PURPOSE: A double line connecting device for a crane is provided to prevent degradation of work efficiency due to increased work time and inconvenience caused by re-coupling or separating a wire connecting ring according as a hook is connected to a double line wire without separation of the wire connecting ring. CONSTITUTION: A double wire connecting device for a crane(100) comprises a base panel(110), a cover panel(130), a pulley(120), and a hook connection ring coupling part(150). The cover panel is connected to the base panel while being separated from the base panel. The pulley is rotatably connected between the base panel and the cover panel. The hook connection ring coupling part is formed in at least one of the base panel and the cover panel. In a state where a wire connection ring is connected to a wire, the wire connection ring is penetrated through between the base panel and the cover panel so that the wire can be hung on the pulley. The wire connection ring is connected to an arm and the wire connected to the arm by a double line. A hook connection ring is coupled to the hook connection ring coupling part so that a hook can be connected to the wire connected to the arm by the double line. |
