A manhole cover is a detachable plate creating the lid on the top of the opening of the manhole. These are designed in a way to prevent anyone from falling in. If we go back to the Roman era, the sewer grates were built of lime sandstone. Now in this modern era, it has changed.
While working on the manholes, you must know there is a distinction between the manhole covers. Not every manhole cover is built equal. There are various types of covers and everyone has their place to work for. If you are required to decide on purchasing manhole covers then you will need to weigh where you want to install them. Be clear about what the manhole cover in the place has to deal with yearly. Have a glance at the guidelines for buying the finest manhole covers:
a) The capacity
The first and foremost thing to ponder upon while choosing manhole covers is - Capacity. The capacity means how much load can continuously cross or pass over the manhole cover. Suppose we take an example of - "C" class cover must be used where loads of the trucks or vans are over 10 tonnes. While class "A" is best for the pedestrian area and gardens because they have a capacity of around 2.5 tonnes. When you have manhole covers in the driveway, the finest is a class b which can efficiently support 5 tonnes of load.
b) The Standard or Quality
Whatever you purchase you will always wish for the best quality of product and, when you come to manhole covers it becomes mandatory for you to see and check the quality before buying. It is all about safety, security and avoiding accidents too. The composite manhole covers can last around 20 years with normal maintenance. Compare the manhole covers to 10-15 years of lifespan and see the advantages.
c) The Scrap Value
Few people can not understand but, manhole theft is a big problem. It often happens in a few places where manhole covers get stolen. The composite manhole covers have 0 scrap value so it means those are less likely to get stolen.
d) The shape
Measure the precise opening size which your manhole cover requires to take the calculation from manholes' inside walls from the other side. If the hole is rectangular or square, you will be required to take measurements of both the height and width as just opposite to the diameter or width of the circular manhole covers.
So, we can see a few things that have to be kept in mind while purchasing the manhole covers to offer stability and safety to people. The best safety measure is the manhole cover to restrain people from falling into the road manhole.
