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.
3). Prolong the service life of the 4～5 times, and the blade plate adopts the wear-resisting materials which enhance the impact and friction level, the pulley multi-layer seal process, dust proof, waterproof can underwater operations, the blade plate together gab clearance small, can achieve 0.3 mm～1 mm can keep clean, the hole structure the work place have strong shape not easily dislocation, this type of grab can design for double rope.
