The invention provides a traveling crane lifting tool, and belonges to the field of mechanical manufacturing. When a traditional heavy load capacity traveling crane hoists and a workpiece is impacted, the traveling crane is strong impacted instantly, so the service life of the traveling crane is influenced. An upper cardboard and a lower cardboard are arranged in the inner cavity of the hoisting rack of the traveling crane, and a spring is arranged between the upper cardboard and the lower cardboard; and a hoisting rod is supported on the upper cardboard through a bearing arranged at the upper end of the hoisting rod, and the hoisting rod hoists a weight through a high temperature resistant chain in order to realize buffer connection between the traveling crane and the hoisted weight and the impact buffer effect of load on the traveling crane. The traveling crane hoisting tool has the advantages of shock resistance, automatic adjustment of the center of gravity, prolonged service life and the like.
