The Wirtgen AutoPilot system is used for stringless control of slipform pavers. The system consists of a base station, a tablet computer and the control unit integrated in the paver.
The system eliminates the need for setting up and removing the stringline used for machine control. During use, the machine is guided along a virtual stringline by satellite-aided navigation. This supports the paving of complex geometries such as tight radii or S-bends.
Application
Slipform pavers can be used for paving monolithic concrete structures with the offset method. Curbs, gutter profiles, concrete safety barriers, cycleways and many other profiles can be paved in one piece with wet concrete. Each individual project requires the right slipform mold and process parameters matched to the specific application. Wirtgen slipform pavers offer the paving crew the flexibility and adaptability they need to deliver results in a spectrum of applications.
In offset paving applications, the wet concrete is transferred from the concrete mixer to the slipform mold by means of a feeding conveyor. The concrete in the slipform mold is compacted and molded as the paver advances. The monolithic profile is produced in the desired form at the outlet of the slipform mold. Various parameters can be set to meet the specific requirements of the application and the profile to be paved. With four models, paving widths of up to 4,000 mm, paving heights of up to 3,000 mm and numerous customization options, Wirtgen offers machines for different types of paving projects.

Flexible and Adaptable
The modular concept of the slipform pavers offers numerous combination options. The spectrum of possible applications promotes high machine utilization rates.
Concrete Feeding Systems
A choice of belt and auger conveyors is available for feeding concrete from mixers to the slipform mold. Belt conveyors can transfer large quantities of concrete mix in a short time. Belt conveyors of different lengths and also folding belt conveyors, provide flexibility on the construction site and during transportation of the machines. Auger conveyors thoroughly remix the concrete on the way to the mold and thus prevent segregation of the material. The height, pitch and lateral positioning of the concrete feeding system can be manually adjusted on the conveyor or from the operator’s platform. This means that it can be adapted to the actual conditions on the construction site.
Telescopic Mold Suspension with Quick-Change System
The key component of the paver is the slipform mold. It is mounted on the machine with a height-adjustable and laterally-telescoping suspension that enables it to be brought into the right position. The mold can be mounted on either the left or the right side of all Wirtgen offset slipform pavers. This means that paving can be carried out in the direction of the flowing traffic. Relocating the mold from one side of the machine to the other can be done on the construction site.
Vibration and Chassis Layout
Wirtgen offers a range of different vibration systems for compacting the wet concrete. Hydraulic or electric vibrators can be used, depending on the application and requirements. The combination of both systems can also be used on the same machine.
The positioning of the track units is also extremely flexible. The various models offer a range of different options for setting up the machine on the construction site. Swing legs on the front track units, also known as parallelogram arms, enable alteration of the track spacing and lateral shifting of the center line. Depending on the model, the pavers also feature laterally telescoping rear track units. This promotes machine stability, both on construction sites with limited space and when paving with large offsets between the mold and the machine.
