Hi,
I have two Tri-EX THD series towers and have had trouble with them
jamming when partially erected. I am thinking of putting a cable from
the top section to a pulley on the bottom section so that I could pull
down if necessary if it gets jammed again. I have read of a thing
called a "positive pull down" on some crank up towers, and would like to
see some photos of it before I do my thing, in case I'm missing
something, and they have a better way of doing it than I am envisioning.
Does anyone have any photos of a "positive pull down" mechanism?
Thanks & 73,
Rob, KL7NA
