The invention discloses a precise hoisting machine tool for a traveling crane. The precise hoisting machine tool comprises a cylinder body of the precise hoisting machine tool of the traveling crane, an upper end cover, a piston rod, a piston, a lower end cover, a hydraulic control unidirectional valve, a unidirectional speed regulating valve, an electromagnetic reversing valve, an overflow valve, an oil pump and an oil tank. According to the invention, based on a common traveling crane, the precise hoisting machine tool is additionally installed for the traveling crane; the flowing state of a liquid in the precise hoisting machine of the traveling crane is controlled by controlling power on and off of the electromagnetic reversing valve so as to further control the operation state of the precise hoisting machine tool, so that the precise hoisting of the traveling crane in important occasions is realized, and important hoisted workpieces are protected. The precise hoisting machine tool for the traveling crane, which is provided by the invention, is simple in structure, is reliable in operation, can complete the precise hoisting operation of the traveling crane, fully protect the important hoisted workpieces, and has a wide application prospect.
