Deep Milling in Light Package

摘要

The W 220 provides the milling width and depth of the company's heavier W 250, but with a lower weight that enables it to more easily meet legal weight load limits, Wirtgen says. The W 220 will mill up to 14 inches deep, at a nominal milling width of 87 inches. Its power plant provides 766 horsepower with an operating weight of 80,160 pounds, and can produce up to 900 tons per hour of reclaimed asphalt pavement (RAP). Unit can remove asphalt layers over a foot deep, as well as portland cement concrete pavements.Jhree different milling drum speeds can be adjusted from the operator's platform: high speed for large-scale milling of thin lifts; medium for standard surface courses; and low speed for optimized fuel consumption and low cutting tool wear.
