Disclosed is a lifting device capable of adjusting the center of gravity. The lifting device includes: a main body unit (110) having an inner space (111) and a sliding groove (112) formed on the upper surface and extended in a longitudinal direction (L); a transfer block (120) mounted in the inner space (111) to be able to slide in the longitudinal direction (L), wherein a connection ring (121) connected to a hook (10) is mounted on the upper part thereof to be exposed to the sliding groove (112); a first sling (140) and a second sling (150) extended at a predetermined length, wherein both ends are connected to both sides of one side and both sides of the other side, respectively; and a first pulley (160) and a second pulley (170) individually mounted on both sides of the main body unit (110) in the longitudinal direction (L) in order to rotate and controlling the length on both sides of the slings (140, 150) relatively according to the rotation, wherein a middle part of the slings (140, 150) is hung on and supported by sling grooves (161, 171).

    본 발명에 따르면, 내부공간(111)이 형성되며 상부면에는 길이방향(L)으로 연장된 슬라이딩홈(112)이 형성된 본체부(110); 상기 내부공간(111) 내에서 길이방향(L)으로 슬라이딩 이동이 가능하게 장착되며, 상부에는 후크(10)에 연결되는 연결링(121)이 상기 슬라이딩홈(112)으로 노출되게 장착되는 이송블럭(120); 일정길이로 연장형성되어 구조물(20)의 일측부 양측과 타측부 양측에 양단이 각각 체결되는 제1슬링(140) 및 제2슬링(150); 및 상기 본체부(110)의 길이방향(L) 양측에 각각 회전가능하게 장착되어 각 슬링(140,150)의 중앙부가 슬링홈(161,171)에 걸쳐져 지지되며, 회전함에 따라 각 슬링(140,150)의 양측 길이를 상대적으로 조절하는 제1풀리(160) 및 제2풀리(170);를 포함하는 무게중심 조절형 리프팅 장치를 개시한다.
