The invention belongs to the technical field of bridge construction, in particular to a hoisting device for bridge construction. The hoisting device for bridge construction comprises a hosting frame,an electric block and a controller. The bottom end of a steel wire rope of the electric block is connected with a fixing cross beam. A hinged seat is fixedly arranged at the top end of the fixing cross beam. The upper end of the hinged seat is hinged to the bottom end of the steel wire rope through a connection block. Hydraulic cavities are symmetrically formed in the fixing cross beam. First cross beam arms are arranged in the hydraulic cavities in a sliding manner. Second cross beam arms are arranged in the first cross beam arms in a sliding manner. Third cross beam arms are arranged in thesecond cross beam arms in a sliding manner. Liquid guide hole are formed between the hydraulic cavities and the first cross beam arms and the second cross beam arms. Liquid control valves are arrangedin the liquid guide holes. The upper end of the fixing cross beam is fixedly provided with a hydraulic oil tank. The hydraulic oil tank communicates with the oil guide pipe through a hydraulic oil pump. The end of the third cross beam arm is provided with multiple hooks. The hoisting device for bridge construction can conveniently hoist objects with instable gravity center, and improves the hoisting stability and safety of the objects at the same time.
