Manhole Cover

Manhole covers are used on top of sewers, electricity or any underground services, which require regular checks or even just a simple adjustment.

Round covers cannot drop through the hole which they occupy and this makes them more safe and ease to maneuver.

They are employed for the purpose of gaining access to sewers, electrical vaults, storm drains, telecom system etc, to help in maintenance and in order to ensure safety.

These include the pedestrian covers, smaller ones in residential areas and the large ones in commercial areas which bear the bulk of the traffic load.

They are normally produced using some casting methods with materials such as, steel, or composite material.

Typical materials used are cast iron, steel, other composite materials such as reinforced concrete and polymer concrete.

Manhole covers are made to be waterproof, it means that the manhole covers seal the utility pipes against water leaks.

Depending on the size and type of equipment, their weights range from a few kilograms to several hundreds of kilograms.

Manhole covers are typically sealed with tools such as hooks, lifting keys, or hydraulic lifters.

Manhole covers are fabricated by companies dealing with the manufacturing of metals and other construction materials.
