Installation and Maintenance Precautions
| Component | Technical Role |
| Integrated Steel Element | Central or side-placed galvanized steel wire ropes that bear the mechanical load. |
| Conductor | High-flexibility Class 5 or 6 annealed copper (tinned/bare). |
| Insulation | High-grade materials (e.g., EPDM, XLPE, or Silicone) for electrical stability. |
| Outer Jacket | Heavy-duty PUR or reinforced rubber for extreme abrasion resistance |
Critical Selection & Usage Parameters
Breaking Load Calculation: Always confirm the total weight of the cable length plus the weight of any attached connectors/terminations. The steel core must have a safety factor of at least 3:1 for vertical hoisting.
Termination Methodology: Crucial Step. Never clamp the jacket. The steel core must be terminated using professional swaging or wedge-style grips specifically designed for the steel reinforcement.
Corrosion Protection: If operating in marine or humid industrial environments, ensure the steel element is galvanized or stainless steel to prevent internal oxidation.
Bending Radius: Because the steel core is rigid, these cables typically require a larger minimum bending radius compared to standard drag chain cables.
| Feature | Steel-Supported Cable | Aramid (Kevlar)-Supported Cable |
| Tensile Strength | Very High | High |
| Weight | Heavier | Lightweight |
| Elongation | Near-Zero | Very Low |
| Best Use Case | Vertical lifts, deep mining, massive loads | Dynamic reeling, high-acceleration machinery |
| Corrosion Risk | Potential (if jacket is breached) | None |
Installation Essentials (CRITICAL)
Fixation (The Most Important Rule): You MUST use professional Wedge Clamps or steel-core grips to secure the cable by its internal steel reinforcement.
Uncoiling: Always use an axial rotating stand. Never pull the cable from the side of the drum, as this induces permanent torsional stress.
Torque Release: Before final termination, allow the cable to hang freely to release any residual twisting forces accumulated during shipping and installation.
Bending Radius: Due to the rigid steel core, observe the manufacturer's recommended minimum bending radius (usually larger than standard cables).
Monthly Maintenance Checklist
| Component | Check For | Action |
| Mechanical Anchors | Slippage or looseness | Re-torque or reset wedge clamps to ensure the load is strictly on the steel core |
| Outer Jacket | Cuts, swelling, or rust spots | Seal minor abrasions immediately; replace if steel core is exposed |
| Movement Path | Abnormal oscillation/swaying | Check for seized guide rollers or uneven cable tension |
| Connection Points | Corrosive "rust bleeding" | Inspect for moisture ingress; replace if internal steel shows oxidation |
Signs of Failure (Immediate Action Required)
If you see these, STOP operations and inspect:
Sheath "Neck-down" (Thinning): Indicates the mechanical anchor has failed and the cable is stretching under its own weight.
Rust Streaks: Indicates the steel core is corroding internally. Structural integrity is severely compromised.
Spiral Twisting (Corkscrewing): Indicates residual torsional stress; needs re-calibration.
