Abstract (en)
[origin: US4692981A] The process is used for replacing bridge bearings between pier and superstructure, by the superstructure being lifted relative to the pier (1) by lifting cylinders (8) and the bridge bearing, made thus accessible, being totally or partially replaced. Parts of the old bridge bearing are removed from over the pier contact surface (2) and thus mounting surfaces (12) for lifting cylinders (8) are created under longitudinal web (5) and/or crossbeam (6) of the superstructure on the pier contact surface. Removal of the old bearing parts takes place in such a way, and mounting of lifting cylinders (8) on mounting surfaces (12) is performed so that, after lifting of the superstructure not only are the remaining parts of the old bearing, which are to be replaced, removed by the corresponding new bearing parts installed between lifting cylinders (8).
