Concrete Pole Spinning Machine Production Line

Products No. Hopeland A125
Name: Pre-stressed Concrete Spun Pole Production Line
Stuff Picture
This Pre-stressed Concrete Spun Pole Production Line is designed in accordance with annual production capacity of 36,000pcs various medium-sized cone pre-stressed steel concrete poles.
As far back as the 1930s, the People¡¯s Republic of China used armored concrete pole. With the rapid development of power industry, the production and use of concrete pole has developed tremendously thereupon.
Pre-stressed concrete pole develops rapidly because of much superiority. Compared with common concrete pole, its advantage is as follows:
Economizing steel in a large amount, about 30%~70% (adopting cold drawing can economize 30%~60%; in case of steel wire of high strength, economize 40%~69%);
Crack resistance is improved by 3~5 times;
Steel performance can be improved by 1~3 times;
Reduction of cost (adopting cold drawn wire can economize 25%~40%; in case of steel wire of high strength, economize12%~21%);
Good endurance can delay the appearance and expansion of cracks;
Protecting the environment that mankind depends on for existence, and reducing deforestation.
Pre-stressed concrete poles are strictly in accordance with two standards: GB396-94 Annular Armored Concrete Pole and GB4623-94 Annular Pre-stressed Concrete Pole of the People¡¯s Republic of China.
