The new WR 2400 soil stabilizer and reclaimer from Wirtgen Group is a compact machine based on the WR 2000 platform, and fills a gap in the company’s stabilizer/reclaimer lineup.
The WR 2400 provides a working width of 94.5 in. (2.4 m) and is capable of milling and recycling to a depth of up to 20 in. (50 cm), placing it between the 79-in. WR 2000 introduced in 2004, and the 96-in. WR 2500 S and 120-in. WR 3000 S.
When used for soil stabilization, the WR 2400 works its way through the terrain with all-wheel drive and high reserve capacity. For cold recycling, the WR 2400 restores damaged road pavements to stable layers of high bearing capacity by mixing in liquid or powdered binding agents.
With its Tier III diesel engine rating of 563 hp (420 kW), the WR 2400 possesses high reserve capacities for the treatment of difficult soils. The machine has all-wheel drive and features a high ground clearance owing to its vertical lifting column design. This enables the WR 2400 to make headway even in very rough terrain and helps prevent the machine from getting stuck.
The WR 2400 also features four different steering modes. The all-wheel steering system with its four modes enables both the maneuvering of tight curve radii, as well as the parallel approach of curbs or other obstacles.
A technical highlight is the WR 2400’s four-fold, full-floating lifting column system, enabling the chassis to “glide” on the surface smoothly even in case of pronounced bumps. All four lifting columns adapt to the terrain dynamically, thus enabling the smooth behavior, constant working depth and precise operation of the machine.
The WR 2400 offers a full range of cold recycling applications, enabling the various options of in-situ cold recycling to be used in everyday job site methods. The WR 2400 is equipped with microprocessor-controlled injection systems for water, emulsion, cement slurry, or foamed asphalt, which meter the quantities added, thus ensuring an optimum quality of the mix. The spraying nozzles of the different injection systems can be switched on or off individually. Cleaning of the nozzles is automatic.
The milling drum of the WR 2400 is equipped with the quick-change HT11 toolholder system.
As with all recyclers of the new generation, the milling and mixing rotor of the WR 2400 is driven mechanically. This drive concept, which is successful worldwide, ensures maximum efficiency and uses the power of the diesel engine in the best way possible.
A variable mixing chamber ensures constant quality of the mix; the larger the working depth, the larger the quantity of material to be processed in the mixing chamber. This design enables the mixing chamber to increase correspondingly and automatically.
An ergonomic operator’s platform offers maximum convenience and optimal working environment in dusty conditions. The operator’s cabin can be displaced to either side at the push of a button, providing the driver with an optimum view of the milling edge and ensuring precise and safe milling flush to-curb. The operator’s console inside the cabin (driver’s seat and control panels) can be turned continuously by up to 90 degrees.
The steering wheel can additionally be adjusted in height and tilt. The driver’s ergonomic sitting position, the low design of the WR 2400 and the clear view of the operating elements enable the cold recycler to be operated easily and safely.
