Heavy-duty supporting system SL-1
The fast, cost-saving solution for tunnel-building
Highly cost-efficient
thanks to its flexible modular system
Ensures efficient forming operations on every tunnel project, as
- all system components can be rented
- the system beams, walings and struts can be arranged in variable configurations, enabling optimum use to be made of each item of equipment
- it is 100% compatible with Large-area formwork Top 50
- it is exactly planned by Doka tunnel experts to ensure streamlined forming
Rapid working
right from the outset
Optimized all-in-one concept for swift construction progress, thanks to
- pre-assembly of the formwork and heavy-duty supporting-unit components, for short on-site erection times
- fewer form-tie points as Multi-purpose walings WU 16 and Form-ties 20 are used
- short repositioning times, achieved by the all-hydraulic formwork solutions
- easier working conditions, thanks to the wide spacing between the parallel girder frame units, and the heavy-duty telescopic screw-jack system
Stringent safety standards
thanks to the ingenious system logic
For reliable protection at your site, achieved by
- integrated working platforms and ladders
- detailed assembly and utilization planning
- safe travelling even on steep longitudinal and transverse gradients
- tried-and-tested, pre-dimensioned system design
- CE marking

The wide vault of one of the biggest tunnel caverns in Europe was formed using a tunnel formwork traveler that was divided along the middle. Separating the traveler into a left and right section made it very easy to assemble, and easy to reposition.
