The present invention relates to a hammer grab. A latching device is installed in the upper part of a tubular body with an inner space, and a slide box vertically moving by a power connection device is installed in the lower part of the latching device. The hammer grab is connected to a link device by the operation of the slide box so that a grab installed in the lower part of the body can be opened and closed. A pin connection unit to which a pin is connected is formed on both sides of an opening formed at the lower end on both sides of the body, respectively. The outer surface of the pin connection unit is located on the same line as the outer surface of the lower end of the body. A rod in the lowermost part of the link device is combined with the pin and integrally combined on the same line as the upper surface of the grab. Therefore, foreign substances are prevented from permeating between the grab and the rod in the lowermost part of the line device.

    본 발명은 해머 그랩에 관한 것으로, 내부공간이 형성된 관형의 몸체의 상부에는 걸림장치가 설치되고, 걸림장치의 하부에는 동력연결장치의 의해 상,하로 이동되는 슬라이드 박스가 구비되며, 상기 슬라이드 박스의 작동에 의해 링크장치와 연결되어 몸체 하부에 구비된 그랩을 개폐하는 해머 그랩에 있어서, 상기 몸체의 양측 하단부에 형성된 개구부에는 핀이 결합되는 핀 결합구가 양측에 각각 형성되되, 상기 핀결합구의 외측면은 상기 몸체 하단부 외측면과 동일 선상에 위치하며, 상기 링크장치의 최하단부의 로드는 상기 핀에 결합되되, 상기 그랩의 상부면과 동일선상으로 일체 결합되어 상기 그랩과 링크장치의 최하단부의 로드 사이에 이물질이 침투가 차단되는 것을 특징으로 한다.
