The present invention relates to a wireless remote control type automatic disjoint shackle using a triple elastic motor sensor. When a steel-frame structure or the like is lifted or lifted and moved to a desired location by using a tower crane in a general construction site, the present invention senses the moment when a hook of the tower crane is coupled with a shackle to lift the steel-frame structure, thereby securing the robustness and stability of the coupling state of the shackle. Further, even when a worker presses a shackle pin disjoint button by a malfunction of a remote controller, the present invention controls a shackle pin to be not disjointed from the shackle, thereby preventing safety accident due to the malfunction in advance. Further, the present invention can realize the coupling state between the shackle and the steel-frame structure more stably and can disjoint between the shackle and the steel-frame structure promptly and accurately after the completion of the work. Further, the present invention can prevent that the weight of the steel-frame structure is out of the allowable range. Further, the present invention allows a worker to display the joint and disjoint states of the hook of the tower crane at a hook connection part and the shackle pin at an opening part through the remote controller carried with the worker, thereby completely controlling safety accidents that may occur during the working. |
