Line Superintendent Report to IAECSlide2
The crew was doing a routine pole change out. They were
“lifting
” a pole
(
some of us may define it as pulling a pole). Slide3
The boom was nearly extended all the way out, therefore causing even more leverage on the boom.
No
overload protection devices operated prior to the boom failure. Slide4
My best guess as to the cause of the accident was boom fatigue over time from “pulling” poles and not “lifting” poles. I also speculate that the boom failed prior to the overload protection devices sensing the overload. Slide5
This is one of those events that no one is going to say anymore than they have to and management cannot prove otherwise. There was no push-back as it was made clear that all pole removals
require
the use of a pole puller.
It is
difficult
to say if our pulling/lifting actions were the cause or if there was indeed a premature mechanical failure of the boom. The possibility of
the
men or the truck manufacture coming forward to admit any fault is slim to none. Slide6
From today on
at “XYZ CO-OP”,
if another bent boom comes in, it will not be because of pulling poles and a very good, proven explanation will have to be provided as to why the boom is bent
.
DUECO was the manufacture.
Equipment is not designed to perform this task. Twin-screw
digger derrick
. Estimates are around $50,000. Slide7
WHAT ARE YOU DOING TO REMOVE POLES FROM THE EARTH?
Does your Co-op have an extra $50,000 laying around?
Should there be disciplinary action?
Is there a need for a policy change?
