www.rockproducts.com ROCK products • May 2015 • 7 FAST FACT A m o n g t h e e q u i p - ment showcased was the tier 4 final 1050K Crawler Dozer, and the 300G LC and Hitachi ZX300LC-6 excavators. The 300G LC replaces the 290G LC and boasts 19 percent more horsepower and 17 percent more swing torque and larger hydraulic pumps than its prede- cessor. "The 300G LC hits a sweet spot in the 30-ton excavator market," said Mark Wall, excavator product mar- keting manager, John Deere Construc- tion & Forestry. "It's bigger and more powerful than the 29 ton machine and boasts all the popular G-Series features customers expect from John Deere. This model will greatly benefit those in the underground, road building, ener- gy, commercial building, and pipeline industries." The 300G LC features a 223-hp certi- fied Final Tier 4 John Deere PowerTech PVS 6.8L engine. Operators don't have to worry about diesel particulate filter (DPF) cleaning as it occurs automatical- ly with no impact to machine operation. After extensive testing, John Deere's DPF can go up to 15,000 hours before ash removal. Like its counterparts, the 300G LC features excellent total fluid economy (diesel fuel and DEF). www.unifedscreening.com "Half the change-outs. Half the overtime. Half the cost of stainless steel." That's what Tuffex ™ woven wire screens did for Kraemer Mining & Materials. Kraemer was replacing screens on their 6' x 18' single-deck PEP screens as often as every two weeks. Switching to Tuffex wire from Unifed ® Screening & Crushing gave the Kraemer operation the longer wear life they needed. Tuffex wire is manufactured with a proprietary process that creates a higher tensile strength. Elongated, fne grains in the wire decrease surface rust and corrosion. Tuffex wire provides more ductility and is less susceptible to breakage. Mike Strom says "Tuffex screens cost about as much as high- carbon wire, but deliver much greater savings on change-out expenses. When it was time for our seasonal change-out, we kept the same Tuffex screens. They still looked good and performed very well." Find out how Tuffex wire can save you money.

"Tuffex ™ wire more than doubled our wear life." — Mike Strom, quarry supervisor Kraemer Mining & Materials Burnsville, MN 866-968-3697 info@unifedscreening.com | www.unifedscreening.com The ZX300LC-6 is an improved ver- sion of its popular predecessor – the ZX290LC-5 – and features EPA Final Tier 4 (FT4)/EU Stage IV Isuzu engine technology that meets rigid emission standards. This bigger, more powerful machine gives operators the efficien- cy, reliability and durability needed when out on the jobsite.
