I must have missed this video, that is SO COOL! Interesting how they are using a drum, but they could have just routed the ropes over a normal sheave directly to the counterweight. A lot of winding drum machines don't have one.
Well, the size of this elevator cab might have been the reason a winding drum system was installed. However the installation likely could have been done with a geared traction machine with a slightly larger driven sheave, and smaller hoist motor. Since the machines were set at an angle, a defector sheave would have been installed for the counterweight ropes. 1:1 roping, Or if greater weight capacity was required 2:1 roping with compensating sheaves top of cab and counterweight, the free ends of the cables anchored to the top of the hoist way. Quite true, some winding drum elevators did not have a counterweight, ones I've seen in videos were basement machines.
Some nice industrial fixtures, but they seem a bit makeshift with those off the shelve cases around them. Looks like a one of a kind custom made job. The motor is quite heavy, I wonder why they choose a winding drum as late as the 50's. It has two sheaves, I suppose the smaller one is for the couter weight? The shaft is suprisingly bright and light it looks like the shaft lights are on permanently.
From looking at the roping in the hoist way and the ropes around the drum, the machine's mounting at an angle in the machine room. The yellow sheaves are defectors, leading down to the counterweight. I think maybe the difference in diameter between them might be related to maintaining tension/balance. Winding drum elevators were generally basement installations, depending on the building's construction.

Wonderful lifts..Very rare to see a winding drum machine..
