Whether occurring during a design-build project or as a primary step to perform repair or maintenance activities, lifting or handling heavy structures remains challenging. It demands control over the stresses induced in the structure throughout the whole process. Conducting such operations requires engineering expertise, reliable equipment, careful operating, and precise placement. Relying on skilled and experienced teams and thorough risk management to ensure worker safety, structure preservation, and worksite surroundings protection is essential, especially when these operations are carried out in dense urban areas.
From cable-stayed bridge rotation to stadium roof lifting, from underpass bridge sliding to hauling-up of water tower tanks, through to jacking-up operations, we will offer you the most appropriate solutions, especially when other conventional installation methods are impractical, risky or too costly.

Heavy handling includes:

  • heavy lifting, which consists in moving a structure or a load vertically,
  • sliding, which involves the horizontal shift of a structure or a load,
  • rotation sometimes, when the operation also entails a change in orientation of the structure.

Complex projects may often necessitate to combine several operations, especially when adjusting the structure in its final position. This is where our expertise, specialist teams and capability to drive and manage the project in all aspects will make the difference.

Discover our case studies

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.

  • 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.

Sliding and rotation operations are used to install structures that must overpass or underpass obstacles like railroad, highway, or valley crossings.

These operations can be performed at ground level on a short distance, and at heights, when heavy structures are shifted to their final position or when heavy loads are removed from their current position. These methods apply to new build projects, structure dismantling or when replacing part of an existing structure.

Launching

Launching is a longitudinal sliding method that allows to cross gaps. It is the preferred construction method for bridges crossing valleys or rivers. The bridge deck is prefabricated behind one of the abutments. Installation consists in sliding deck sections over sliding bearings onto the bridge piers, while a launching nose prevents bending moments, as part of the installation is done above the void. Launch is operated with high-capacity hydraulic jacks.
  • Cost-effective solution
  • Minimal traffic disruption of underpass lanes
  • No impact of bridge height

Autoripage® structure sliding technique

This patented method developed by Freyssinet enables the installation of a structure entirely prefabricated on a nearby base -usually next to the road or railway track - and sliding it to its final position onto bentonite grout, after completely clearing the ground. After sliding completion, backfilling is carried out to re-open the route to traffic. The method is particularly appropriate for railroad crossing.
  • Fast execution
  • Short track closure
  • New structure built near final position

Autofonçage® structure sliding technique

Also developed by Freyssinet, Autofonçage® is a patented structure sliding method which enables the creation of a short underpass structure under traffic lanes in operation. It consists in prefabricating sections of the structure (concrete frames), then sliding them after partly clearing the ground and driving the structure forward into the infill as the excavation work progresses. No backfilling is required, as the volume of earth excavated equals that of the structure.
  • Fast execution
  • Reduced traffic disruption
  • Structure sections built near final position

Air Pad Sliding

Air Pad Sliding (APS) is an alternative to Autoripage® using APS bearings, a patented device: after clearing the ground, heavy structures are horizontally moved to their final position along skidways onto APS modules. Skidways are equipped with side guides and adapted to the bearing capacity of the soil. Once the sliding operation is completed, backfilling takes place to re-open the route to traffic.
  • Friction coefficient <1 %
  • Skidding speed up to 150m/h
  • Multidirectional lifting and sliding

Lateral sliding

When a bridge deck needs to be replaced, a practical solution consists in building the new one next to the old one. Therefore, the new deck is built on a temporary support. Once completed and during a short possession, the old deck is de-slided and the new one slided into final position. This method allows replacement of long decks at heights, when cranage is impossible.
  • Friction coefficient < 5%
  • Sliding speed up to 15m/h
  • Long and heavy slide

Rotation

When it is impossible or costly to build overpass bridges above the obstacle to overcome (e.g. motorway in operation), rotation operations are interesting solutions to install bridges in their final position. In this case, the structure is built perpendicular to its final position, along the track. Rotation is operated from a central pivot or from an end pivot (located at one of the bridge deck’s ends).
  • Friction coefficient < 5%
  • Minimum traffic disruption
