Manhole cover load classes
Choosing a manhole cover is not only about dimensions. The correct load class depends on traffic movement, installation location, and how the surrounding chamber and support structure are prepared.
| Class | Typical area | Selection advice |
|---|---|---|
| Light duty | Footpaths, gardens, low-risk utility access points | Choose when only pedestrian movement is expected. |
| Medium duty | Internal roads, residential premises, moderate vehicular movement | Suitable for sites where occasional cars or light vehicles pass over the cover. |
| Heavy duty | Municipal roads, industrial yards, higher traffic routes | Select for areas with frequent vehicle load, higher point loading, or stronger project requirements. |
What to check before finalising load class
- • Pedestrian-only area or regular vehicle movement
- • Light internal road or municipal road loading
- • Static machine movement or repeated wheel loads
- • Chamber edge support and frame seating quality
- • Project drawing, consultant requirement, or municipal standard
Common buyer mistakes
- • Selecting heavy duty without checking actual site need
- • Matching size but ignoring traffic conditions
- • Assuming chamber strength automatically matches cover strength
- • Using the same class for footpaths and industrial loading zones
Recommended next step
Once you shortlist the load class, match it with the right size variant and confirm the frame dimensions. For example, heavier traffic sites often need larger or stronger variants with better seating support.
