Grab bucket is a kind of lifting device for loading and unloading bulk materials by crane, which is widely used in ports, stations, mines and storage yards.
1. The strut is a closed welded structure, independent force transmission, stability, lateral bending ability is good;
2. The bushing of each hinge point adopts premium high manganese steel to prolong the service life of the grab;
3. Grab material weight and grab bucket weight ratio 1.5-1.9, grab ability is strong.
