The present invention relates to an opening device of a manhole cover and, more specifically, to an opening device for a manhole cover, which can be conveniently moved and easily opened. The opening device for the manhole cover comprises a body (200) and a handle (110) extending from the body (200). The body (200) includes: an open rod (220) formed at the bottom with a T-shaped hook (226) caught by rotating and being inserted into the manhole cover (10); a first hydraulic ram (230) which lifts the open rod (220) to bring the manhole cover (10) and the T-shaped hook (226) closer; and a second hydraulic ram (240) which raises the body (200) by extending in the opposite direction to the first hydraulic ram (230).

    본 발명은 집수정 덮개의 개방장치에 관한 것으로, 보다 상세하게는 이동이 편하고 손쉽게 개방할 수 있는 집수정 덮개의 개방장치에 관한 것이다. 이를 위해, 본체(200) 및 본체(200)로부터 연장되는 핸들(110)로 구성되고, 본체(200)는, 집수정 덮개(10) 사이로 삽입되어 회전함으로써 걸리는 T형후크(226)가 하단에 형성된 개방로드(220); 개방로드(220)를 상승시켜 집수정 덮개(10)와 T형후크(226)를 밀착시키는 제 1 유압램(230); 및 제 1 유압램(230)과 반대방향으로 신장됨으로써 본체(200)를 상승시키는 제 2 유압램(240);을 포함하는 것을 특징으로 하는 집수정 덮개의 개방장치가 제공된다.
