Heavy lifting can be performed at different heights, depending on the structure or load to be lifted (dimensions, shape, weight…), worksite configuration, and purpose of the operation. To handle the structure or load involved, our teams operate the strand lifting or precision jacking methods.

Strand lifting

Heavy lifting using the strand jacking technology can be performed to quickly raise or lower almost any load, regardless of the height. This method is an appropriate solution when lifts have large dimensions, when loads require several lifting points, must be moved horizontally at heights, or require precise handling or placement in their final position.

Applications: bridges, buildings, nuclear plants, power plants, stadiums.
  • Cost-effective method
  • Fast process completion
  • Improved safety conditions

Precision jacking

This technique ensures safe and accurate lifting/lowering of rigid structures necessarily requiring multiple lifting points, due to uninterrupted control of the load movements in operations such as structure raising or decentering and bearing replacement. Computer-aided jacking operations can be performed in confined areas and support up to several thousand tons by several meters. Our computer-aided LAO® jacking system designed in-house has 48 separate hydraulic ways which already allowed us to lift structures up to 100,000 tons with a 0.3 mm accuracy.

Applications: bridges, buildings, nuclear plants, power plants.
  • Real-time control
  • Constant analysis of
    lifting parameters
  • Monitoring of stroke variations
    between lifting jacks
