SP 20i

EU Stage 5/US EPA Tier 4f

2,500 mm

0 - 2,000 mm

Cost-efficient and professional offset concrete paving

The four-track offset slipform paver can pave a wide range of monolithic concrete profiles with heights of up to 2.0 m or concrete surfaces at working widths of up to 2.5 m
In particular, large concrete safety barriers, but also kerbs, kerb and gutter profiles, channels, channel drains, narrow roads and pathways and customer-specific special profiles are typical examples of its repertoire.
The machine’s compact dimensions and optimised weight enable easy and economical transportation from site to site.
For maximum paving precision, the machine can be controlled without a stringline with the AutoPilot 2.0 system, developed in-house by WIRTGEN.
The state-of-the-art SP 20 (i) can also be equipped with third party 3D systems using predetermined digital terrain models without any problems.

Slipform paving Offset

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.

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.

WIRTGEN AutoPilot 2.0

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.
