A cable hoist special for a tool car comprises a machine frame and a cable plate, wherein the machine frame and the cable plate are of a steel structure. The cable plate is erected at the upper end of the machine frame through a bearing. At least three threaded holes are formed in the bottom of the machine frame. A bolt is arranged in each threaded hole. The head portion of each bolt perpendicularly extends to form a rotating handle. A guide device is further arranged on the bottom face of the machine frame. The guide device at least comprises two main guide bars, wherein the two main guide bars are perpendicularly welded into a whole. The cable hoist special for the tool car has the advantages that by means of the guide device and the bolts, the whole cable hoist is detachably arranged on the tool car, the functions of the cable hoist itself are ensured, the cable hoist is prevented from being repeatedly hoisted and detached in the construction process, and time and labor are saved; the whole cable hoist is of the steel structure, and therefore the requirements for bearing loads in the cable reeling and hoisting process are met, and the cable hoist is lighter in weight and more convenient to carry compared with an ordinary cable hoist of a wood structure or a solid steel structure.
