Mabey Hire heavy duty jacking

Controlled bridge jacking and lifting

Bridge jacking lifts a bridge in a controlled, synchronised operation so that bearing replacement, strengthening or repairs can be carried out safely underneath. The structure is raised in small increments, held, then set down exactly where it should be.

Every scheme is designed by our temporary works engineers. Lifts use hydraulic jacking equipment from our own hire fleet, with loads and movement monitored throughout. As part of our bridging and site access solutions, we lift everything from footbridges to highway and rail structures.

Why choose Mabey Hire for bridge jacking?

Engineered lifts

Every jacking scheme can be designed by our temporary works engineers, from jacking points and load paths to the lift sequence itself, so the structure is protected at every stage.

Synchronised and monitored

Jacks work together in small, controlled increments. Loads and movement are monitored continuously, keeping the deck level and the lift within millimetre tolerances throughout.

One complete package

Lifting, holding, and monitoring the structure, all from one hire fleet, with our engineers on site and structural monitoring available for the full duration of the works.

When do bridges need jacking?

Most bridge jacking is planned: lifting the deck to replace seized bearings, install strengthening works, or carry out repairs and re-levelling.

Some work isn’t planned, and after a bridge strike, jacking is often a key part of getting the route reopened quickly and safely.

We support bearing replacement, strengthening and emergency works across highways and rail.

Controlled and synchronised bridge jacking

Bridges are lifted in small, synchronised increments, with hydraulic jacks working together so the structure stays level throughout.

Low height jacks work within the limited headroom beneath a deck, and heavy duty propping holds the structure safely while works are carried out. All of this can be hired from Mabey Hire.

This can often be done with the bridge remaining open to traffic, and structural monitoring watches the structure for the duration.

FAQs

Can a bridge stay open during jacking?

Often, yes. Because the structure is lifted in small, synchronised increments, many bridges can remain open under traffic management during the works. Whether that’s possible depends on the structure and the scope, which our engineers assess at design stage.

How long does bridge jacking take?

The lift itself is usually fairly quick. However, the overall programme is driven by the works underneath. Times can vary depending on th bearing replacement or strengthening, and by access arrangements like road closures or rail possessions.

Who designs the jacking system?

Our in-house temporary works engineers design every scheme, covering jacking points, load paths and the lift sequence, in line with BS 5975 temporary works procedures.
