Wire ropes & rope break protection on sectional doors – select safely & replace correctly
Is your gate crooked? Jerky? Stopping? In 10 minutes you'll know which wire rope set fits, when the safety cable breakage protection is due – and how your system can run smoothly and safely again.
Introduction
Wire ropes transmit the force of the springs to the gate leaf. If they fray, stretch, or are incorrectly routed, the gate will tip over – the safety cable breaker engages, and the system locks. The good news: With the correct cable set (3 mm/4 mm), proper routing, and an intact safety device, this can be quickly remedied. This guide explains identification, selection, and installation checks – with verified product links to Tormeister 24.

✅ Advantages & Benefits
New ropes and intact securing devices prevent tilting and consequential damage.
Even cable tension protects rollers, hinges & drive.
Insert the appropriate cable set, check the guide – the gate runs smoothly again.
⚙️ Technical Background
Wire ropes run over drums/swivels to the gate leaf. Unequal lengths → misalignment.
Typically 3 mm/4 mm; galvanized steel, often with a PP core for dimensional stability and flexibility.
Triggers when a rope breaks or becomes severely slack – blocks the gate leaf.
Working on springs/ropes should only be done with expertise and the right tools. If unsure: consult a professional.
🧭 Selection & Identification
- Diameter: 3 mm for lighter gates, 4 mm for heavier gates (refer to manufacturer's specifications).
- Length & Connections: Set left/right, with/without thimbles – matching the fitting.
- Compatibility: Match the rope design to the drums/rope paths.
Tip: Send us a photo of the drum, rope end & pulleys – we'll match the set.

🔧 Application & Checks after the Exchange
- Always swap ropes in pairs (left/right).
- Guide the ropeway: no intersections, clean run-on onto the drum.
- Check the cable break safety device for proper function, reset if necessary.
- Open the gate halfway: it must neither fall nor rise.
- Even rope tension, no strand breaks.
- Check roller bearings and hinges (replace if necessary).
Stop assembly if you notice any abnormalities on the springs/bearing brackets. Send photos – we will recommend the appropriate set and the next steps.
💡 Practice, Acknowledgements & Mini-News
Misalignment caused by a stretched 3 mm cable. Replacement with a 4 mm set + safety check → smoother operation, drive relieved of stress.

❓ FAQ
How can I recognize worn wire ropes?
Fraying, broken strands, uneven running on the drum or misalignment of the gate leaf.
3 mm or 4 mm – which fits?
3 mm for lighter goals, 4 mm for heavier goals. Check manufacturer's specifications – we can help with matching.
Do I need to replace both ropes?
Yes, always set by set. This ensures that lengths/tensions remain identical and the movement is smooth.
Rope break safety device triggered – what to do?
Fix the cause (rope break/slack rope), check/reset the safety device, perform a functional test.
Replace it yourself or have it done by a professional?
Replacing the rope is possible; however, if you have any questions or require spring work, please consult a specialist company.
