Principle and configuration
Principle of electric flagpole: A set of electromechanical flagpole drive movement is installed inside the electric flagpole. In the process of work, the flagpole drives the machine core to lift the flag to the designated position at the top of the flagpole instead of manpower.
360-degree downwind spherical crown device: the application of flagpole technology aims to prevent the red flag from folding or even knotting under downwind and headwind conditions. The device has high design precision, flexible rotation and long service life.

materials classification
stainless steel flagpole
According to the material, 20 1# or 304# and 3 16# stainless steel can be selected.
The development history of stainless steel flagpoles can be divided into three generations, the first generation is a common variable diameter flagpole, the second generation is a tapered flagpole, and the third generation is an electric remote control flagpole.
manufacturing technique
The traditional variable diameter flagpole is composed of three circular tubes of different sizes, which often break at the joint. There are three commonly used reducing pipes: 10 1mm-89mm-76mm, 89mm-76mm-63mm, 76mm-63mm-50mm and so on.
In the manufacturing process, different reducing heads are welded by argon-fluorine and then polished. Flag rope, as one of the necessary spare parts for raising the flag, needs to be lifted and slid for a long time, which has a little big restriction on the material. At present, there are red nylon ropes and stainless steel wire ropes, which are more reasonable in front and more expensive in the back.
