The invention discloses a variable-amplitude crane for mounting a single-side arch rib of a steel tube arch bridge. The variable-amplitude crane for mounting the single-side arch rib of the steel tube arch bridge comprises a chassis, a suspension arm, a lifting assembly, a variable-amplitude assembly, a hoisting longitudinal moving assembly, a hoisting transverse moving assembly, a walking system and an anchoring assembly, the bottom of the suspension arm is hinged to a connecting lug plate on the front portion of the chassis through a pin shaft, the hoisting longitudinal moving assembly is installed on the upper portion of the suspension arm, the lifting assembly and the amplitude changing assembly are installed on the rear side of the connecting lug plate on the front portion of the chassis through bolts, the walking system is arranged on the lower portion of the chassis, and the anchoring assembly is installed on the rear portion of the chassis. The problems that an existing hoisting crane is heavy in structural weight and large in working space range or needs to pave rails on a full bridge are solved, the overall structure is simple and compact, the hoisting crane has the advantages of being convenient to disassemble and maintain, meanwhile, the maintenance cost is reduced, and the use efficiency is improved.
