How to open the ductile iron manhole cover? On this issue, I have collected some information for you and integrated it. You can understand it through the article.
There are several kinds. Some nodular cast iron manhole covers have hinged (Hinged manhole covers) and some don't. You can use an iron rod (or a larger screwdriver) that can reach into the manhole cover hole to "don't" into the hole, and then pull it up. When there is a gap between the cover and the cover edge, insert something to cushion it, and then lift it up and open it by hand when you can reach out.
The iron hook extends down from the handle hole of the nodular cast iron well cover, hooks the bottom of the well cover and lifts it hard. If it can't be opened, pry it with a crowbar. If it can't be opened, buy a cover opening tool.
There are two holes in the nodular cast iron well cover. Insert the crowbar (iron bar and steel bar can be used). When prying, tilt it. Pry it up a little and move it.
Warm tip: as the nodular cast iron manhole cover is very heavy, you must pay attention to it during operation. Another thing is that you should not open it and steal it unless you have to. This is wrong. If it is necessary to open the well cover, it must be allowed by relevant departments and guided by experienced people on site.
