What is the scrap standards of elevator ropes?

1. Fiber core steel wire ropes used for cast iron and steel wheel grooves can be visible to the num of roots of broken wires (SO4344: 2004 standard regulations)

2. In the “Elevator Supervision Inspection and Regular Inspection Rules and Mandatory Drive Elevator”, one of the following situations should be scrapped when hanging steel wire ropes and compensation wire ropes:

① Cage distortion, rope core extrusion, twisting, partially flattening, and bending.

②Broken wire dispersing appears in the entire steel wire rope, and the number of broken wires of the single stock in the twist distance is greater than 4; The wire rope with 6 shares) or more than 16 (for the steel wire rope with 8 shares);

③The diameter of the wear rope after the wear rope is less than 90%of the nominal diameter of the steel wire rope. If other types of suspension devices are used, the wear and deformation of the suspension device shall not exceed the scrap indicators set by the manufacturing unit.

Condition	Replace the wire rope or have it checked regularly by an inspector		Wire rope is directly scrapped
Condition	6x19FC	8x19FC	6x19FC	8x19FC
Number of broken wires in the outer strand	More than 12 strands per lay length	More than 15 strands per lay length	More than 24 strands per lay length	More than 30 strands per lay length
The number of broken wires is concentrated in one or two strands	More than 6 strands per lay length	More than 8 strands per lay length	More than 8 strands per lay length	More than 10 strands per lay length
Number of adjacent broken wires in one outer strand	4	4	More than 4	More than 4
Fracture of grain	One twist length	One twist length	More than one lay length	More than one lay length
The lay length of the wire rope is about 6 times the nominal diameter
