At JASO, we design and supply double girder gantry cranes for concrete precast factories, as well as for infrastructure and tunnel construction projects.

In the area of concrete precast factories, we supply cranes with standard hoists in single and double girder gantry versions that work within the process of concrete setting and parts production. In addition, we install gantries with independent generators that work in tandem, to empty sections of bridges and roads up to 20 metres long and 100 tons in weight, parts that will later be used in projects and highways around the world.

As for the tunnel construction industry, we can highlight our extensive experience in attack gantries for the delivery of keystones to the tunnel boring machine and storage gantries, which are responsible for collecting the materials that come from the precast factories and then installing them inside the tunnel. With work groups up to M8, long hook paths and capacities up to 120 tons, these cranes work 24 hours a day, 7 days a week with complete reliability, so that the construction works never stop.

As of today, JASO has contributed important construction works in Spain such as the AVE tunnel, the Barcelona metro system and the tunnels and roads of Madrid´s M30. At international level, one of our last projects carried out in Saudi Arabia was for the construction of the Riyadh metro system.
