Godwin Pumps marked its 40th anniversary with the introduction of two new pumps, the HL260M and CD500M Dri-Prime Pumps. The first pump is a 10-inch by 8-inch automatic priming pump that offers solids handling up to 2 inches in diameter and maximum flows of 4,760 gallons per minute. The larger unit is 24 inches by 18 inches and can handle solids up to 4 inches in diameter with flow rates up to 13,500 gallons per minute.
Cummins Inc. debuted the QSX11.9 and QSX15 Heavy-Duty engine duo featuring its proprietary Xtra-High Pressure Injection fuel system and a variable geometry turbocharger. The 11.9-liter and 15-liter QSX are supplied as fully integrated air-intake-to-exhaust aftertreatment systems to meet 2011 EPA Tier 4 Interim and EU Stage IIIB regulations. The engines use a Cummins Particulate Filter to reduce particulate matter emissions by more than 90 percent and a cooled exhaust gas recirculation (EGR) system to reduce NOx emissions by 45 percent. The engines are said to lower operating costs with up to 5 percent improved fuel efficiency compared with Tier 3, depending on the duty cycle.
Truck body extends life, lowers costs
Caterpillar developed a new hardened steel Quarry Body for the Cat 770, 772, and 775F rigid-frame trucks to extend wear life and decrease cost per ton in appropriate applications. The truck body features 400 Brinnell steel, which resists abrasion and provides superior durability without additional weight or liner systems. It is designed to handle low- to medium-density materials that have low to medium abrasiveness, including limestone, some sandstones, and slate. The Quarry Body is ideally suited for limestone quarries where oversize stone is no larger than 2 to 3 feet in diameter. Its flat floor configuration allows the operator to meter loads when feeding crushers and retains the load well when hauling on roads with grades in the 8- to 12-percent range.
Portable crusher line
Hartl Powercrusher presented its new Powercrusher Series of track-mounted crushers. The mid-size PC3 and PC4 and large PC5 and PC6 units are suitable for processing of virgin aggregates. The PC3 is an impact crusher, while the PC4 is a similarly sized jaw crusher. Both feature low total weight and quick set-up — in less than 30 minutes — and can process up to 300 tons per hour, depending on material and feed size. The PC5 is a larger impact crusher and the PC6 is the equivalent jaw. The units offer a double-deck, independent, heavy-duty grizzly section before the materials enter the crushing chamber. The units can produce up to 400 tons per hour.
Liebherr exhibited the R 9100 mining excavator, a new 100-ton unit powered by a new Liebherr V12 diesel engine. With a rated power output of 757 horsepower, the engine — together with the hydraulic system — supplies high breakout and digging forces for day-to-day operation. The 6.8-cubic-meter bucket is designed for mining, with a design for improved penetration and high fill factor. The cab boasts a raised operator’s seat with large, panoramic windows and two cameras feeding a 10.5-inch display screen. The prototypes are undergoing factory and field testing.
John Deere Power Systems (JDPS) displayed its entire Interim Tier 4/Stage III B diesel engine lineup and announced engine models and power ranges at Bauma. For engines 56kW (75 horsepower) and above, John Deere will use its PowerTech Plus Tier 3/Stage III A in-line, four- and six-cylinder engine platform — which includes cooled exhaust gas recirculation (EGR) for NOx control — and add an exhaust filter for reducing particulate matter (PM). Engines between 56 kW and 129 kW (173 horsepower) will be available in 4.5L and 6.8L displacements and will be equipped with either a wastegate or variable geometry turbocharger, depending on engine size. Engine models 130 kW (174 horsepower) and above include the 6.8L, 9.0L, and 13.5L displacements. John Deere opted not to use selective catalytic reduction (SCR), and noted that it believes its cooled EGR and exhaust filter approach provides OEMs and end-users with “a proven solution with the best total fluid economy.”
After a number of evolutionary changes, Liebherr has christened its new 400-ton payload truck, the T 282 C. The successor to the company’s T 282 B, the unit features a new cast frame, axle box, and cab, as well as a drive system designed and built by Liebherr. Engine options include the MTU DD 20V4000 or the Cummins QSK 78. Its top speed is 40 miles per hour.
