Secondary lining
formwork trolleys.
Steel formwork, working platforms and travel arrangements configured around your tunnel section and construction sequence.

The tunnel profile.
The working space.
The pour sequence.
A secondary lining trolley brings the concrete formwork and working access together in a movable system.
Start with the tunnel geometry and planned pour length. Then define the formwork, access platforms, travel arrangement and concrete placement interfaces around the way your site will work.
Images show reference configurations. Final dimensions, interfaces and supply scope are defined for each project.

Access. Movement.
- Curved steel formwork
- The outer form follows the required lining profile. Panel layout and pour length are part of the project configuration.
- Working platforms & stairs
- Multi-level platforms and access stairs are shown in the reference arrangements.
- Central passage & rail travel
- The reference photographs show side rails and a central passage. Clearances are reviewed against site requirements.
