Wanted to follow up with the failure I had with my tower base. After several
conversations with US Tower, the tower and base in question is actually not a
US Tower brand, but looks to be an older Tristao. I believe the model number
is HMS-671 and is 35-40 years old.
US Tower was great to work with and they did offer a discount to repurchase
some of the parts I need to repair the raising fixture which was retro-fitted
to work with the Tristao tower and base.
I'm now installing a new HDX-589 in its place. I did update my web site with
the trashed M2 10M7 which is already on order and should be here by end of the
month.
Thanks for all the feedback and comment on the weld that broke on the base.
At 35-40 years old...I'm not sure what the QA process was back then, but I'm
just glad it failed the way it did. Things could have been much worse.
Thanks...

Subject: [TowerTalk] Failed HDX572 Raising fixture Leg and base
This morning I was lowering my HDX572 and as it was almost down one of the base
ears that the raising fixture leg mounts to failed. Fortunately it was a slow
drop and the tower is still ok. If it failed while it was higher this could
have been a different story.
I will need a new raising fixture and a new HDX572 base. I have a like new
spare TRX-80HD raising fixture for my HDX589 so I should be ok there.
I posted some pics and will add more later today. From the looks of the break,
I am seeing rust (Not clean metal) where the welds were. Also I'm not sure if
the ear on the one leg that mounts to the raising fixture began to bend first
or not. But it is bent a hard 90 degrees now as you can see.
Anyone else see something like this in the past? This is an older US Tower so
I'm not sure if the bases are built better now or not for the mounting ear.
