Advantages of cast iron manhole covers in the transportation industry:
High strength and load-bearing capacity
· Cast iron manhole cover has high compression, bending resistance, impact strength and toughness, can withstand the repeated crushing of transport vehicles, and is not easy to crush or damage after long-term use, which can effectively prevent the "urban black hole" accident caused by damage to the manhole cover and ensure the safety of the transportation process.
· Different types of cast iron manhole covers are available to meet different load-bearing requirements, such as the manhole cover load classes specified in the European standard EN124, ranging from 15kN for pedestrians and bicycles only, to 900kN for large tyre load lanes such as docks, airport runways, etc., depending on the specific needs of the transport site.
Strong stability
· Due to the equal distance from the center to the circumference of the circular cast iron manhole cover, no matter how the vehicle rolls it, the manhole cover is not easy to tilt, shift or fall into the wellhead, which can better cooperate with the wellhead and maintain a stable coverage state, so as to ensure the safety of transport vehicles and pedestrians.
Good weather resistance
· Through scientific formula, advanced technology and perfect technical equipment, the cast iron manhole cover can be used normally in a wide temperature range of -50 °C ~ +300 °C, and adapt to various harsh natural environments and climatic conditions, such as severe cold, scorching heat, heavy rain, blizzard, etc., and will not crack and deform due to temperature changes or weather factors, so as to ensure long-term reliability in the transportation process.
Long service life
· Cast iron material has extremely high durability and corrosion resistance, which can prevent the erosion and corrosion of various chemicals on the manhole cover, so that its service life can generally reach about 15 years, reducing the frequency of manhole cover replacement, reducing maintenance costs and operational risks in the transportation industry.
Good anti-theft performance
· The cast iron manhole cover has no recovery value, natural anti-theft, and the locking structure can be set according to customer needs to further realize the anti-theft of property in the well, which can effectively prevent the manhole cover from being stolen and avoid potential safety hazards to transport vehicles and pedestrians due to the lack of manhole cover
