1, product development and reference: According to the foreign product testing, with cutting-edge high-tech specific guidance of China's steel wire rope testing development trend, reference to the international work experience in the field of steel wire rope, product development of new steel wire rope production process.

2, commercial service testing report: China's quality testing units, sales requirements must give wire rope quality testing report. Enter the online mall system required qualification certificate testing report.

3, the prevention of safety production accidents: according to the use of steel wire rope to carry out a variety of data information to achieve collection, combined with analysis, according to the analysis, scientific determination of the use of steel wire rope. According to the damage situation of the steel wire rope analyzed, the corresponding maintenance plan is given for symptomatic treatment, to ensure the normal correlation between the friction pairs in the operation of the steel wire rope, and to complete the scientific use of rope.

The function of detection is to accurately feedback the quality of the wire rope, and then predict and analyze the service life of the wire rope, avoid safety risks, and ensure safety. And scientific specific guidance with rope, thereby increasing the use of wire rope life.

Second, what are the new items of steel wire rope testing?

The key items of new wire rope testing are twist, wire distance, rope warp, tensile strength, oil, continuous tensile test, twisting frequency, the whole rope tensile force, metal material cross-sectional area damage, partial damage and other new items, it is worth mentioning that the friction liner of the wire rope is also tested. New items of actual testing include relative density, strength, Lashen elastic die, tensile strength, compression modulus, stress, bending strength, reduced compressive strength, impact compressive strength, tensile strength, wear rate, friction resistance, wear amount, wear and other new items.

Subsequently, what are the inspection specifications and inspection methods of steel wire rope?

First, steel wire rope testing specifications are:

GB/T12753-2008 "Wire Rope for Conveyor belt"

GB/T12756-2018 "Hot-dip galvanized Steel Wire Rope for hydraulic hose"

GB/T9075-2008 Standard for Inspection and scrap of Rope for Sightseeing Ropeway

Finally, what are the criteria for scrap of wire rope detection?

1. The number of broken wires on the surface is 10% of the total number of wires on the rope or 2 broken wires occur within a twist distance. When the number of broken wires of the wire rope hoisting hot metal materials or dangerous goods reaches 5%, it is judged to be scrapped

2, the steel wire rope surface layer or internal structure has significant corrosion, it is judged to be scrapped.

3, the wire rope damage to the surface of 40% of the original wire diameter, it is judged to be scrapped.

4, the diameter of the wire rope is reduced by 7% or the core is expanded by 5%, then it is judged to be scrapped.

5. If the whole strand is broken or burned, it is judged to be scrapped.

6, part of the surface rope stretched in the shape of "cage" is more serious, it is judged to be scrapped.

7, the rope produced knots, extrusion, blind area, hard bending, plastic deformation, hemp core slip and other serious deformation is judged to be scrapped.

8, the position of the wire rope and the interface is cracked or moved deformation, more serious withdrawal, offset and other withdrawal conditions are judged to be scrapped.
