SMSS advantages

No need to use crane to

relocate the supporting

brackets from one column

to the next.

Easy to use on the water or

with very high columns.

-Lower the SMSS after the prestressing is installed

-Transfer the load reaction from the suspension gallows/rolling gallowes support to the launching

device

-Side shift both SMSS halves-Launch both SMSS halves to the next span

-Launch the suspension gallows/rolling support

-Close both SMSS halves

-Lift the SMSS to the concreting position

-While the rebar cage are installed the two supporting brackets pairs are transported to the next

columns, using the existing device located at the main girders and front nose

-Move the internal formwork to its position on the SMSS as soos as the rebar cage installation of the

bottom slab and webs is finished.

-Concreting

Typical SMSS cycle for a box cross section deck
