摘要

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