automatic Prestressed concrete pole mould

A prestressed concrete electric pole spinning machine is a specialized piece of equipment used in the construction industry to manufacture prestressed concrete electric poles.

Pole Cage Welding Machines are commonly used in the transmission and distribution of electricity. They are made by placing high-strength steel wires or strands inside Pole Molds, which is then spun at a high speed to create centrifugal force. This force helps to compact the concrete and distribute the steel strands evenly, resulting in a strong and durable pole.
The spinning machine consists of a rotating mold or formwork, which is driven by a motor. The mold is designed to have the desired shape and dimensions of the electric pole. The high-strength steel wires or strands are pre-tensioned and positioned inside the mold before the spinning process begins.
Once the spinning machine is activated, the mold starts to rotate at a high speed, typically around 60-80 revolutions per minute. The centrifugal force generated by the spinning motion compacts the concrete mixture and forces it against the inner surface of the mold. This process helps to eliminate air voids and ensure proper consolidation of the concrete.
During the spinning process, the pre-tensioned steel wires or strands are also stretched and anchored at both ends of the mold. This pre-tensioning helps to counteract the tensile forces that the pole may experience in service, making it stronger and more resistant to bending or breaking.
After the spinning process is complete, the concrete is allowed to cure and harden inside the Concrete Pole Mold. Once fully cured, the Concrete Pole Mould is opened, and the Precast concrete Cage Welding Machine is removed for further inspection and testing. The poles are then transported and installed in their designated locations for use in electrical power distribution systems.
Overall, the Concrete Pole welding machine plays a crucial role in the efficient and cost-effective production of durable and reliable electric poles.

Prestressed circle spun concrete pole moulds is used for concrete pole making. Its mainly manufacture technology is longitudinal tension by steel wires. Then it can squeeze out the excess water in the concrete under the centrifugal force. Thus, it can greatly improve the concrete density and strength.

 In order to form concrete more quickly to meet the design strength of more than 70%, steam curing can be carried out so as to shorten the mould-releasing cycle

1. Saving a great deal of steel, about 30~70% (employing cold drawn steel wire can save 30%~60%; employing high stress steel wire can save 40%~69%). 

2. Crack resistance can increase about 3~5 times. 

3. Rigidity increases 1~3 times.

4. Reducing the cost (using cold drawn steel wire can reduce 25%~40%; using high stress steel wire can reduce 12%~21%). 

5. Good durability, can delay the existence and expansion of cracks. 

6, Protect the environment on which human beings depend on for existence, and reduce the deforestation.
