Italian company Fondamenta S.p.A. has deployed three Sennebogen cranes for a range of heavy lifts on the Verona-Padua high-speed rail project.
Contracted to build the Fibbio Bridge – a 2.3-kilometre section that will form an integral viaduct of the rail line – that will contribute to the Turin-Milan-Venice line on the Mediterranean corridor of the Trans-European Network, the Italian civil engineering specialist is using two Sennebogen 673E telescopic crawler cranes and one 1100G lattice boom crawler crane to conduct its heavy lifts.
Supplied by Italian distributor ESPI Engineering, the 673E features a maximum lifting capacity of 70 tonnes and a maximum hook height of 51m. The 1100G, on the other hand, possesses a maximum load capacity of 50 tonnes and also holds a maximum hook height of 51m. The three cranes will be lifting and erecting a total of 711 in-situ concrete piles within a year, with the cranes working alongside each other performing the same tasks. With the job site located in a precarious spot, Site Manager Nazario Sinigagliese said safety needs to be paramount – hence the decision to use the Sennebogen cranes.
“A big challenge on this construction site is, among other things, that the route is located between a gas pipeline in the ground and an above-ground power line that is still being laid in the ground during the railway construction work,” he said. “This means that all lifting, turning and pick and carry work has to be carried out particularly safely.”
The length and weight of the piles produced and lifted by the Sennebogen cranes are dependent on the type of subsoil, however on average weigh 6.5 tonnes and consist of four 12.5m long and 1.5m wide reinforcement cages. Assembled to form a long reinforcement cage by the 1100G and the 673E, the cages are then being inserted into the boreholes before being filled with concrete. According to assistant Site Manager Luigi Alberto D’Andrea, the Sennebogen cranes both provide unique advantages in this kind of work.
“Some crane operators prefer the 673 E telescopic crawler crane because it proves to be particularly flexible and versatile with regard to the varying activities on the construction site,” he said. “The 50-tonne crawler crane 1100 E, on the other hand, convinces with its functionality, especially when additional equipment is needed. When vibrating, for example, the lattice boom ensures even greater stability and excellently compensates for vibrations.”
Work on the Fibbio Bridge is expected be completed within a year.
Sennebogen’s products are distributed across Australia by NSW-based PACE Cranes.
