The PC performance with 806MHz processor and 256MB SDRAM is designed to significantly speed up data collection in the field. The FC-250 also has a built-in Bluetooth modem and wireless LAN capability as standard features. Topcon also has released SurveyMaster Lite, a new CAD-based desktop application for surveying and job site information editing and plotting. It allows users to manage data from raw format all the way through to a finished plot. Survey calculations can be completed and uploaded to the field collector for stakeout and field verification.

Doosan C 185 portable air compressor

Doosan Infracore Portable Power’s new portable air compressor, the compact Ingersoll Rand C185 compressor, produces 185 cubic feet per minute (cfm) at 100 pounds per square inch (psi), runs off a high-performance 49-horsepower Kubota diesel engine and has an eight-hour runtime. The compressor weighs 1,835 pounds, has two service air ports for multi-tool use and a cool-box design that enables cool air to enter the rear of the compressor.

Super efficient new sweeper

Elgin Sweeper has introduced the Crosswind NX regenerative air sweeper, equipped with the patented NX filtration technology introduced on Guzzler industrial vacuum loaders by Federal Signal in 2002. The sweeper incorporates vertically oriented filter bags, which provide high efficiency filtration of 99.997 percent at 0.5 micron.

Trimble updates portfolio

Trimble has updated its portfolio of mapping and GIS field and office software products, enhancements that focus on impoved Global Navigation Satellite System (GNSS) accuracy for data collection. The DeltaPhase technology, results from receivers such as the GeoXT handheld and GPS Pathfinder ProX show 50-centimeter accuracy in good environments and improved yield under canopy and in multi-path prone areas. Results for the Juno series handhelds with post-processed accuracy are now in the 1- to 3- meter range. The company also has introduced a new version of its Trimble 4D Control software that combines GNSS and optical technologies for real-time deformation monitoring applications.

BID LIST: Pavers

With the 8-foot-class AP500E wheeled and AP555E tracked asphalt pavers, Caterpillar has brought larger-paver technology and features to the commercial paving market. The material-handling system uses four individual pumps that enable each conveyor and auger to deliver the exact amount of mix to the screed. The left and right conveyors and left and right augers are controlled independently, ensuring mix demand is met when shifting paving widths. When equipped with the AS2252C screed, the AP500E and AP555E operate at 33,715 and 35,290 pounds respectively.

Dynapac’s F1000T rubber-tracked, 10-foot paver offers simple, operator-friendly controls that are grouped for convenience. The controls offer a multi-function display, paving speed control, and a single-lever speed control for forward and reverse. The F1000W wheeled, 10-foot paver is scheduled for production beginning this month, and two 8-foot pavers are scheduled for 2011 — the F800T rubber-tracked paver in January, and the F800W wheeled paver in April.

The Wirtgen SP 15 slipform paver for offset concrete paving has a maximum paving width of 6 ft., maximum barrier/parapet placement height of 4 ft., 3 in., and weighs 27,500 lbs. It has quick on-site changes for left or right side pouring and all-track steering and positioning. The Eco mode feature matches engine rpm to machine power requirements.

Available in North America only, beginning in Summer 2010, the Wirtgen SP 25 slipform paver has a maximum paving width of 12 ft., and maximum barrier/parapet placement height of 6 ft. It also features quick on-site changes to left or right side pouring and Eco mode. Its maximum weight is 39,600 lb. (18,000 kg).

The 1448 Plus and 1648 Plus Gehl Power Box Asphalt Pavers feature fully-extendable screed extensions. A full-floating, adjustable and vibratory 8-foot, 13-inch screed is standard on both Power Box models. Crown, invert and pitch adjustments are provided through screw-type jacks located at the center and ends of the main screed assembly. To heat the screed, the 1648 Plus uses a propane burner system. By preheating the screed, asphalt is prevented from bonding to the screed’s wear plate and scoring mat finish. The 1448 Plus uses the engine exhaust to heat the screed with propane-heated screed as optional.
