1.Grab bucket  has no retractable structure, and is usually driven by ropes or connecting rod force. According to operating characteristics, it can be divided into single rope grab and twin rope grab which is in the most common. 

2. Single-grab: support rope and open closed rope use the same one. Through special lock catch device, wire rope can take turns to play the role of supporting, opening and closing. The coiler mechanism of single coiler is simple, but production efficiency is low, so it is not often used when a factory has a large number of loading and unloading.

3. Double-rope grab: there are supporting rope and open closed rope which are respectively around the coiling block of supporting mechanism and opening/closing mechanism. It has such features as reliable work, simple operation, high production efficiency and wide application.It will be four-rope grab after adopting two groups of double ropes, and it has the same working course as double-rope grab.

4. According to bulk density of grabbed materials, grabs can be classified into light, medium-size and heavy ones. On the basis of the number of jaw plates, it can also be single-jaw grab and double-jaw grab which is used in the most common.Multi-jaw grab should be adopted for lump ore, scrap iron and steel scrap because it has such features as multi grabs and sharp cut, and it is easy to plug into material pile. This can get a better grab.
