When do we talk about heavy loads?
In the heavy-duty sector, industrial areas and airports in particular are taken into account. According to EN 1433, this includes classes E600 (with a test load of 60 tonnes) and F900 (with a test load of 90 tonnes). The loads reach their peak in these areas. For example, drivable drainage channels have to cope with the weight of lorries that reach the maximum permissible total weight of 40 tonnes (44 tonnes in combined transport). However, there are also significantly heavier vehicles, such as container stackers or construction machinery such as crawler excavators, which can weigh up to 100 tonnes (wheel load 25 tonnes each) or more. It is not only the maximum load-bearing capacity (static load) of the drainage channels that plays a role here, but also uneven load distributions (dynamic loads) at high utilisation frequencies, which place additional stress on the material.
Reach stacker with a dead weight of approx. 78 tonnes above the HYDROblock drainage channel.
Example: Logistics area with loading ramp for lorries and 2% slope to the drainage channel.
Choosing the right trafficable drainage channels
If high loads are expected, the use of load class F900 in accordance with EN 1433 is particularly recommended. The test load for this class is at least 90 tonnes. However, load and trafficability are not the only decisive factors when selecting a drainage channel. Other important factors for optimum drainage are, for example, the size of the area to be drained, the expected water volumes and the nature of the surface.
