Engine reduces particulate matter by 90 percent

Komatsu America Corp. has introduced its new diesel engine that features the next generation of engine technology designed to meet U.S. EPA non-road Tier 4 interim emission regulations. The new diesel engine reduces exhaust gas particulate matter (PM) by more than 90 percent when compared to current Tier 3 levels, says the company. It also reduces NOx by more than 45, according to Komatsu. Computer-controlled heavy-duty HPCR system delivers a precise quantity of pressurized fuel into the engine combustion chamber using multiple injections to achieve complete fuel burn and reduce exhaust emissions.

Doosan air compressor: less noise, more fuel efficiency

The new Platinum Series P185 portable air compressor from Doosan Infracore Portable Power is powered by a high-performance 48-horsepower Interim Tier 4 compliant John Deere or Yanmar diesel engine and provides 185 cfm at 100 to 125 psi. The noise level for the new air compressor has been reduced by 50 percent and fuel efficiency has been increased by 21 percent, providing a 10-hour full-load runtime on one tank of fuel. The new Platinum Series P185 portable rotary-screw air compressor launched in California and then launched nationally.

Grinds centerline and shoulder rumble strips

Thomas Grinding’s TR-2000-SC high-production rumble strip machine allows the user to grind both shoulder rumble strip and centerline rumble strips and is capable of production rates of 130 feet per minute (1.5 miles per hour) in asphalt. (Production rate is affected by the hardness of asphalt and other job conditions.) The machine also easily detaches from the tow vehicle.

BID LIST:  Milling machines

The new Wirtgen W 200 and W 210 cold mills can both be equipped with milling drum assemblies of 59, 79 or 87 inches. Three selectable engine speeds enable a broad range of applications, from fine milling, to large-scale surface course rehabilitation, to complete pavement removal at full 13-inch cutting depth. A single engine that generates 550 horsepower powers the 59,934-pound W 200. The 62,138-pound W 210 features a unique fuel-saving drive concept using two diesel engines, which generates a total 671 horsepower.

Road-Ready road milling drums from Kennametal feature Pro-Fit and Quick-Change block systems that are balanced to reduce machine vibration with end rings that reduce wear and provide a straight cut. Every drum is issued with an ID plate, serial number, and certificate of authenticity that authenticates the owner to a Kennametal drum warranty, set of premium start-up tools and a complete maintenance tool kit. Five different types of drums are available: Standard milling, reclamation/stabilization, profile milling, micro milling, and specialty drums.

The BM 2000/50 and BM 2000/60 cold planer milling machines from Bomag offer a 79-inch cutting width to remove a half lane of road surface in one pass. Both planers are powered by EPA Tier 3 compliant Deutz water-cooled diesel engines. The BM 2000/50 features a 469-horsepower engine that delivers a horsepower-per-cutting-tooth ratio of 2.8 and maximum working speed of 112 feet per minute (fpm). The 590-horsepower engine on the BM 2000/60 provides a horsepower-per-cutting-tooth ratio of 3.5 with a maximum working speed of 98 fpm. Both models are capable of milling depths up to 12.6 inches.

Low center of gravity, a wide stance and exclusive double parallelogram rear suspension all combine to deliver more sure-footed operation and improved traction for the Terex PR330 utility mill. Machine design offers a number of configurations to meet application demands including four-track or four-wheel drive systems, and a multi-width cutter offering 24-, 36- and 48-inch cutting widths to maximize machine utilization. The PR330’s “center mount” cutter design positions the full weight of the machine over the rotor. Four steering modes offer exceptional onsite maneuverability.
