SP 850 Vario – The all-rounder in road construction
Paving carriageways is the specialty of the SP 850, although its modular design enables the slipform paver to also pave rural roads or special profiles economically in offset or inset application.
Applications in offset paving
Paving paths in offset application
Depending on the number and arrangement of their crawler tracks, Wirtgen slipform pavers are capable of also paving paths and other concrete surfaces in offset application.
Shown here:
- SP 250 on 4 crawler tracks
- Concrete delivery via charging conveyor
- Cantilevering offset mould on the paver's left side when seen in the direction of travel
Machines suitable for this application:
- SP 150
- SP 250
- SP 500
- SP 850 (consult factory)
Paving different profiles in offset application
Offset moulds can be designed in almost any given shape, which allows kerbstones, drainage gutters, cable ducts or special profiles to be fully integrated into their environment or to be incorporated into existing structures.
Shown here:
- SP 500 on 4 crawler tracks
- Concrete delivery via charging conveyor
- Combined profile of traffic parapet and road shoulder
Machines suitable for this application:
- SP 150
- SP 250
- SP 500
- SP 850 (consult factory)
Applications in inset paving
Paving different profiles in inset application
Inset paving is capable of producing any given monolithic profile. Contrary to offset paving, the paving mould is mounted between the slipform paver's crawler tracks.
Shown here:
- SP 500 on 4 crawler tracks
- Concrete delivery via charging conveyor
- Paving a wall for a V-shaped canal
Machines suitable for this application:
- SP 150
- SP 250
- SP 500
- SP 850 (consult factory)
Applications in concrete slab paving
Slipforming rural roads
The concrete pavement is slipformed between the paver's crawler tracks. Space requirements for the job site are kept to a minimum, because Wirtgen slipform pavers have a small loading gauge.
Shown here:
- SP 250 on 4 crawler tracks
- Concrete delivery via charging auger
- Paving a 3 m wide rural road
Machines suitable for this application:
- SP 250
- SP 500
- SP 500 Vario
- SP 850
- SP 850 Vario
Slipforming urban roads
Urban concrete roads can be finished with the super smoother in a final work step of the paving operation, giving them superior riding properties.
Shown here:
- SP 500 on 4 crawler tracks
- Concrete distribution via spreading auger
- Paving a 5.50 m wide road pavement
Machines suitable for this application:
- SP 500 / SP 500 Vario
- SP 850 / SP 850 Vario
- SP 1200
Motorway construction
Wirtgen slipform pavers are extraordinarily efficient when used in motorway construction. Dowel bars and tie bars are inserted into the concrete automatically. The large pavers - SP 1500, SP 1500 L and SP 1600 - are capable of paving concrete slabs across the full carriageway width and in single-layer or dual-layer application.
Shown here:
- Slipform paving train SP 1500 L
- Paving a 11.25 m wide motorway carriageway
- 20 cm bottom concrete layer, 8 cm top concrete layer
Machines suitable for this application:
- SP 500 / SP 500 Vario (single-layer)
- SP 850 / SP 850 Vario (single-layer)
- SP 1200 (single-layer)
- SP 1500 (single-layer)
- SP 1500 L (single-layer or dual-layer)
- SP 1600 (single-layer or dual-layer)
Airport construction
Wirtgen slipform pavers are ideal candidates for the construction of airport runways, taxiways and other traffic surfaces. Finishing beam and super smoother, burlap or texture curing machine can be used in any given combination, ensuring superior functional properties of the completed surface. Further options enable paving on previously laid steel reinforcements, and paving with special profiles.
Shown here:
- SP 1600 set up for a paving width of 10 m
- Wireless levelling control
- Concrete distribution via spreading plough
- Paving parking areas at Amsterdam's Schiphol Airport
Machines suitable for this application:
- SP 500 / SP 500 Vario (single-layer)
- SP 850 / SP 850 Vario (single-layer)
- SP 1200 (single-layer)
- SP 1500 (single-layer)
- SP 1500 L (single-layer or dual-layer)
- SP 1600 (single-layer or dual-layer)
Slipforming track profiles in railway construction
Wirtgen slipform pavers are eminently suitable for producing track profiles in railway construction, such as the so-called "slab track", because they are capable of processing dry concrete mixtures. This method requires the production of a concrete profile that will later accommodate the rails, and is used for the construction of all types of railway lines, from tram to high-speed train.
Shown here:
- SP 500 on 4 crawler tracks
- Concrete distribution via spreading auger
- Paving the track profile for a high-speed train
Machines suitable for this application:
- SP 500
- SP 850
Paving hydraulically bound base layers
Slipform pavers are ideally suited for economically efficient paving of hydraulically bound base layers. A special device allows them to cut pre-determined breaking points during the paving operation.
Shown here:
- SP 850 on 4 crawler tracks
- Concrete distribution via spreading plough
- Dual-lane hydraulically bound base layer forming the subgrade of a track profile for high-speed trains
Machines suitable for this application:
- SP 500
- SP 850
- SP 1200
