The term "detailed" fits best when referring to steel wire ropes, which come in various types and have complex specifications. Each number and letter carries a unique meaning, so understanding these markings is crucial. A wire rope manufacturer is here to explain how different types of wire ropes are labeled.
1. Full Marking for Single-Lay Steel Wire Ropes and Enclosed Steel Wire Ropes:
Start from the outer part of the rope toward the center, layer by layer, noting the number of wires, including the central wire, separated by a "+". For instance, a single-strand wire rope: 12+6+1.
For non-circular cross-section wires, add the relevant symbol next to the wire count. For example, an enclosed wire rope: 23Z+9H+12+6+1.
2. Full Name Marking for Double-Lay Wire Ropes:
Mark from the outer layer to the center, indicating the total number of strands per layer, separated by "+". Then, detail the structure of each strand, starting from the outermost layer inward, listing the number of wires per layer, including the central wire or fiber core. For natural fiber core multi-strand ropes: 12(6+1)+6(6+1)+NF.
For metal strand core ropes, separate the strand structure from the core using a "+". Example: metal strand core wire rope: 6(6+1)+IWS(6+1).
For metal rope core ropes, separate the rope core structure from the strand structure using "+", with the strand structure noted in brackets. Example: metal rope core Silu rope: 6(10+10+1)+IWR[6(6+1)+IWS(6+1)].
For filler ropes, denote the filler wire with "F" and separate it from the corresponding layer with "+". Example: metal rope core filler rope: 6(12+6F+6+1)+IWRC6(6+1)+IWS(6+1)).
For Walinzon ropes, differentiate wires of varying diameters within the same layer using "/". Example: natural fiber core Walinzon rope: 6(6/6+6+1)+NF.
For special-shaped ropes, append the relevant symbol to the stock count. Example: natural fiber core triangular rope: 6V(9+12+1V)+NF.
3. Marking for Triple-Lay Wire Ropes:
Begin from the exterior, noting the total number of sub-ropes, then mark the sub-rope structure in parentheses. The full name for a triple-lay steel wire rope is marked as: 6[6(6+1)+NF]+NF, with the abbreviated form: 6×6×7+7NF.
4. Marking for Braided Wire Ropes:
Similar to double-lay ropes, but precede the total number of strands with "Y". Example: full name of a braided rope: Y8(12+6F+6+1).
5. Marking for Flat Steel Wire Ropes:
Similar to triple-lay ropes but add "P" before the total number of sub-ropes. Example: full name of a flat steel wire rope: P8[4(6+1)+NF]; abbreviated form: P8×(4+7+NF).
6. Abbreviation Marking for Wire Ropes:
Simplify by separating the total number of strands from the total number of wires per strand with "×", then separate the core code with "+". Example: abbreviation mark: 6×7+NF.
For wire-contact ropes like Xilu ropes, use "S", "W", or "Fi"; or mark the mixed/composite structures afterward. Example: metal rope core Varintoshilu rope: 6×41WS+IWR. Another example: braided rope: Y8×19Fi.
7. Marking for Surface Contact Wire Ropes:
Similar to double-lay ropes but precede with "T" and the total number of strands. Example: fiber core surface contact rope: 6T(6+1)+NF; abbreviated form: 6T×7.
In summary, understanding wire rope markings is essential for selecting the right product. These labels help identify the specific type, construction, and core material, ensuring proper application and safety standards.
