Introduction
Analysis of the core content of the standard
Terminology system
The standard has established a technical vocabulary system containing 72 core terms, which are mainly divided into:
- Wire assembly: defines 11 elements such as central wire and filling wire
- Strand structure: covers 9 typical structures such as parallel twist and composite twist
- Performance parameters: clarifies 23 indicators such as breaking tension and elastic modulus
Marking system
| Component type | Marking rule | Example |
|---|---|---|
| Single-layer multi-strand wire rope | Number of strands × structure - core type | 6×36WS-IWRC |
| Rotation-resistant wire rope | Total number of strands (number of layers) × structure - core type | 18×7-WSC |
| Sealed wire rope | Purpose code + structure | HLGR-for guidance |
Typical tag analysis: 8×K36WS-PWRC means 8-strand parallel lay compacted wire rope, Westrule structure, polymer filled parallel lay dense rope core.
Comparison of classification systems
| Classification dimensions | 2006 version | New content in the 2017 version |
|---|---|---|
| Structural classification | 6 major categories | 3 new special structures such as optical fiber cable and wire rope |
| Rotation characteristics | 2-level classification | Detailed into 3 torque levels (1-4r/1000d) |
| Diameter classification | Undefined | Newly added thin diameter (≤8mm), normal diameter, and thick diameter (＞60mm) |
Key points of technological evolution
- Quantification of anti-rotation performance: A new test method for the number of rotations is added, and three types of torque characteristics under 20% breaking tension are specified
- Expanded structure definition: The definition of combined parallel twist includes a triple combination of filling type + Warinton type + Siroo type
- Improved detection indicators: Five new performance parameters such as elastic modulus and bending fatigue are added
Implementation suggestions
- Standardized marking: Strictly follow the hierarchical order of "number of strands × structure-core type-surface state-twist direction"
- Selection reference: K-type compacted strand structure is preferred for lifting equipment, and 34(M)×7 type anti-rotation wire rope is recommended for mine hoisting
- Detection focus: For wire ropes with diameters greater than 60mm, special tests on torsion characteristics are required
