In April ALE was tasked with lifting the 500 tonne arched centre section of the Vicaria Bridge in Albacete, Spain. The operation was carried out using an auxiliary steel structure comprising beams supported over each transverse girder of the lateral spans. Four 200 tonne capacity HLS200 strand jacks were installed on the auxiliary sections.
The lifting began by progressively taking of the load until the central span of the arch was detached from its temporary supports. Following a topography test, the arch section was levelled and the four units began their simultaneous 40 m lift.
When the central span was close to its final elevation, another topography test was carried out. The span was then lifted into its final position and connected to the outer bridge decks. The job was completed in one day.
