Cable Ramp Buying Guide: Events, Offices and Industrial Sites
Trailing cables are one of the most common causes of trip and fall accidents in the UK. Whether it's a stage power cable at a festival, a networking cable in an office, or a temporary power feed at a construction site, a cable ramp can eliminate the hazard while keeping cables accessible and damage-free.
Cable Ramp Types
Pedestrian cable ramps
Low-profile (typically 20–40mm high) with a single or double cable channel. Designed for foot traffic only. Available in rubber or polyurethane. Lightweight and easy to position.
Vehicle Cable Ramps
Higher load-rated ramps (from 5 tonnes to 40+ tonnes rated) with deeper channels to protect cables from compression. Essential for any cable crossing a road, car park or vehicle route.
Multi-Channel Cable Ramps
Available with 2, 3, 4 or 5 channels for managing multiple cables in a single run. Reduces the number of individual ramps needed and creates a cleaner installation.
Hinged Cable Ramps
The cover lifts to allow cables to be inserted without threading them through the end. Ideal for quick deployment at events or where cables need to be regularly added/removed.
Modular Cable Management Systems
Interlocking sections that can be built to any length, with corners, T-junctions and end caps. Professional installations at events and outdoor sites.
Load Ratings Explained
| Rating | Maximum Load | Application |
|---|---|---|
| Pedestrian | 0.5 tonne | Foot traffic only |
| Light vehicle | 3–5 tonnes | Cars, vans |
| Heavy vehicle | 10–15 tonnes | HGVs, lorries |
| Heavy industrial | 30–50 tonnes | Plant machinery, telehandlers |
Channel Sizes
Always check that your cables fit within the channel — compressed cables may overheat. Common channel sizes:
- Small channel (10–20mm dia): Extension leads, ethernet, audio cables
- Medium channel (25–40mm dia): 16A event power cables, HDMI, data trunking
- Extra-large channel (80–100mm dia): 125A 3-phase, thick armoured cables
Event Cable Management Planning
For outdoor events and festivals:
- Map all cable runs on your site plan before the event
- Identify all pedestrian crossing points and vehicle crossings separately
- Use pedestrian ramps for foot traffic, vehicle ramps where any vehicle will cross
- Colour-code ramps: yellow for general hazard, red for high-voltage
- Ensure end-caps are fitted to prevent tripping on exposed ramp ends
- Cable ramps must comply with the Event Safety Alliance guidance on temporary electrical installations
Health and Safety Requirements
Under the Health and Safety at Work Act 1974 and Workplace (Health, Safety and Welfare) Regulations 1992, employers must prevent slip and trip hazards. Cable ramps satisfy the duty of care for trailing cable management. Key HSE guidance:
- Cables should be routed overhead where possible
- Where cables must cross walkways, a cable ramp is the recommended solution
- Cable ramps must be bright/high-visibility colour to warn pedestrians
- Inspect cable ramps during events/shifts — they can shift position under traffic
FAQ
How heavy a cable ramp do I need for a car park?
For a general car park with cars and vans, a 5-tonne rated vehicle cable ramp is sufficient. If HGVs or delivery vehicles will cross, use a 10–15 tonne rated ramp.
Can I use a pedestrian cable ramp on a road?
No. A pedestrian cable ramp will be destroyed by vehicle traffic and will not protect cables from compression damage. Always match the ramp load rating to the actual traffic it will carry.
How do I stop cable ramps moving?
Most vehicle cable ramps have pre-drilled holes for optional anchoring with screws or anchor bolts. For temporary outdoor use, heavy rubber ramps rely on their own weight — lighter ramps may need anchoring.
