Flexibility During Inset and Offset Concrete Paving
Wirtgen will be showing two extremely adaptable machines for concrete paving, the SP 94i and the SP 15i. The SP 15i enables flexible positioning of the slipform paving mold, which is an enormous advantage when producing monolithic profiles in the offset process. The machine also features an extendable operator’s platform that provides a better overview of the working area and the paving results. The machine can also be remotely controlled with the specially developed AutoPilot 2.0 control system. The SP 94i is a fully modular inset slipform paver in the 30 ft class. The 4-track paver with the TeleMold system, which enables fast and flexible variation of the paving width by up to 3 ft on each side – i.e., a total of 6 ft – will be exhibited at the show in Las Vegas.
Innovative Cold Milling Technologies
The Mill Assist machine control system increases process efficiency during cold milling applications. In automatic mode, the system strikes the most favorable balance between performance and operating costs. The power management system automatically adjusts the engine speed and the milling drum speed to deliver the actual power required for each situation. The lower speed range enables a significant reduction of fuel consumption and pick wear. The upper speed range enables the achievement of an optimal milling pattern, even in the case of higher area performance rates. The operator can also preselect one of three working strategies: “ECO,” “performance-optimized,” or “milling pattern quality.”
Wirtgen Performance Tracker (WPT) enables precise and reliable documentation of the milling performance. WPT uses a laser scanner to determine the cross-sectional profile to be milled. The surface milling performance and milling volume are then precisely determined using GPS positioning and other sensors. The most important information is displayed on the machine’s control panel. An automatically generated report can be sent to the machine’s owner by e-mail. This reduces the time, effort, and costs required for the completion of the project.
Cold milling expert Tom Chastain from Wirtgen America will be providing more detailed insights into established milling and profiling practices and technologies in the course of the Conexpo Education Sessions on March 16, 2023, in West Hall 208 – 210 in the Las Vegas Convention Center.
