The invention discloses a hook device used for a crane, which comprises a hook (1) serving as a main body, rolls (4) and side hooks (3), wherein the rolls (4) are arranged on the two side surfaces of the hook (1) respectively and are in contact connection with the hook (1) and a steel wire rope connected with a mounting component simultaneously; the side hooks (3) are rotationally connected with the rolls (4); and spiral flange bodies are arranged on the rolls (4) on the two side surfaces of the hook (1), and set as the left spiral flange body and the right spiral flange body. When the steel wire rope hung on the hook (1) and connected with the mounting component moves, under the action of the spiral flange bodies on the rolls (4) in the two opposite directions, the stability of the movement of the steel wire rope connected with the mounting component and the stability of a position between the steel wire rope and the hook (1) are kept; no hook (1) is used directly, so that the stability performance of the hoisting mounting component is improved; and a docking surface of the mounting component is prevented from being damaged.
