General Information
Overview
EN 12385-7:2002 - Steel wire ropes - Safety - Part 7: Locked coil ropes for mine shafts (CEN) specifies the additional materials, manufacturing and testing requirements for full-locked coil hoist ropes and half-locked / full-locked coil guide ropes used in mine shafts. It supplements the general requirements of EN 12385-1 and addresses hazards specific to locked coil rope constructions. Annexes provide practical data (typical breaking forces) and order/installation information.
Key topics and technical requirements
- Scope: Requirements specific to locked coil hoist and guide ropes for mining applications, with hazards identified in Clause 4.

- Wire finish and lubrication: Acceptable finishes include bright or zinc-coated (class D). Lubricants must comply with ISO 3156; friction hoist rope lubricants should also consider DIN 21258 to match sheave lining and friction characteristics.
- Rope construction: Defined constructions for full-locked coil hoist ropes, half-locked and full-locked guide ropes, including outer-layer wire arrangements and centre wire options.
- Dimensional and mass tolerances:
- Diameter tolerance: measured diameter within ±2% of nominal.
- Difference between diameter measurements: not to exceed 4% of nominal diameter.
- Length mass tolerance: ±4% of specified nominal length mass.
- Length tolerance: actual length ≥ specified and ≤ specified +2%.
- Breaking force and testing:
- Manufacturer specifies minimum breaking force; typical values shown in Annex B for reference.
- Spinning loss factors: 0.835 for full-locked coil hoist ropes, 0.925 for half-locked coil guide ropes (unless otherwise stated).
- Breaking-force tests per EN 12385-1 (Method 1) on samples from each production length.
- Verification and certificates: Visual inspections for lubricant/lubrication and construction; certificates must state measured diameter, measured breaking force, measured length mass and reel dimensions. Additional test results may be included.
Applications and users
EN 12385-7 is essential for:
- Rope manufacturers designing locked coil hoist and guide ropes for shafts
- Mine owners, procurement specialists and specifiers preparing enquiries and orders
- Safety engineers and maintenance teams responsible for selection, testing and inspection
- Testing laboratories verifying breaking force and dimensional compliance
Practical notes: locked coil ropes are often custom-designed for specific shaft conditions - purchasers should negotiate lubricant choice, joint requirements, reel limits and installation details per Annex C.
