This drive terminal was added in 1991 when the lift went from a double to a triple.Lift overview.Riding up.Some towers are Hall with Hall sheaves while others are CTEC with CTEC sheaves.A CTEC tower with Hall sheaves on one side and CTEC on the other.The return terminal went mostly untouched during the renovation.Upper terminal overview.View down from the mid-station.Lower part of the line.Tower 1 and the bottom station.View up at tower 3.Arriving at the top terminal.Another view of the tension system.View from near the summit.
I believe the CTEC towers were installed before the new drive terminal and upgrade to a triple in 1991 as they look to be of the older design that CTEC obtained from Thiokol rather than the newer style that was in production during the late 80s and early 90s.
I was referring to towers like the one in the 5th photo. The tower tubes may be original Hall but the crossarms look like CTEC replacements to me. There are also several fully Hall towers.

Those are Hall towers. Peter mentions that in his captions.
