摘要
The inventive sorting grille, comprising a frame reinforced with longitudinal and cross-linking of polymeric materials. It differs from the prior art in that the lattice consists of rigidly interconnected by the inner contour sections, each of which represents a different cast structure of its outer contour forms a polymer material based on synthetic rubber. The longitudinal and transverse internal circuit connection sections, on which the connecting them are formed of semicircular cross section. Compound internal circuits sections may implement polymeric strapping tape or cord, which does not increase the weight of the lattice, it is not subject to corrosion in seawater rack, durable and easy to assemble lattice. Section of the outer contour can be made oval or rectangular shape. Reinforcement of connections can be carried out with a steel or non-metallic rope. Longitudinal connection sections can be reinforced externally polymeric tubes, which further increases the strength of the lattice. 5 ZP f-ly, 4 Fig.
