New WR 2500 S Boosts Performance Of Proven WR 2500

The big, new WR 2500 S Road Reclaimer and Soil Stabilizer from Wirtgen America, Inc. is a next-generation successor to the proven Model WR 2500. The "S" in the WR 2500 S stands for "Super", because the WR 2500 S is a beefed-up, higher performing version of the existing WR 2500. In addition to its high performance as a full-depth base recycler of failed road pavements and as a soil and base stabilizer, like its predecessor, the WR 2500 S when equipped for foamed or expanded asphalt can be used to make a foamed asphalt-stabilized base, with significant savings and base performance improvements for the owner and contractor.

Among the improvements of the WR 2500 S over the WR 2500:

• A new fuel injection system in the 12-cylinder Mercedes engine boosts engine power from 455 to 500 kW (610 to 670 hp). The engine now meets EPA Tier II regulations.
• A redesigned, reinforced cutter drum housing includes multiple wear plate inserts to minimize wear. The cutter drum has been redesigned to include bolt-on end rings, which are easier to service.
• Cooling air routing has been reversed, improving cooling performance, operator comfort, and ambient particulate levels. The engine now rests in a newly enclosed compartment. And a new dual-cyclonic air precleaner will result in an extended service life for the air filtration system.
• Exhaust emissions are redirected toward the rear of the machine and away from groundsmen.
• The operator's compartment has a larger air conditioning capacity, with increased visibility despite a reduced glass surface area. A second seat has been added. And the ergonomic control panel has been redesigned, including a height-adjustable, multifunction computer graphics display which helps the operator visualize and control functions such as steering, drum door position, and emulsion injection system.
• The area work lighting system has been placed in a bar integrated with the operator's compartment roof for a cleaner and safer performance.
• Its diesel engine powers a 96-inch-wide by 20-inch-deep cutting rotor, making it a true, high-horsepower deep-cutting heavyweight. Its two-frame design allows the WR 2500 S to retain the very important "floating hood" concept, allowing an expanded volume of material to pass freely through the process without creating a "friction brake" effect on the cutter and cutter drive components.
• Material size is controlled by using hydraulically adjustable, manganese-lined breaker bars that can be remotely adjusted by the machine operator to tighten or close down the area between the rotating cutter and the impact bars, a scheme used for decades by the aggregate crushing industry.
• Its Type III holder system allows quick and easy replacement of broken or worn-out cutter bit toolholders without the inconvenience and added cost of a cutting torch and welder. Drum rebuilding can be executed in one day by two workers without removal of the cutter.
