Four-Rope Pie Grab
Up serial Paina double jaw grab is featured of novel shaping, logical structure, the rate of 1.5-1.92 between gabbed materials and grab dead load, filling degree of 95-100%, which is an ideal grab for loose granule materials.

Application scenario
Compared with traditional four cable grab, the product owns characteristics as follows: the through beam is designed with abbreviated structure, fine strength and slight dead load, the lining material of main swivel is made of bearing steel, whose service life is pronged 4-5 times.
The cutting edge sheet is weld by overlaying techniques to enforce impulse force and abrasion strength. The chain wheel is sealed by multi lay techniques to prevent dust and water in underwater operation. The commissural clearance between cutting edge sheets can reach 0.3-1mm to keep working place clean. The structure is hard to deform or stagger, the kind of grab can be designed with two cables.
