[TowerTalk] Tri-Ex THS-471?

[Bill Winkis (Mindspring)]

I can find no reference to a THS-471 ... there is a HS-471, it's a 4 
section tower, crankup, with area measurement of each section at 
22",.....19 3/8".....16 1/2" ....and the top section at 13 7/8 
inches...these measurement are one side of the triangle measured from 
the inside to inside on the pipes.

extended height is 71" and nested at 21 1/2 feet..weight is 575 
pounds...It's a guyed tower, the guy kit is 120 pounds...all tower 
braces/struts are horizontal..no angles braces....

The cost of the guys $390.00..tower cost was $1177.00..Guyed the tower 
would handle 16 sqft ....

The 106 foot version of the HS series had a bottom section of 27 5/8 
inches...

Hope this helps..

As I remember the whole line of TriEx guyed towers, they made a set of sections from a few inches across to 24 inches or so.  The lineup was the T, THD, H, HS.  They just used the number of sections necessary for whatever height and width of sections you wanted.  So other than section width I don’t think the materials were any heavier.  But, you know what 50 years does to one’s memory.  Jim may remember some details about the HS model in particular.

> Howdy, TowerTalkians -        I'm trying to track down any info on the Tri-Ex THS-471 tower. Tashjian says they don't know anything about it. It's an older tower with no diagonal braces but is a little on the robust side so I think it'll handle a decent load but I need to find out what that load is. Any input appreciated.
