Bridge bearings play a critical role in transferring loads and accommodating movements between a bridge’s superstructure and substructure. When bearings deteriorate, timely replacement is essential to maintain structural safety and performance.

HiSCS recently completed the replacement of a damaged elastomeric bearing on a bridge pier supported by four bearings. A comprehensive jacking study was carried out in advance, defining the equipment layout, jack capacities, synchronization strategy, and all required safety measures.

The operation involved ten hydraulic jacks with a total lifting capacity of 1,000 tons. The bridge was carefully lifted under continuous monitoring of loads and displacements. Once the structure was stabilized, the deteriorated bearing was removed and the new bearing installed with precise positioning and alignment.

The works were completed safely and efficiently, restoring the bridge’s structural performance and ensuring long-term reliability. Precision engineering, rigorous safety planning, and expert execution remain at the core of every HiSCS lifting operation.
