Subject: tower erection
Content-Type: text/plain; charset=us-ascii
I know nothing about tower erection stuff. I saw your
e-mail address on Tower Talk.
I was wondering if I could pick your brain a little
bit, and if you can head me in the right direction at
least. Here it is:
A telecom company bought a pre-fabricated tower from
Central Towers (??). Central provided all the parts
and even delivered the kit to the site. Labor was not
While assembling/erecting the tower, a guy wire (??)
came loose from its 5/16 plate clamp, collapsing the
tower and killing the person on the tower. Come to
find out that the required clamp should have been 4/16
instead of 5/16 and that the 5/16 clamp was designed
for telephone poles and the like so that when a car
hit the clamp would give way and release the cable.
One engineer has tested the 5/16 clamp in question and
that result showed that the 5/16 held better than the
4/16. Is this misleading in some way?
Additionally, the plate clamp required 100 ft./lbs. of
torque. A crobsy clip requires only 15 ft./lbs. of
torque. No instructions, tools, or warnings were
given advising of the 100 ft./lbs. requirement.
Additionally a crescent wrench is the only tool used
in the field, and it cannot put 100 ft./lbs. or torque
on the plate clamp.
Is everything i'm saying correct? what are other
liability areas, if any of Central, in this fact
pattern? Further suggestions?
