Electric concrete pole machine/production line

A.Brief of Electric Concrete Pole

I.Electric Concrete Pole Look:

Electric concrete pole can be made in many shapes.Poles up to 40 feet long with square or rectangular solid cross-sections are easy to manufacture,occupy less room during transporation,and faciliate positioning of steel at corners for maximum resisting moment at a given depth.Circular hollow cross-sections are better for longer poles.Because hollow,weigh less.And because they are spun at high speeds in casting operation,then concrete is denser and stronger.

II.Working Principle:

Electric concrete poles generally are manufactured in centrifugal casting process.Centrifugal casting or spin casting is the best and cost-saving method for electric concrete pole production.In centrifugal casting,a steel form(mold) is placed on machine,partially filled with amount of precalculated concrete ,then spun for several minutes(time for spinning depends on motor speed).The tremendous centrifugal forces created by the spinning consolidated the concrete by forcing it against on the wall of the form.Excess water that is squeezed out of concrete is poured from the hollow cavity created in the center of the pole.After spinning,the form is steam cured until the strength of concrete is 3500psi.The prestressing wire is then released,and the pole is air-cured for 28 days.The result :a hollow pole made of dense concrete.

Specifications of Spinning machine:

2.Steel mould

The prevailing specifications of mould will be as below:

Steel Mould Specification

The raw materials of our mould meet international standard,so our finished mould has advantages of high strength,precision and non-deformation.

Each of our steel mould is mechanically processed by different machine tools for the purpose of decreasing deformation frequency,higher strength for different loading capacity of pole,and more precise of each part of mould.The mould processed by this technique will have advantages of long life- about 15 years,easy to operate- easier for workers to assemble two halves of moulds,non-deformation of mould,and the finished pole from this kind of mould will have a neat apearance
