What To See When Purchasing Manox Black Manhole Cover

Posted by Admin on March, 17, 2021

As black manhole covers age, they tend to become brittle due to nonstop exposure to the elements. Finally, they will break, particularly if they are made of cast iron. A broken cover allows drain odours to outflow from the underground drainage system and it poses a hazard to pedestrians and vehicles, so it needs to replace as a matter of urgency.

When purchasing replacement Manhole Covers, from its suppliers like Manox Black Manhole Cover sometimes called Inspection Chamber Covers, there are two key features to consider - size and loading capacity.

Points to be considered before buying manhole cover from Manox Black Manhole Cover Supplier


Manhole Covers are usually classified by their "clear opening" size - that is the size of the opening that they are made to cover. As any broken cover is nearly certain to have been in place for several years, it is very doubtful that a replacement cover will fit into the original frame. For this cause, all manhole covers are supplied with frames. The old frame will need to be detached by chipping away the surrounding concrete.

When this task is complete, you can see the size of the opening that is to be covered. Two dimensions are required length and width. It is generally best to take these measurements in millimetres, although most reputable manhole cover suppliers will show the measurement in both metric and imperial sizes.

Loading Capacity
For security reasons it is crucial that the replacement cover is fit for the purpose that is planned, and this is usually down to the area that the cover is to be fixed over, and the kind of traffic that will be using that area.

If no car or commercial vehicle can ever come into contact with the manhole cover, then a 2.5-tonne pedestrian cover will serve. This will normally be found in patios or garden areas. If the cover is in a driveway that is to be used by cars, a 5 Tonne cover should be used as a least. A 5-tonne cover will upkeep a slow-moving wheel load of 1.25 tonnes.

If a van or small commercial vehicle is expected to use the area, the load rating should be raise to 10 or 17 tonnes, which will support slow-moving wheel loads of 2.5 or 4.25 tonnes separately.

For commercial delivery access and pedestrian grounds, it is recommended that a 25-tonne cover is fitted, as this will care for a slow-moving wheel load of 6.25 tonnes.

For areas where expressed Lorries may be found, a 38-tonne manhole cover should be fixed. Forklifts exert an even better strain on manhole covers due to their fairly small tires, so it always best to check with your supplier before fitting a manhole cover in an area used by this type of vehicle.
