Rick,
The link from the top of the derrick to the tower (lifting component) is a
steel cable so practically no stretch here.
Regards,
Mark, K1RX

This is obviously a successful set up, but one thing
that I don't like is that the derrick is rigidly coupled
to the tower. I tried this years ago and discovered that
if the rope between the tower and derrick has any stretch
in it, you can end up with a lot of strain on the
connection between the pieces. What I do instead is
have independent pivots for the tower and derrick.
Then the ropes are non critical.
