The present invention relates to a shoe structure for a tongs crane. According to the shoe structure for a tongs crane with an improved structure of the present invention, the shoe structure detachably coupled to an end unit of a gripper arm of the tongs crane is improved so that first and second protrusion units spaced apart from each other are formed on upper and lower sides of the front surface of a shoe. Therefore, when the first protrusion unit is worn, upper and lower portions of the shoe are changed through an upper and lower switching operation of the shoe. Accordingly, a replacement cycle of the shoe can be extended, and a fixing structure of the shoe is improved, so that the shoe can be easily attached to and detached from the end unit of the gripper arm. The shoe structure for a tongs crane comprises: a pair of gripper arms (110, 120); the shoe (200); and a detachable means (300).
