The different load classes of manhole covers
Manhole covers are divided into different load classes in accordance with DIN EN 124 and DIN EN 1229. Our heavy-duty cover type HS14 is certified according to load class F. This makes it suitable for airports and other particularly high wheel loads.
Note: Heavy-duty covers are heavier than regular manhole covers in order to withstand the special loads. With the help of our hydraulic opening they can still be operated by a single person in an emergency without the need for additional equipment.
