The invention discloses a hoisting tool for disassembling a railway scrapped open wagon chassis, and belongs to the technical field of disassembling and hoisting of railway scrapped carriages. Comprising a lifting frame, two travelling crane lifting lugs welded to the upper portion of the lifting frame, a lifting lug support hinged to the lifting frame, a self-locking clamping jaw connected with a bearing lifting chain on the lifting lug support, a lifting ring lifting chain connected with the travelling crane lifting lugs and a tension spring connected with the lifting frame and the lifting lug support. According to the hoisting tool, a double-beam four-head type vertical hoisting method is adopted, four self-locking clamping jaws of the tool are used for vertically hoisting a front hoisting handle, a rear hoisting handle, a left hoisting handle and a right hoisting handle of a disassembled part correspondingly, and balance and stability in the hoisting process are guaranteed; the rotatable lifting lug support is adopted, lifting of cutting pieces with different sizes within a certain range is met, frequent replacement of a lifting tool is avoided, and the lifting efficiency is improved; in addition, the invention designs a self-locking clamping jaw which is used for clamping and lifting a cylindrical lifting handle of the chassis cutting piece, so that the lifting is safer and more convenient.
