According to an embodiment of the present invention, an auxiliary hook device for collecting a weight includes a hook unit and a bar unit. The hook unit includes: a ring-shape hook member in which an open unit is placed at one side, a pin fixing hole passes through closely to the opening unit, and a bar latch member protrudes from one side of the outer circumferential surface; a hook opening/closing member of which one end is combined with the pin fixing hole to be moveable and the other end is latched to one side of the hook member; an opening/closing member fixing pin which is inserted into the pin fixing hole; and an opening/closing member returning spring which surrounds the outer circumferential surface of the opening/closing member fixing pin and applies elastic force for the hook opening/closing member to elastically return. The bar unit includes: a hook latch member which is combined with the bar latch member to be slidable and detachable; and a bar member which is combined with the hook latch member. Therefore, according to the auxiliary hook device for collecting a weight and an operation method thereof given in the embodiment of the present invention, as the bar unit and the hook unit are slide-combined and the opening unit of the C-shape hook member is closed by the hook opening/closing member which is elastically supported, a rope fixing ring prepared at one side of a weight is latched to the inner circumferential surface of the C-shape hook member, so industrial accidents during the work can be prevented and the auxiliary hook device for collecting a weight which has been already used by being latched to the inner circumferential surface of the hook member can be collected and reused. 본 발명의 일실시예에 따른 중량물회수 보조후크 작업장치는, 일측에 개구부가 구비되며 상기 개구부에 인접되게 핀고정공이 관통ㆍ형성되며 외주면 일측에 장대걸림부재가 돌출ㆍ형성되는 고리형상의 후크부재, 일단부가 상기 핀고정공에 회동가능하게 결합되며 타단부가 상기 후크부재의 일측에 걸리는 후크개폐부재, 상기 핀고정공에 삽입ㆍ배치되는 개폐부재고정핀, 그리고 상기 개폐부재고정핀의 외주면을 감싸며 상기 후크개폐부재가 탄성ㆍ복귀되도록 탄성력을 인가시키는 개폐부재복귀스프링을 가지는 후크부; 및 일측에는 상기 장대걸림부재에 슬라이딩되게 탈착ㆍ결합되는 후크걸림부재, 상기 후크걸림부재에 결합되는 장대부재를 가지는 장대부;를 포함하는 것을 특징으로 한다. 따라서, 상기와 같이 구성되는 본 발명의 일실시예에 따른 중량물회수 보조후크 작업장치 및 그 운용방법에 따르면, 슬라이딩 결합되는 장대부와 후크부로 구성되어, 상기 후크부는 일측에 개구부를 가지는 C자형상의 후크부재의 상기 개구부가 탄성지지되는 후크개폐부재에 의하여 닫힘에 따라, C자형상의 상기 후크부재의 내주면에 중량물 일측에 구비되는 로프고정고리가 걸리도록 구성함으로써, 작업에 따른 산업재해를 사전에 방지할 수 있으며, 후크부재의 내주면에 걸려서 한번 사용된 중량물회수 보조후크 작업장치를 다시 회수하여 재사용할 수 있는 효과가 있다.
