August 2008 – RollOuts
Cooler conveyor motors
WEG has developed a new control regimen for totally enclosed, fan-cooled induction motors that are used to drive conveyor belts. The company says the new regimen enables a standard TEFC motor powered by a WEG variable speed drive to operate at a much cooler temperature across its entire speed range, especially at low speeds where the integral fan no longer provides efficient cooling.
On demand power blast
Kobelco has introduced the new 66,800-pound, 197-horsepower SK295LC Mark 8 excavator. It sports a new Tier 3 engine and a Power Boost system that kicks up breakout force by 10 percent on demand.
Most powerful breaker
Atlas Copco says the new HB 10000 is the most powerful unit in the company’s line of hydraulic breakers. The new breaker weighs 10 metric tons, measures 9.5 feet high, and delivers 50 percent more impact energy than the company’s next largest unit, the HB 7000. Suitable for carriers in the 85- to 140-metric ton class, the HB 10000 accepts hydraulic flow of 119 to 140 gallons per minute and delivers up to 380 blows per minute.
New short-swing excavators
Hitachi has introduced two new 54-horsepower short-swing excavators, the 17,743-pound ZX75US-3 and the 18,821-pound ZX85USB-3. The ZX75US-3 has a standard boom while the ZX85USB-3 has a swing boom. Both feature two working modes to match engine output to work demand.
Semi-mobile scalping trommel
Titan Equipment has rolled out its new Quick Set-up, semi-mobile scalping trommel. The modular unit is available in various forms for the quarrying and recycling industries. Capacities range from 250 to 1,000 tons per hour.
Sound amplification earmuffs
Howard Light has introduced a new ultra-slim sound amplification earmuff specifically designed for use in intermittent and impact noise environments. The slim design of the Impact Sport earmuffs makes them more comfortable for long-term wear, and patented electronics amplify sound to 82 dBa while also protecting against hazardous noise, says the company.
Eliminates blind spots
ASA Electronics has rolled out a new line of Voyager heavy-duty observation systems to eliminate blind spots in mobile construction equipment. Voyager Observation Systems come with a variety of camera and monitor options, including heavy-duty and waterproof models.
