Description
Fully modular inset slipform paver in the 9 m class
-
The cost-effective 4-track slipform paver stands out due to its enormous variety of applications in large-scale road and airport construction from 2.0 m to 9.5 m wide and 450 mm thick (cannot be combined with all options).
-
The machine concept enables the construction of an exceptionally flat surface.
-
The fully modular machine design, simple changeover and expansion and hydraulic swing arms make the machine highly adaptable to any job site situation.
-
The intelligent, electronic steering and control concept ensures precise handling of the four crawler units and thus precise concrete paving.
-
Precise insertion of tie bars and dowel bars via self-loading dowel bar inserter (optional) enables concrete paving over reinforcing steel.

Features
- WIRTGEN levelling technology: 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.

- Slipform paving inset: 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.
