LUZHONGBAO FEATURES

Product Description

Luzhongbao manhole covers are often made out of cast iron, composite materials. This makes them inexpensive, strong, and heavy. The weight helps to keep them in place when traffic passes over them, and makes it difficult for unauthorized people without suitable tools to remove them.

Luzhongbao manhole covers may also be made from glass-reinforced plastic or other composite material, not only conform to law restricting acceptable manual handling weights, but also have the benefits of greater slip resistance and electrical insulating properties.

A manhole cover sits on a metal base, with a smaller inset rim which fits the cover. The base and cover are sometimes called "castings", because they are usually made by a casting process, typically sand-casting techniques.

The covers usually feature "pick holes", into which a hook handle tool is inserted to lift them. Pick holes can be concealed for a more watertight lid, or can allow light to shine through. A manhole pick or hook is typically used to lift them, though other tools can be used as well, including electromagnets.

1. A round manhole cover cannot fall through its circular opening.
2. Round is the strongest and most material-efficient shape against the compression of the earth around them.
3. The bearing surfaces of manhole frames and covers are machined to assure flatness and prevent them from becoming dislodged by traffic.
4. Circular covers do not need to be rotated to align with the manhole.
5. A round manhole cover can be more easily moved by being rolled.
6. A round manhole cover can be easily locked in place with a quarter turn, which makes them hard to open without a special tool. Lockable covers do not have to be made as heavy to resist being dislodged.
7. A round flat metal casting will typically warp in its center leaving the rim flat and evenly supported.
