Unique Services & Applications (USA) had to completely rebuild the revolving truck systems a top of three 30' aluminum flagpoles. When USA first arrived we noticed that the truck systems were not revolving anymore and were frozen at one position which was causing the flags to hit each other and tear easily.
At further inspection, USA had determined that the aluminum spindle was so worn that it was causing the sealed bearings to warp and fall apart. USA then replaced the aluminum spindle with a stainless steel spindle and replaced all the sealed bearings and other hardware. Finally, the banners were installed and the revolving arms spun flawlessly once again.
