[TowerTalk] Re: Tower ID

[Pat Barthelow]

Thanks Roger for your valuable feedback.  I assumed a Tri-Ex tower because 
the tower trailer has a metal data plate riveted to the frame.  The data 
plate is not easily readable,(old, corroded)  but the words Tri-EX are 
visible and a partial word  'PORTA--'  Also a possible model number:  TRA8HD 
and a possible serial number of 54084.  (Could this thing have been built in 
1954?   Perhaps TriEx eqipped a Tristao Tower to its trailer.  I really need 
to positively ID the tower.   I have since looked again at the rollers..they 
actually appear to be steel, and so are their pin-axles.  I am impressed 
with how clean the tower is  wrt galvanizing and it's age.  The trailer, on 
the other hand, has a fair amount of   cleaning up to be done...

Pat, From all I recall, this is not a Tri-Ex tower but looks more like an
old Lou Tristao Manufactured Tower.
All Tri-EX towers I've seen used formed leg bottoms for guides and never had
anything like you describe.   No rollers anywhere, just bearings and pulleys 
for
the cables. All Tri-Ex towers also had all solid round "W" brace 
construction
throughout whereas this tower appears to use flat metal with raised edges 
and an "X" pattern.
Definitely not Tri-Ex. I do believe Doug, W9IIX has an older Tristao and you
may want to e-mail your message and photos to him at iix at w9iix.com and see
if he can I.D. it for certain. 73, -=Rog-K9RB=-

The tower is a fairly old Triex.  Triex has apparently evolved over the 
years into Tashjian towers.  The tower looks very much like an HDX  555  The 
trellis work (seen in the picture below)
should peg it.  The center to center corner distance on the bottom 20'
section is 24.5".

for a closeup photo of the rotor mounting plate, through the trelliswork.
