Bridge Lifting

A large red hydraulic jack with a cylindrical body is positioned horizontally on a concrete surface. Two steel beams rest atop a base nearby. Cables and a metal structure are visible in the background, suggesting a construction setting.

Our bridge lifting system, which employs hydraulic jacks, allows for the execution of maintenance work and for a quick and safe replacement of the spans’ support systems. The bridge lifting system is also used for the launch of new spans, ensuring millimeter precision. Having different types of jacks, we can provide the best solution for any type of bridge and construction site situation.

 

Special Projects

A view of a multi-story building under construction, surrounded by trees. A crane is positioned beside the structure, lifting materials. Construction equipment and supplies are scattered in the vicinity.

Our hydraulic jacking system can be used not only to jack concrete boxes, but also to move and reposition buildings and houses. Our technicians examine all phases of the project, from designing the system to moving the building, to prevent and avoid any damages to the structure.

 

Loading tests of the underpasses

Two workers in bright orange safety gear are operating machinery under a snowy bridge. One operates a lift, while the other adjusts equipment. The bridge walls and wintry ground are partially seen.

Petrucco has developed a load test system for underpasses that allows for verification without having to place any weight on the extrados of the concrete box (upper slab). The load test must be completed before pushing the underpass. This system, which is always applicable, makes the load test faster, cheaper and less risky than traditional methods.
