Double-compacted parallel laid wire rope for telescopic boom

Abstract

The invention discloses a double-compacted parallel laid wire rope for a telescopic boom. The double-compaction parallel laid wire rope comprises a center strand, nine inner strands and nine outer strands, the nine inner strands are symmetrically laid outside the center strand in a wrapping manner, the nine outer strands are symmetrically laid in grooves in the surfaces of the inner strands in a wrapping manner, the wire rope is a compacted rope, the strands in the rope are in surface contact, the outer strands are compacted strands, and steel wires in the outer strands are in surface contact. Due to the fact that the structures of the rope strands are in surface contact via being extruded by a die and the compacted wire rope is also in surface contact with a pulley contact surface, the double-compacted parallel laid wire rope for the telescopic boom has ultrahigh breaking force, high abrasion resistance, crumpling resistance and impact load resistance. Bearing capacity of the wire rope is 20% higher than that of wire ropes with same diameter and strength, abrasion resistance is improved by 25% approximately, service life of the wire rope is long, and operation cost of a telescopic boom crane is reduced correspondingly.

Description

Technical field [0001] The invention relates to a steel wire rope, in particular to a double compaction parallel twisted steel wire rope for a telescopic arm. Background technique [0002] With the development of telescopic boom cranes towards large-scale and miniaturization, the requirements for steel wire ropes for telescopic booms are also more and more bipolar, and the requirements for the breaking force, flexibility, and wear resistance of the wire ropes are becoming more and more stringent. At present, the existing steel wire ropes for telescopic booms can no longer meet the increasingly stringent performance requirements. Summary of the invention [0003] The purpose of the present invention is to provide a double compacted parallel twisted steel wire rope for a telescopic boom, which has the characteristics of high bearing capacity, good flexibility and good wear resistance, so as to solve the above-mentioned problems of the steel wire rope for a telescopic boom in the pri...
