positioned onto the SPMTs were turned 90° by the Fig. 11 – Sequence of
hydraulic system of the trailers. In the meantime operations
The Syncrolift Fagioli had already prepared a dedicated lifting
While at Lido Treporti and Chioggia harbors the system composed of:
caissons were built on dried yards which were then • skid tracks;
flooded with lagoon water at Malamocco harbor • 2 × 600 ton capacity gantry lifting system
there were not enough space to create such a provided with 2 × 300 ton capacity strand jacks
building yard. In order to bypass this problem it was positioned on top of it (figure 9).
decided by main contractor to install an elevator
called Syncrolift which was used to sank the After the rotation of the beams the two gantry lifting
caissons under the water level to allow the sea system were skidded onto the track in order to
transport till final destination (figure 6, figure 7). connect the beams to the lifting structure with link
The Syncrolift was composed of 57 m long beams plates and fixed anchor housings (figure 10). Fig. 12 - Lifting of the
(built by Omba) connected side-by-side to create a After the connection operations, the beams were barge at Cremona
wide area where the caissons were skidded and lifted by the gantry lifting system (while the barge river port
lowered into the water. Each beam weighed between
600 and 900 ton with width ranging from 6.5 m to
11.5 m and height of 5 m each.
Fagioli scope of work was the transport of the
beams at storage area close to the port, onto the
group-owned barge called Mak. Fagioli used special
trailers called SPMTs (Self propelled modular
transporters) to perform the hauling operations.
SPMTs are multi-axle modular trailers designed for
the transportation of heavy cargoes with an
outstanding transport capacity.
The load carrying capacity of a transporter platform
(or group of platforms) is directly proportional to the
number of axle line: the capacity of each axle line
used for this job was 30 ton. In order to complete
the load out of the beams onto the barge Fagioli
used 2 × 14 axle lines trailers (figure 8). Fagioli was
also responsible for the engineering and ballasting
operations during load out.
Once the barge arrived at Malamocco the beams
