Bridge Lifting And Replacement of Bearing

Damaged Bearing

Bearing is very important structural element of bridge. Its malfunction result into very serious damage to superstructure and substructure. So damage/malfunctioning bearings needs to be replaced. Hence to cater very important need of bridge we carry out inspection of bearings to identify damage/malfunctioning bearings. Then we assess the structure for preparing possible lifting arrangement. We have replaced bearings of 7 spans of existing bridges where superstructure was badly damaged in very adverse conditions. Now a days construction period has come down drastically so speedy construction new techniques has to be adopted.

Now a days construction period has come down drastically so speedy construction new techniques has to be adopted. So in some case bearings are placed after casting superstructure ( due various reasons e.g. non availability of bearings at time construction , change in design , delay in the project, etc.) . So Installation of bearings has to carry out by lifting the superstructure . We have carried out installation of bearings of 55 spans for ( Ghoshpukur-Salsalabari Road Project ) on fast track basis (i.e. in 3.5 months)

Lifting Arrangement

Powerpack Lifting

We have modern & variety of hydraulic jacks for all kind of lifting. We have more than 70 hydraulic jacks which are operated by Power Pack.
