UP series paina with double jaw plate grab bucket is modelling novel, reasonable structure, grab materials weight and grab dead weight than only 1.5～1.92,full of degree is up to 95%～100% is minimal granularity of loose materials ideal catch to provide. And the traditional ordinary four rope compared to grab has the following characteristics:
1). The next bearing beam architecture is shortened, and the good strength and light weight;
2). Main hinge point of liner material for bearing steel.
