Dimensions of Changsha inverted ductile iron manhole cover with a diameter of 700 × 800 At present, the material of common manhole covers in the market is usually nodular graphite Cast iron well ring cover 。 Its size and national standard bearing capacity are heavy 400kN, ordinary 250kN and light 125kN. Dongsheng Hongyun ductile iron manhole covers have two ways, one is round, the other is square. The size of Changsha inverted type ductile iron manhole cover with a diameter of 700 × 800, generally speaking, in urban life, we choose a round manhole cover because it is not easy to tilt, which can better protect the safety of vehicles and pedestrians.
