290HC Mast Section Selection of Standard Festival for Tower Aircraft
As one of the basic components of tower crane, standard section plays an indispensable and important role in tower structure. A good standard section not only improves the flexibility of these heavy machinery, but also improves the efficiency of the work. Therefore, the selection of the tower standard festival is of great significance.
First, when selecting the standard section of a tower machine, we should look at the security labels that have not been affixed, or our own security marks that have been affixed by the regular manufacturers. If not, such relatively crude, unreliable, and unable to withstand long-term use. So do not covet cheap, durable is the hard truth.
Secondly, when checking the sample, we should look at whether the standard section of the tower crane is smooth and delicate. If so, it is generally more sophisticated and the processing and production are relatively in place. The standard section of the tower crane is not accurate.
Third, in the near view of the standard section of the tower hanging, it should also be seen whether the connection is good, whether the joints are flexible, lubricated, if rust occurs, or the connections are relatively slow, such a standard section is best not to buy. Because most tower machines have limited maintenance times, and the environment where the sun and rain and salt and alkali(such as cement) corrosion are severe on the construction site, the tower standard festival must face many tests. Therefore, when selecting the standard festival, only careful and careful can really achieve good results.
