March 2008 – RollOuts
Clean water, immediately
Clearwater Industries designed the Portable Water Clarifier to help aggregate producers, dredgers, and others immediately recycle and reuse water. The company says operators can take a dirty water stream and produce clean water immediately, concentrating the fines or solids to a thick state, eliminating the need for clean water ponds or setting ponds. The totally self-contained unit can deliver up to 2,000 gallons per minute at 20-percent solids by volume.
New excavators debut this month
Hitachi is introducing two new excavators at this month’s ConExpo-Con/Agg show, including the reduced tail-swing Zaxis 135US-3 and the new wheeled excavator, the Zaxis 220W-3. Both machines feature Tier 3 engines and the company’s new CRES II cab, which is bigger and has more glass area that previous cabs. Both are more powerful than the models they replace and travel at faster speeds. The Zaxis 135US-3 also has faster arm roll-in and boom lower/arm movement due to hydraulic refinements, and the Zaxis 220W-3 has more stability for moving Jersey barriers without outriggers.
Pumps lots of water, fast
Multiquip says its new InstaPrime pumps move large quantities of water quickly. Ranging from 6 to 12 inches in size, the pumps can move up to 5,000 gallons per minute and are recommended for dewatering, sludge, sewer-by-pass and well-point jobs.
