Steve, actually, these exist.
A local ham has a crank-up that has some sort of flip-over device at the
end of each section. It locks the next section to the previous one and
takes the strain off the cable.
This particular type of crank-up is DESIGNED to be GUYED. Because of
this, the flip-over devices convey the guy tension directly from section
to section, and do not put the guy tension on the crank-up cable.
Now, such a crank-up cannot be easily raised or lowered. It is intended
to be lowered only for antenna maintainence. Not approaching weather.
