Wirtgen WR240i Soil Stabilizer and Cold Recycler
The WR240i is the proverbial all-rounder in the Wirtgen fleet. As a result of its large working width and depth and superior milling and mixing performance, this machine provides maximum flexibility for any type of soil stabilization or cold recycling job.
The WR240i as a soil stabilizer
The finely graded Wirtgen WR240i includes a tailored solution for any soil stabilization and cold recycling job. As a result, these machines are ideally suited to the powerful, large-scale stabilization of ground with insufficient bearing capacity. The stabilization process converts poor-quality soil into a premium construction material. In addition, its perfect ergonomic design and maximum visibility, high engine power and mixing quality, superior all-terrain mobility, automated features and many other highlights make the WR a pioneer in terms of output at low operating costs − regardless of the type of soil stabilization job.
Soil exchange continues to be specified very often even though it no longer represents the state of the art. Working as a soil stabilizer, the WR uses its powerful milling and mixing rotor to mix pre-spread binders, such as lime or cement, into existing soil of poor bearing capacity to a working depth of up to 560 mm, converting it into a premium construction material right on the spot. The resulting homogeneous soil-binder mix offers high levels of tensile strength, compressive strength and shear strength as well as lasting water resistance, frost resistance and volume stability. Typical applications include the construction of paths, roads, motorways, parking lots, sports grounds, industrial parks or facilities, airports, dams, backfills or landfills.
Top-performing cold recycler
Machines of the WR series are not only state-of-the-art soil stabilizers. They are “full liners” offering equally compelling cold recycling features. When operated in cold recycling mode, the WR machines convert asphalt layers in need of rehabilitation to high-quality base layers− regardless of the site area and working depth. Additives and binders used for this purpose include cement, water, bitumen emulsion and foamed bitumen. Perfect job outcomes are ensured by highly accurate metering, a consistently superior mixing quality, the clearly structured, easy operation of the machine and its precise levelling.
Steadily increasing volumes of truck traffic cause structural damage to the different layers of asphalt roads over time, while at the same time reducing their bearing capacity. In recycling mode, the WR eliminates these deficiencies quickly, economically and in a resource saving manner. It is equipped with a powerful milling and mixing rotor and state-of-the-art injection systems. The cold recycler mills and granulates worn-out asphalt pavements, injects binding agents and water in precisely metered quantities and mixes them with the pavement material to be recycled, all in a single machine pass. The new base layers produced by means of this in-situ process are distinctive for their exceptionally high bearing capacity.
A new dimension in ergonomic design and handling
The anatomically shaped driver’s seat with spring and air cushioning is the ergonomic showpiece of the WR series. It can be fully adjusted to different body sizes, guaranteeing a perfect seating position for many hours. In addition, ergonomically designed controls are integrated in both arm consoles – they are arranged within easy reach to enable intuitive operation. All basic machine functions have been grouped together logically in the multifunctional joystick on the right-hand arm console, providing superb ease of use. The entire driver’s seat including arm consoles and steering column can be swivelled through 90 degrees to either side, giving the operator a full view towards the rear of the machine while maintaining a relaxed body posture. The soundproof, spacious WR cabin provides ample room to move, a comfortable interior and pleasant indoor temperatures.
Excellent visibility – day or night
Construction projects are nowadays carried out under tremendous pressure of time with no regard for adverse weather, darkness or night. The intelligent lighting system of the WR overcomes these challenges. It comprises six headlights at the front of the cabin, optionally in LED design, two spotlights each on the left and right side, two curve lights at the rear and two spotlights for flexible mounting by means of magnetic bases to fully illuminate all important work areas around the machine. Operation of the machine can thus continue at full power even at night – and the WR is utilized to full capacity.
Comprehensive camera system
Camera systems are developing into increasingly important support tools when it comes to monitoring the operational processes and procedures of machines where good visibility is a must. The camera solutions available for the Wirtgen WR give the machine operator the additional eyes he needs to view important but otherwise inaccessible work situations. A reversing camera is part of the WR basic on-board equipment package. It can optionally be upgraded to a full equipment package consisting of four cameras installed at various points of the machine. Upon the customer’s request, a system comprising four high-resolution color cameras can be installed at various points of the machine – at the rear of the machine, on the left side of the machine and underneath the machine at the front and rear rotor plates. If several cameras are used, an additional screen is installed to display the camera image.
All-wheel Drive for outstanding all-terrain mobility
Traction is vital when it comes to stabilizing on deep, muddy ground. Extra large, deep-tread tyres very effectively transport the engine’s high drive power into the soil. The powerful All-wheel Drive ensures constant maximum traction of each of the four separately hydrostatically driven wheels. In addition, uniform traction is ensured by the sophisticated weight distribution across the machine frame. The machine’s advance speed is load-dependent and governed by an automatic power control system that dispenses with the need to engage or disengage the differential lock.
