General Information
- Abstract
This European Standard specifies the additional materials, manufacturing and testing requirements for full-locked coil hoist and half-locked and full-locked coil guide ropes for mine shafts to those given in Part 1.
The additional hazards covered by this European Standard are identified in clause 4.
For information only, typical breaking forces for both full-locked coil hoist ropes and half-locked and full-locked coil guide ropes, based on one particular combination of wire tensile strength grades in each case, are given in annex B (hoist ropes) and annex C (guide ropes) for some of the more common sizes of rope.

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.
- Materials and wire grades: Wire for hoist ropes must meet EN 10264-3; tensile strength grades for various wire components are defined (examples in the standard). Guide-rope wires follow the grades and tolerances given in Annex A.
- 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.
