Level control using a 3D system
With stringless systems, the computer of the 3D control system feeds the paver’s control system with the specified parameters of level and horizontal position of the concrete profile to be built. The 3D system uses a special interface to communicate with the controller of the slipform paver.
Two prisms are typically installed on the slipform paver which have direct visual contact to a total station each, reflecting their optical beam. The total station keeps determining the prism’s current 3D position. The measured results are transmitted by radio to the system computer on the paver. Two multi-axial slope sensors integrated in the machine additionally determine the paver’s longitudinal and cross slope.
