This standard applies to traction steel wire ropes and balance steel wire ropes for all types of elevators and escalators. Core revisions include: first, upgraded material performance, adopting new materials such as high-carbon steel, rare earth alloy, nano-coating, steel wire tensile strength ≥2000MPa (increased by 25%), toughness increased by 40%, low temperature resistance -40℃, high temperature resistance 150℃; second, optimized structure design, promoting 8×19W, 8×25Fi, 6×36WS high wear-resistant, low elongation structure, steel wire rope elongation rate ≤0.2% (no slipping during operation), non-rotating, anti-extrusion, fatigue-resistant, adapting to high-speed and ultra-high-speed elevators; third, improved fatigue life, bending fatigue life ≥1 million cycles (doubled), design life ≥20 years, equipped with online wear monitoring, automatic tension balance, regular flaw detection system, early warning of broken wire, wear and corrosion hidden dangers; fourth, strengthened anti-corrosion and wear resistance, adopting zinc-aluminum-rare earth composite coating, polyamide sheath, self-lubricating coating, anti-corrosion life ≥15 years, wear resistance increased by 60%, adapting to humid, corrosive and high-dust environments; fifth, tightened safety factor, elevator steel wire rope safety factor ≥12 (old standard 10), balance rope safety factor ≥10, stricter scrapping standards for broken wire, wear, diameter reduction, strictly prohibiting overdue use; sixth, testing and certification specification, formulating full mandatory standards for tensile test, fatigue test, wear test, corrosion test, flaw detection test, must pass special equipment type test, third-party testing qualified before use. After implementation, this standard will completely solve elevator steel wire rope broken wire and fracture safety hazards, elevator operation safety factor increased by 30%, providing a Chinese model for global elevator steel wire rope safety standards.
