Once all the sections of the flagpole are in the job site the first section, with the base plate is leveled and plumbed. Then all the other sections are inserted and welded with a very careful alignment.

For this operation you must have the necessary space at the job site, because the flagpole has to be assembled over the foundation.


 

 

The housing for the elevation mechanism is then installed, oriented in the same direction of the prevailing winds. At this time the obstruction lights and the lightning arrestor are installed.

The welding of the circular rings and the plug welds have to be done with extreme care to minimize the distortion caused by the shrinking effect due to the welding.


 

When the assembly is finish, the erection device is installed and welded, exactly above the anchor bolts.

This device is installed some feet above the center of gravity, to maintain the bottom part heavier.


  The cranes are placed in position and the rigging of the flagpole in one section begins.
