摘要

A bridge maintenance vehicle with a hinge-connected type hanging bracket and capable of avoiding bridge-side obstacles comprises an unwheeling and a suspension arm. The unwheeling comprises a vehicle frame chassis (21). The suspension arm is a C-shaped hanging bracket (25). The vehicle frame chassis is connected to a lower end of a strut (23) in a hinged manner through a longitudinal shaft hinge (22) and a longitudinal shaft. A protruding end of a lower cross beam of the C-shaped hanging bracket (25) is provided with at least a fixing point for a lifting rope (26) or a lifting rope winding/unwinding device. A vehicle frame longitudinal beam (44) is fixed at an upper end of the strut (23). A hanging bracket longitudinal beam (42) is fixed at an upper end of a vertical rod of the C-shaped hanging bracket (25). The longitudinal beams are movably connected with each other into a whole through at least two cross beams (41).
