That picture of the guyed tower structure looks very similar to the Constam T-bar that used to operate at Cliffs Ridge (now Marquette Mountain in Marquette, MI, USA). The sheaves were not rubber lined. There was quite a jolt and clunk-clunk sound as the T-bar passed over the sheaves. The Tees were horribly leaky things with an oil-damped shock and large external spring. Under certain weather conditions the Tees would freeze up (or require more force to extend) thus providing us with a thrill ride as we (as small children) were lifted several feet into the air for much of the ride (and sometimes spun around backwards).
Sounds exactly like the five old T-bars Sugarloaf/USA in ME used to have (and that's the same tower design). One had been replaced with the Double Runner chair by the time I started skiing there, and two others upgraded to reel-type Ts (is there an official name for these?). Those old telescopic Ts on the long, slow #5 T-bar would lift up small children even when they weren't frozen up. All are now gone except #3 (Bateau), which provides upper-mountain access on windy days (and has updated sheave trains etc.).
I think Pleasant Mountain (now Shawnee Peak), also in ME, used to have one of those chairlifts. They certainly had an ancient double with guy-stayed portal towers and no safety bar the one time i was there (in 1977). They'd retrofitted it with actual seat belts.
