When
only two tie levels are remaining
, it is important to
proceed with extreme care
to
make sure that the stability of the motorized unit is not compromised during the operation.
WARNING
Before the start of dismantling operations
of a setup installed following installation
method “D”, it is
mandatory
to uninstall any equipment, accessory or bridge, leaving
only one
5' (1,5 m) bridge attached at the cantilever end of each motorized unit,
leaving the bearing bridge structure in place (fi g. 1.53, p. 41).

only
one 5' (1,5 m) cantilever attached at each end of each
motorized unit
.
Before removing the last two tie levels
