Hi Tony -
Some time ago I tracked a 60 foot pole. It worked fine but then I
"inherited" a tower.
I haven't seen the track/ "carriage" you reference but it sounds like a good
starting point. However, don't loose track of the torque the antenna will
subject the track to. Perhaps matching cross bars on the tower and carriage
that could be bolted together when the carriage/antenna is up and in place.
I used nesting channel beams,but still bolted them together. I also
fabricated a cap for the top of the pole that incorporated front and back
sheaves to handle the hoisting cable.
Good luck with your project.

I have a old EZ-way tower (RBX-50) and NO WAY would I
use any kind of plastic/nylon pulley on that lift system!!!

Charlie is correct . i have a 40 foot pole the power company installed a
few years back when they put in the drop . they installed the drop going
under my extented 70 ft tower with a 4 ele quad.. when i got home i was
amazed they had done this.. could not crank the tower down. called the
power company they set a new pole and moved the drop. but left the old
pole. told me i could have it.. well i am looking at putting barn door
track up one side and a wench on the other. and putting my spare CL-36 on
it. finding a saddle type pulley has been a problem to go on top of the
pole. i think i have found a good one at grangers. that will bolt to the
top of the pole but i will have to make a cable keeper to go over the top
so the cable will not come out if slack gets into in some how. they also
have a small 4 pulley trolley assmy that will ride in the barn door track.
and will mount to a mast plate for the rotor.. now to find some heavy
duty barn door track in the area ..
