Here are some shots of some of the real antique freight elevators in the former MK&T railroad shop building here in town. An electrician friend is in there doing some work and kindly took some pics for me.
This one originally had a hydraulic lift beneath it.. not sure, but I think it was air over water.. I'm not real clear on how that operated. The plumbing is all still there, but they've disconnected all of it... uses a electric hoist mounted over the shaft now to do the work. Only has to lift it to the mezzanine up above.. used to be a machine shop up there. It's still usable.
This one is still in original condition, but inoperable. It may have been a hydraulic lift, too.. but they replaced that with this electric hoist way back when. The building is 1914. The dark color box covers the hoisting mechanism. The electric drive motor is visible.
This is a closeup of the control mechanism. I worked there for a while and casually glanced at this to see if I could get it up and running, but gave up and got the other one working instead. Looks like their was some sort of pneumatic system connected in there, too. Like I say, I didn't delve too far into that particular lift.
This shows one set of the two counterweights that counterbalance the weight of the platform. Both elevators had these.
