite speed control, power management, live power turns, counter rotation while staying in gear, and dynamic braking. The transmission controls allow operators to pick between V-pattern or joystick options. The Quad-Cool system isolates coolers from engine heat for increased durability. A standard, hydraulic-driven, variable-speed suction fan runs only when needed. Onboard diagnostics include a monitor that provides real-time values for every temperature, pressure, and speed sensor.

Deister announced two new options for use on mine-duty screens — the exciter vibrating mechanism and the isolation base.
The exciter is designed for use with large, linear-stroke screens and feeders. Innovative seal, shaft, and bearing designs are said to make the unit rugged and easy to maintain. The exciter mechanism can be driven by V-belts or a direct-drive flexible shaft.
