The satellite-based WPT - WIRTGEN PERFORMANCE TRACKER serves the purpose of measuring and documenting machine performance on the site during ongoing construction projects. The measured data are continuously analysed and displayed to users in a clearly laid out form. WPT directly delivers valuable information about the construction site and, over time, can contribute to the improvement of productivity, efficiency, quality and sustainability on each individual construction site. At present, WPT is available for all current compact and large milling machines from WIRTGEN and the models of the WR series.
WPT for cold milling machines uses a laser scanner to measure the cross-sectional profile to be milled. Surface milling performance and milling volume are then precisely measured using GNSS positioning and other sensors. At the same time, Performance Monitoring in the Operations Center even allows the measured data to be clearly displayed in real-time during the ongoing process. In the case of WPT for WR series machines, all relevant site information, such as the working width and depth, the area and distance worked, fuel, water, and binding agent consumption etc., is registered by means of GNSS positioning and high-precision sensor systems on the machine. This makes it possible to show exactly where and how much binding agent or water was added and, in turn, the respective mixing quality. A detailed final report enables exact documentation of the mixing performance, the quality of the work and the efficiency of the process at precisely defined locations.
A control panel provides the machine operator with a continuously updated overview of all relevant job data. After confirmation by the machine operator, e.g. at the end of a day’s shift, the report is sent to the machine owner by email in Excel and PDF format.
