III. Technical Notes

1) Understanding of the Wind Resistance of Masts
Wind resistance of mast is one of the important technical indexes of mast products. Every customer wants to know how much wind power the mast can withstand after installing the load, but at present, few people can answer this question accurately. This is because the wind resistance of masts depends on the following three factors:
Material and Structure of A Mast
Use Height of B Mast
Weight, Volume and Shape of C Load
When all the above three conditions are clear, we should draw a conclusion.Mobile lifting pole, mobile lifter, mobile telescopic mast, mobile lifting tower mast, mobile lifting branchframeSpecific wind resistance index can be achieved in three ways:
(1) Finite element analysis is used for theoretical calculation.
(2) In the simulation experiment, the wind of different grades is converted into wind pressure, and then tested by physical method (tensiometer).
(3) The mast and load are placed in the wind tunnel to simulate the wind speed.
Among the three methods mentioned above, the third one can provide more realistic values. However, the cost and conditions of wind tunnel experiments are very high. For example, if a mast with loads is 18 meters tall and tested in a wind tunnel, is there such a large wind tunnel? Can you do it? How much does it cost? It's all a problem. Therefore, for the mast manufacturer, the wind resistance index of the mast can only be provided by the above two methods.
2) Calculating Method of Wind Resistance of Mast
(This calculation method is a theoretical calculation formula for mast without load, which is provided by experts engaged by our company, according to the material, structure and height of mast, for reference only.)
For example, the wind resistance of A4-270-2300-7600 lifting poles is calculated according to the reference wind speed of 100 km/h.
