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. |
