Wirten’s large but compact milling machine, shown here with the optional canopy, is available in three selectable engine sizes.
The new W 200 asphalt cold milling machine from Wirtgen America Inc. is a large but compact milling machine that can be equipped with milling drum assemblies of 59, 79, or 87 in. (150, 200 or 221 cm) working width. Three selectable engine speeds enable a broad range of applications, such as large-scale surface course rehabilitation, complete pavement removal at full depth, fine milling, and many others. It has a milling depth of 0 to 13 in. (0 to 33 cm) and is powered by a single engine generating 550 hp (410 kW). Its operating weight is 59,934 lbs. (27,185 kg) with half-full water tank, half-full fuel tank, a 165-lb. driver, and tools.
Like the W 200, the new W 210 is a large but compact milling machine, which can be equipped with milling drum assemblies of 59, 79, or 87 in. working width. But unlike the W 200, the W 210 boasts a fuel-saving drive concept utilizing two diesel engines, generating a total 671 hp (500 kW) with both engines engaged. Like the W 200, it features three selectable engine speeds to enable a broad range of applications. Its operating weight is 62,138 lbs. (28,185 kg).
The Parallel-to-Surface (PTS) technology used on the W 200 and W 210S automatically keeps the cutter housing level as they move into a cut, accelerating production, and their “smart” WIDRIVE technology offers new microprocessor-controlled enhancements to machine control systems, tying all main functions to a single source to manage fuel costs, tooth costs and other variables.
The Intelligent Speed Control system incorporates an electronic flow divider that makes the four tracks work in harmony when turning a radius. Skipping and notching are eliminated, track wear is minimized, and the machine operates smoother, according to the manufacturer.
The units incorporate the Level Pro, Wirtgen’s existing automatic leveling system, which is user-friendly and regulates the pre-set milling depth and actual readout electronically.
Asphalt and concrete milling is one of the most abrasive environments for any machine, but the vacuum cutting system will remove dust, fines and smoke from the cutter chamber and extract it out of the conveyor, keeping the machine cleaner and prolonging component life, according to the manufacturer.
And Wirtgen’s new 3DS flexible application drum speed system will automatically slow drum speeds in deep cuts, saving on fuel consumption and tooth wear.
