Height control (leveling) controls the installation height of the concrete profile in relation to a reference. Traditionally, slipform pavers achieve longitudinal and height control via mechanical probing of stringlines.
However, for some years now, 3D control without stringlines has also been proven to be effective, and in some cases it is already a requirement for the awarding of a project. That is because, compared to control via a stringline, 3D control delivers many advantages – for instance, the ideal installation line is not transferred via a string to the real construction site, rather it exists as a model in the computer. This digital site model helps to define the target positions of the machine, and measurement systems – e.g., the motorized Total Station and Prisma –monitor the actual positions. This makes producing any concrete profiles easy, economical, and precise.
