The invention discloses a multi-parallel-trolley bearing mechanism for transporting large-tonnage prefabricated box girders. The multi-parallel-trolley bearing mechanism comprises a front girder transporting trolley (3), a rear girder transporting trolley (4), a front bearing beam (1) and a rear bearing beam (2), wherein the front bearing beam (1) is supported on the front girder transporting trolley (3), and the rear bearing beam (2) is supported on the rear girder transporting trolley (4). By utilizing an existing mature technology of large transporting equipment, various technical problems existing in transporting the large-tonnage and large-span prefabricated box girders under the multi-parallel-trolley condition are solved. By means of the multi-parallel-trolley bearing mechanism, a complete transporting system can transport the prefabricated box girders under special road conditions such as longitudinal slopes, transverse slops and especially small-curve roads, and internal stress applied on the bearing beams when the multiple trolleys do not run in a completely synchronous mode or the girder transporting trolley on a single side runs in a deflective mode can be released. The multi-parallel-trolley bearing mechanism is simple in principle, definite in stress and capable of being applied to other fields like large part transportation and solving similar technical problems.
