Our company has nearly 50 years’ experience in the rental (both hot and cold) of operating machines and lattice cranes for port work. Ports in major Italian cities as well as in the Mediterranean basin have been built with cranes and equipment (mostly customized) made or serviced by our workshop.

The project to complete the Sicilian city’s dock was ambitious from the start.

The specificity of the work required the use of three Sennebogen lattice cranes (2200, 3300, and 5500) of 80, 110, and 150 tons capacity, respectively.

Our technical department working closely with the client provided for the design and subsequent fabrication in the workshop of a PRECOPAL sheet pile driving jig, a retaining structure for casting iron sheet piles, and finally 8 formwork units for making 6.3mc weakly reinforced concrete boulders.

The Sennebogen 2200 crane, the smallest of the three, operates to drive in iron sheet piles, which are then cast using the retaining structure built ad-hoc for this purpose.

The second crane, Sennebogen 3300, is used for driving PRECOPAL® type sheet piles, these are special fiberglass and polymer reinforced sheet piles. With this type of construction and because of the total absence of steel, a 100-year service life and prolonged corrosion resistance is guaranteed ^[1].

The last of the three the Sennebogen 5500 (150-ton) is used in two different phases: the first preparation phase, which is the flattening of the seabed in preparation for the second phase, which is the placement of the reinforced concrete boulders that will be used as the base for the subsequent port structures.
