Wirtgen recently launched a new, specialized soil stabilizer with the ability to crush rocks nearly a foot (300 millimeters) long, such as those found in cobblestone layers or stony soils, and leave homogeneous construction material in its wake. The WRC 240(i) can crush, process, and homogenize materials such as coarse rocks, hard core, and concrete fragments in situ in a continuous process. The layer-processing machine can also add cement and water in the same pass—the latter through its Varioinjection bar—to make base layers.
The WRC 240(i) has a working width of 91.3 inches (2,320 mm), a working depth of up to 20.1 in. (510 mm), and an output of up to 661 tons (600 metric tons) per hour. Wirtgen plans to launch its newest rock crusher in November 2023.
Long-Wearing Wirtgen Components
The WRC 240(i) can bring up to 200 megapascals (29,000 psi) of compressive power to bear on rocks and stones with an edge length of up to 11.8 in. (300 mm). By granulating and mixing soils in place with pre-spread binding agents such as lime or cement, the machine produces quality material more quickly with fewer emissions and resources than a traditional removal and replacement scheme.
The WRC 240(i)’s high-speed crushing and mixing rotor uses large tool bits with impact-resistant carbide cutting edges developed expressly for crushing applications. The bases of its HT18 toolholders are protected by wear-resistant, high-tensile steel. The rotor has edge ring segment protectors and an armored housing and mixing chamber lined with individually replaceable wear plates.
The operator can adjust settings to produce the required grain size and uniformity of the output material. The WRC 240(i) offers nine rotor speed settings, a variable crushing stage, and replaceable mesh screens of varying sizes. The user can set the rotor plate pressure and the distance between the rotor and the mesh, and adjust the crusher’s forward speed for the conditions.
Auto-Steering The WRC 240(i)
The soil stabilizer can use the satellite-guided AutoTrac system to automatically steer its way back and forth at the work site. Starting with a user-specified reference strip and how much adjacent strips should overlap, the machine can take advantage of its working width on every pass. Another technological system, the Wirtgen Performance Tracker (WPT), records working parameters for each construction site for documentation and analysis later.
