Fagioli gantry lifting system
After detailed analysis and studies in order to create an
efficient lifting / lowering system able to execute the
No. 19 mobile gates’ installation operations, Fagioli
engineering department, after months of tests and 3d
simulations, ended up with the construction of a
reliable launching system with the following dimension:
HEIGHT 33,650m; LENGTH 47,019 m; WIDTH 18,500
m. The lifting capacity was 690 ton with a loading
capacity of 870 ton.

Pict. 3a - detail of the syncrolift beam Fagioli used Gantry lifting system, SPMTs and mobile
cranes to assemble the sections of the Launching
system. First, Fagioli assembled the Crosshead beams
then the towers were assembled (pict. 8). Fagioli used
SPMTs to mobilize the items and a 600 ton capacity
gantry lifting system to lift the structure (pict 9). The
crosshead beams, 47,019 m long, were provided on

In order to guarantee navigation in the
Port of Venice when the mobile barriers
are in operation, a main passage for
navigation, is being constructed at the
Malamocco inlet to allow the transit of
large ships

top with strand jacking system for the lowering / lifting
operations of the mobile gates (pict 10). No. 4 x 300
ton capacity strand jacks were fixed on top of the
crosshead beams. Then Fagioli completed the
assembly of the lateral movable towers, able to open
up for 180 degrees (pict 11). The towers were
connected at the top and at the bottom with no. 2
beams called bottom and top frames. A middle frame
is used to allow the rotation of the towers (see drawing
12). The drawing 17 shows a detail of the base frame
which was connected to the caisson, under the water,
once the gantry towers were opened. In order to
execute the installation of the gates it was built a
dedicated lifting system called «fishing beam». This
lifting device was connected to the strand jacking
system allowing the hooking of the gate for the
