Combining the system with standard components from other Doka
formwork systems
Using head units from the Dokaflex 1-
2-4 and Doka Xtra floor-slab systems
Using alternative screw-jack U-heads
* effective resistance of leg must always be ≤
22
kN, however
Using braces from the Load-bearing
tower d2 system
As an alternative to the diagonal crosses, it is also pos-
sible to use Diagonal braces d2 and Horizontal braces
d2 from the
Doka load-bearing tower d2
.

NOTICE
Deployment limitation:
▪
Cannot be used in conjunction with Staxo
40 anti-dropout lock.
For this reason:
- horizontal tower assembly is not
allowed
- tower is not allowed to be crane-lifted
- tower must not be used with e.g. brack-
ets or in any other applications where
tensile forces act upon the tower
▪
Do not mix the d2 braces with diagonal
crosses!
▪
Remember that these alternative parts have
different capacity ratings!
The permitted vertical loads must be diminished
by 10%!
The permitted horizontal loads must be diminished
by 15%!
