According to the packing density of the material to be grabbed, the grab bucket can be divided into light (such as grabbing grain), medium (such as grabbing sand) and heavy (such as grabbing iron ore). According to the number of jaw plate,it can be divided into double jaw plate grab and multi-jaw plate grab. The most commonly used is double jaw plate grab. The mechanical grab is through the opening and closing of the grab by the retracting of the wire rope, and generally cooperates with the professional grab crane.
