How to choose a manhole cover load class for your application

Pedestrian areas, parking spaces and roads have different conditions. First clarify the location, vehicle loads and applicable standards.

Define the location before discussing the load class

Start with where the cover will be used. Pedestrian areas, residential parking, urban roads and industrial loading areas have different structural and load requirements. Consider the exact position, whether vehicles cross it and the standards specified for the project.

Dimensions mean more than length and width

Overall dimensions, clear opening, frame height and bearing-surface dimensions are different measurements. Provide opening and foundation drawings, tolerances and site conditions to reduce compatibility problems at installation.

Include site conditions in your enquiry

Prepare the location, expected vehicle types, clear opening, quantity and requirements such as anti-theft features, sealing and noise reduction. After a project designer confirms the standards, select products using defined conditions and drawings.
