EN124 Standard
Surface manhole covers installed in Europe should meet the requirements of the European Standard EN124 : 1994. Products designed to EN124 are grouped depending on their place of installation.
Load Classes
1. 15kN
Pedestrians only areas
2. 125kN
Footways, pedestrianised areas, car parks
3. 250kN
Kerbside channels
4. 400kN
Roads, carrying fast moving, heavy vehicles
5. 600kN
Very heavy wheel loads as found on construction sites, mining and industrial areas
Can AX-S™ B125 Covers be used in areas accessed by HGV traffic?
This table demonstrates that B125 covers of BS EN124 are suitable for use in any area subject to slow moving vehicle traffic including HGV’s.
| Maximum European gross vehicle weight | 44.000 tonnes |
| Maximum gross axle weight | 11.500 tonnes |
| Maximum wheel load - assuming single wheel per axle | 5.750 tonnes |
| + 10% for overloaded vehicle | + 0.575 |
| + 15% for slow moving wheel load | + 0.949 |
| + 60% for margin of safety | + 4.364 |
| Total slow moving wheel load | 11.638 tonnes |
| Test load of B125 covers | 12.500 tonnes |
Access Chamber Standards
Unlike for manhole covers, there is no European-wide Standard for preformed access chambers. CUBIS has created its own vigorous range of tests to replicate a range of scenarios our chambers may experience when installed. Some of these tests have then been applied on a cyclic basis to further demonstrate our products resilience and strength against site conditions.
Wherever possible these tests have been carried out and verified by NAMAS Accredited test houses.
