Dave's comments caught my attention, as I am about to buy, fabricate, and
install a new lift cable in a Haeavy Duty old Tristao Tower (Now made by US
Tower) The Tristao is a 3 section, 54 ft extended length tower. I am
llooking for the scoop on techniques for terminating the lift cable with a
thimble, and a crimp sleeve, something I used to call Nicopress. The old
Tristao tower cable's crimp sleeve is about 1.5 " long. This termination
has human life critical and tower life critical functions so i need to
recreate the termination properly. Dave distinguishes horizontal pulls,
from vertical, and differences in strengths of the termination. How do I do
a safe crimp to install the thimble?
For that matter, does any one supply premade properly terminated lifting
cables for a designated tower (Tristao 55' heavy duty)
