I'm not sure, I think it's a CT22 or something like that? I have 2 other cars at another building that I think are CT22's.. not sure, I'll check tomorrow. One thing about the machine, the sheave is hanging in the air on one side, no pedestal on the left side looking at machine from the front. I also noticed that the brake "relaxes" as it's coming into the floor. EVERY time the car has shut down it's been about 3" above the floor. I'm assuming it's trying to level in as the brake is "relaxing".
