The invention aims to provide the movable counterweight system for the suspension lifting platform, which is compact in structure, stable in operation and capable of effectively prolonging the service life. The bridge comprises a bridge body, a pulley assembly, a movable counterweight assembly and a lifting platform, the pulley assembly is arranged on the bridge body, the movable counterweight assembly and the lifting platform are arranged on the two opposite sides of the bridge body respectively, and the lifting platform is arranged on the bridge body in a sliding fit mode. The movable balance weight assembly comprises a first balance weight block and a second balance weight block, the first balance weight block, the second balance weight block and the lifting platform are all connected with the pulley assembly, and the lifting platform can do transverse reciprocating motion along the bridge body. And the first balancing weight and the second balancing weight are always opposite to the movement direction of the lifting platform. The invention is applied to the technical field of airport maintenance platform structures.
