Scope

Scope: This document specifies the terms and definitions, classification, technical requirements, rope inspection, rope testing, inspection rules, acceptance, packaging, storage and transportation, and marking and quality certificates for fiber-core steel ropes with a structure of 8×19 S/19 W and a diameter of 8 mm to 16 mm. This document is applicable to fiber-core steel ropes used for traction in medium-speed elevators with an operating speed of 1.75 m/s to 2.5 m/s, as well as traction ropes used in elevator systems without machine rooms. This document is not applicable to traction ropes used in elevators with an operating speed below 1.75 m/s, traction ropes with semi-steel or full-steel cores used in elevators with an operating speed of 1.75 m/s to 2.5 m/s, or speed limiter ropes. Main technical contents: The document sets corresponding requirements for 13 indicators, including rope diameter, breaking force, performance of stranding wires, straightness, fatigue life, elastic elongation, structural elongation, and elastic modulus. Among these, the technical indicators for diameter uniformity, non-roundness, performance of stranding wires, and structural elongation exceed the industry standard GB/T 8903-2018 "Steel Ropes for Elevators". The technical indicators for breaking force and rope diameter tolerance are identical to the industry standard GB/T 8903-2018 "Steel Ropes for Elevators".
