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
