High-extensibility fiber core steel rope
The utility model relates to a stainless steel cable field especially relates to a fiber core steel cable of high extensibility.
The steel wire rope is a spiral steel wire bundle formed by twisting steel wires with mechanical property and geometric dimension meeting requirements together according to a certain rule, and consists of the steel wires, a rope core and lubricating grease. The steel wire rope is a spiral rope which is formed by twisting a plurality of layers of steel wires into strands, and then twisting a certain number of strands by taking a rope core as a center. In a material handling machine for lifting, pulling, tensioning and carrying. The steel wire rope has high strength, light dead weight, stable work, difficult sudden whole breakage and reliable work.
The steel wire rope needs to bear the alternating load in the using process, and the using performance of the steel wire rope is mainly determined by the mechanical property of the steel wire, the surface state of the steel wire and the structure of the steel wire rope. The rope core mainly plays a supporting role for the steel wire rope so as to achieve a stable cross section structure. The rope core includes a steel core and a fiber core, the fiber core includes a natural fiber core such as sisal, jute, cotton and the like, and a synthetic fiber core includes polyethylene and polypropylene filaments and the like.
