Ethiopia Standard China Manufacturer Concrete Pole Machine

prestressed reinforced pole machine concrete pole making machine for sale

Overview of Prestressed Spun Concrete Pole Moulds
This Prestressed Concrete Spun Pole Mould is used for concrete electrical pole manufacutring. 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 the 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.
Our factory produces two categories of Pre-stressed concrete electric pole moulds, DMZ&DMD. The Prestressed Electrical Poles manufactured by this series equipments comply with national standard of JC/T364-2001.

Features of Prestressed Concrete Electric Pole Moulds
1 Welding technology, which enhances the smooth finish of the mould wall, and eliminates the uneven traces of rivet holes. So the concrete poles appearance will be improved significantly.
2 The cylinder is changed to U-type longitudinal stiffeners which can greatly increase the stiffness and flexural strength of the steel mould.
3 Install the slot with rubber sealing strip, in order to prevent leakage to ensure quality.

Main machinery for concrete prestressed concrete pole production line  



 

Centrifugal spinning machine for concrete poles and concrete pole steel mould for prestressed spun concrete electrical pole are two main equipments, which are used for producing prestressed and reinforced concrete poles and other cement products with a variety of different diameter and length.

 (1)overview of Centrifugal spinning machine 

 Centrifugal spinning machine for prestressed spun concrete pole is operated by remote-controlled continuously variable motor. It runs smoothly and has a variable-speed range. So the production of prestressed concrete pole are good quality with high srengtht.

The base of the machine is welded in box-type structure, sturdiness and durability. The bearings are well sealed and reliable, long service. Random electric control equipment is complete and easy to operate.

(2) overview of Prestressed Concrete Spun Pole Mould 

 Prestressed Concrete Spun Pole Mould is used for concrete electrical pole manufacutring. Its mainly manufacture technology is longitudinal tension by steel wires. During rotation of mould,  it can squeeze out the excess water contained in concrete under centrifugal force. Thus, it can greatly improve the concrete density and strength.

Technical parameter of prestressed concrete pole

Working Principle of   electric prestressed concrete pole making machine

1. Adding the slurry into the mould, it is driven quickly and rotated in the same speed of the machine. Each component is separated and released under the centrifugal force. Usually the higher the slurry rotate speed, the better the slurry separating effect.

2. Centrifugal sedimentation is the use of different density of each component in the slurry, which is rotated under the centrifugal force. To realize the liquid - solid (or liquid - liquid) separation.

3. The speed of separation is slow when the viscosity of slurry is high.

4. It is good for centrifugal sedimentation when the slurry density is different in each component.

Features of electric prestressed concrete pole making machine

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
