wireless remote control grab’s structure is reasonable ,opening and closing mechanism is novel.On the basis of the single-rope grab structure,using the wireless remote control grab automatic open in the air , the full realization of single-rope grab in the air unloading. Application easy to operate,reliable and stable operation.
Grab can be classified into shell-shape grab and orange petal shape grab.The former consists of two complete buckets, and the latter is made up of three or more than three jaws.
1.Mechanical grab: mechanical grab itself 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 situation.
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 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.
There is another shear type grab imitating scissors structure theory. Its grabbing force gradually increases with opening and closing of jaw plates; in the end the force reaches the max. The opening and area of its bucket mouth are bigger than ordinary grabs, which improve grabbing capacity and is easy to clean stock ground and cabin. But grabbing effect is poorer for bulk materials because its initial grabbing force is small.
