[TowerTalk] Your experience with rope capstan hoists or winches

[Wayne Kline]

John


 When I first used  a Greenlee Wire tug' er    it has no provision to tie the free end off and so you pulled a loop through a  tower rung and did a Halfhitch


the AB Chance units have either  a T handle  across the face of the transmission or a paper Clip U wire made from 3/8 Rod and you secure the  line with a  1/2 wrap and  clove hitch  or half Hitch

I wondered what would happen if the capstan operator had a sudden health
issue. I have seen a tower guy being pulled to the top with a capstan
winch. Many of us do not have a ground crew, if we're really lucky we get
a little unskilled help.  What happens of you want to leave the load in a
certain position for a while, do you tie the free end of the rope to
something?

Well they should not be operated while drunk or when texting, that's for
sure. Nor by someone with zero training.

When you have the proper number of wraps on the drum (when it takes approx
5-10 lbs of manual hold to stop the load from moving while the drum is
spinning), and the rope supply is in-line with the drum, you can let go of
the rope and the load will slowly descend. No free fall involved.

Chance now includes a safety device which prevents the rope from coming
off the end of the drum even if the rope supply is not in-line and the
operator has a heart attack.
