The transportation method and load-bearing pressure of ductile iron manhole covers. The ductile iron manhole cover is basically indistinguishable from the outside world, the difference is the load-bearing specification of the ductile iron manhole cover. In the production process, in order to better protect the environment, manhole covers obtained by high-temperature smelting and casting are required. The test load of ductile iron manhole cover is 400kn, corrosion resistance, aging resistance, corrosion resistance, toughness, long service life, high bearing capacity, not easy to deform, and safe.
The turning ability of the ductile iron manhole cover truck can only meet the application standard when it is very stable, and the strength and toughness of the product can reach the change of this state. Ductile iron two-layer left quiet manhole cover bears more than 360 kN seller or super steam -20 main vehicle.
Cast iron manhole covers provide convenience for everyone's manufacturing life, and there are many key points that must be paid attention to in the process of transporting cast iron manhole covers. If the cast iron manhole cover is damaged on the winding urban roads, it will greatly affect the damage of the cast iron manhole cover. Therefore, the correct method of transportation is the protective method of maintaining cast iron manhole covers.
Ductile iron manhole covers say that if an electric forklift is used to load and unload cast iron manhole covers, there should be a distance between the fork tines and the fork tines to prevent violent impact between the fork tines and the galvanized flat steel outside the manhole cover. During the installation process, large devices with mounting clips should be used to prevent them from falling. If the span between the boards is relatively large, a support frame can be used for installation. For cast iron manhole covers that are transported more, it is recommended to use lifting slings for packaging and lifting. The suspenders have moderate strength, which can ensure that the ductile iron manhole cover does not wear out. If galvanized steel wire rope is used for lifting and hoisting, attention must be paid to the galvanized flat steel at the edge of the cast iron manhole cover without wear.
