Automatic 3D control system for SP 15 / SP 15i / SP 25 / SP 25i

WIRTGEN provides customers with AutoPilot 2.0, an innovative and economical alternative system for steering regulation via stringline or other 3D machine control systemsdeveloped in-house.

The system is based on GNSS (Global Navigation Satellite System) and assists with the automated paving of a wide variety of offset and inset profiles, such as concrete safety barriers on highways or curbs for traffic islands. As opposed to conventional 3D systems, the digital data model is created right on the construction site. Even complex profile configurations can be created on the job site and within a short period of time.

The major advantage of the system is that it eliminates time-consuming surveying operations, the installation and removal of stringline, or the need to prepare a geodetic data model.

In offset applications, a concrete mixer transfers the concrete to the receiving hopper. The material is transported into the slipform via a swivel-mounted conveyor belt or a swivel-mounted auger conveyor. Depending on the machine model, the conveyor belt is available in various lengths and in a folding version. Different versions of the auger conveyor are also available. Whether conveyor belt or auger - all of the settings such as conveyor speed, inclination angle, or position can be adjusted at the touch of a button.

In inset application, the concrete is either deposited right in front of the slipform paver or is fed in front of the machine from the side via a belt conveyor or side feeder. In the next step, the concrete is distributed evenly across the full paving width by a spreading auger or spreading plow. Built-in electrical or hydraulic vibrators ensure homogeneous compaction of the concrete. The inset mold forms the concrete surface to the specified thickness and width while the slipform paver travels forward. In addition, a dowel bar inserter can be added which inserts the dowel bars into the concrete as specified parallel to the paver’s direction of travel. Central tie bars or side tie bars can be inserted perpendicular to the concrete pavement. The oscillating beam scrapes the surface across the roadway. Afterwards, a super smoother can smooth the concrete surface.

WIRTGEN’s leveling technology adjusts height, depth, and pitch for extremely accurate results. In the process, the system permanently compares the actual values to predefined target values and adjusts the deviations proportionally. This state-of-the-art machine technology consistently guarantees outstanding leveling results and significantly reduces the machine operator’s workload.

WIRTGEN offers customers reliable hardware and software developed in-house. In this context, a variety of systems are used depending on the construction project and local conditions at the job site.
