The present invention relates to a hydraulic grab bucket, which is structurally improved so that a stopper for limiting the downward swirl angle of a claw is formed integrally with a main plate, thereby improving workability and precision compared to a conventional method of joining by welding, etc. In particular, since a compartment in which a hydraulic cylinder is installed is configured to be opened and closed by a cover module, the hydraulic cylinder is safely protected from external collision objects in normal times, and when the hydraulic cylinder is repaired, the cover module can be opened upward to simply replace the hydraulic cylinder. In addition, a hinge hole area where a load is concentrated during the clamping/unclamping operation of the claw is reinforced and supported by the cover module, thereby improving durability. The main configuration comprises a main body (10), a main plate (20), a claw (30), a hydraulic cylinder (40), and a stopper (50).

    본 발명은 유압식 그랩버킷에 관련되며, 이는 클로우의 하향 선회각도를 제한하는 스토퍼가 메인플레이트에 일체로 형성되도록 구조 개선되어 용접 등으로 접합하는 기존 방식 대비 작업성 및 정밀도가 향상되되고, 특히, 유압실린더가 설치되는 격실이 커버모듈에 의해 개폐되도록 구성되므로, 평상시 외부충돌물로부터 유압실린더를 안전하게 보호하고, 유압실린더를 수리시 커버모듈을 상향 개방작동하여 유압실린더를 간단하게 교체할 수 있으며, 또 클로우의 클램핑/언클램핑 작동시 하중이 집중되는 힌지홀 영역이 커버모듈에 의해 보강 지지되어 내구성 향상을 도모할 수 있도록 메인바디(10), 메인플레이트(20), 클로우(30), 유압실린더(40), 스토퍼(50)를 포함하여 주요 구성으로 한다.
