In offset application, mixer trucks deliver the concrete into the receiving hopper of the slipform paver. Transport to the mould is effected via a slewable belt or auger conveyor. Depending on the paver model, the belt conveyor is available in different lengths and in folding design. The auger conveyor is also available in different designs. And whether belt or auger conveyor: all settings, such as conveying speed, angle of incline or position can be made at the mere push 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 plough. Homogeneous compaction of the concrete is effected by means of integrated electric or hydraulic vibrators. The inset mould forms the concrete slab to the specified thickness and width while the slipform paver advances. In addition, a dowel bar inserter can be integrated 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 transverse to the concrete pavement. The surface is levelled off transverse to the paver’s direction of travel by the oscillating beam. In the next step, a super smoother is used to finish the concrete slab.
WIRTGEN levelling technology controls height, depth and slope to achieve results of maximum precision. In the process, the system continuously reconciles the actual values with a preselected target value, correcting any deviations by means of proportional control. State-of-the-art machine engineering ensures levelling results of consistently high quality while at the same time relieving the machine operator of a significant part of his workload.
WIRTGEN offers customers reliable hardware and software developed in-house. Different systems are used depending on the construction project to be completed and local conditions on site.
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 systems developed 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 motorways 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 right on site and within a short period of time.
Major advantage of the system: it dispenses with time-consuming surveying operations, the installation and removal of stringline or the preparation of a geodetic data model.
