The working principle of the four-rope grab:

On the bridge crane, there are two sets of double-row rope drums. Each set of drums leads to two sets of steel wire ropes. One set of two steel wire ropes are tied to the inclined shells or (sling rope rings and bundles) at both ends of the grab balance frame. Rope bolt), used to support the wire rope. The other group of two is used for opening and closing wire ropes. They pass through the sheave pulley, the head pulley, and the lower beam pulley to form a pulley group, which plays the role of opening and closing the grab. When the work starts, support the wire rope to lift the grab bucket in the appropriate position, and then lower the opening and closing wire rope. At this time, the dead weight of the lower beam forces the bucket part to open centered on the major axis of the lower beam. When the head opens to the two ear plates, When the collision blocks collide, the bucket is opened to the maximum limit. When the grab is opened, the center distance between the upper beam pulley and the lower beam pulley is increased, and then the steel wire rope is supported to fall, and the opened grab bucket is dropped on the loose accumulation to be grabbed, and then the opening and closing wire rope is gathered, and the upper beam pulley and the lower beam pulley are connected. The center distance of the lower beam pulley returns to its original position, thus completing the process of grabbing materials. The closed bucket is filled with materials. Finally, the supporting wire rope and the opening and closing wire rope are lifted simultaneously. The entire grab is also lifted and moved to the required unloading ground by driving. The bucket is opened to unload the grabbed materials.
