The full-floating lifting-column system in the Wirtgen WR 2400stabilizer/recycler enables the machine to glide evenly on uneven surfaces. Because the four columns adapt to the terrain dynamically, says Wirtgen, the machine can maintain a constant working depth and has an enhanced capability to resist bogging down. The 563-hp machine has a working width of 94.5 inches and is capable of milling and recycling to a depth of 20 inches.
