Cut-and-cover method
Economical
- Less assembly work, because small number of shoring frames due to statically optimised load-bearing system
- Less work due to small number of operating points
Safe
- The optimised V-strut angles ensure high safety against overturning or slippage of the wall foundation
- Safe up/down access via integrated caged ladderway
- Large drive-through access openings for site traffic
- Clearly structured documentation from assembly drawings through to risk assessment
- CE mark is standard in Europe
Fast
- Hydraulic lifting appliance for easy lifting, lowering and precision-adjustment of the forming wagon - manual operation is also an option
- Optimised travelling structure for repositioning without adaptation
- Optional: Short set-up times, because components of formwork and load-bearing systems are pre-assembled

Safe to use
The innovative design ensures that the forming wagon remains securely on the rails, no issues with derailing even during lateral shifting.
Quick and easy repositioning
The hydraulic lifting appliance makes it easy to lift, lower and precision-adjust the forming wagon.

Cut-and-cover method
Diel tunnel | SlovakiaProject highlights
- The wide drive-through opening ensures smooth site traffic in all phases of the build
- Sustainable: After only minor adaptations, the forming wagon was used for another project
Cut-and-cover method
Stalvedro tunnel | SwitzerlandProject highlights
- Significant longitudinal gradients
- Easy conversion from round to rectangular cross-section
- Travelling on strip foundations
Cut-and-cover method
Schwamendingen tunnel | SwitzerlandProject highlights
- Deployment of the forming wagon in both traffic directions
- Deployment while traffic passes in the opposite direction
- Movable stop-end formwork for lane edges
