Puzzled? First of all, your tower is only rated for 50 MPH - not 76.
The difference in wind pressure is DRAMATIC - over double.
Second if that's really a Tristao tower, then it's getting long in the
tooth. I would estimate that it might be 15-20 years old or more. Plenty of
time for some deterioration in the materials.
Yes, file a claim with your insurance company and then have a
PROFESSIONAL tower crew come in and remove it. DO NOT attempt it yourself.
Welcome to crank-up reality. "Well, if I would've known that the winds
were coming in I would've lowered it." You shot yourself in the foot with
this one. Especially with towers lacking positive pull-down, you're SOL
trying to get it down in a wind. Good luck with your new tower.
