- Move the lifted modules to support them on the
jack walers and fasten with bolts M24. Check the
levelling of the structure.
- Likewise proceed with as many structures as
indicated in the assembly drawings. Usually two
structures are lifted together. The bracing with
horizontal braces and diagonals between the
structures is made after having placed them in their
final position.
- In the case of combinations between MK Shoring
Towers and MK Structure (Cut-and-cover tunnel form
carrier), the lifting is carried out in several steps. To
place the structure on towers, use walkway
platforms.
- Lift the structure and connect it to the towers with
bolts M24. Use a pointed pin to help inserting the
bolts into the holes.
- Remove the statutory auxiliary lifting means, and
platforms and auxiliary ladders (if applies).
- Proceed with covering the parts of the structure
with plywood which are indicated in the assembly
drawings.
