What this video shows
A day on the job at a downtown Chicago hotel, working on an elevator motor rotor, with a view from the roof before the work starts.
First the new bearing goes on the rotor, pressed just enough to hold it in place and keep it straight. Then the rotor is flipped and stood up, and a 75-ton hydraulic press drives the bearing all the way into the bearing seat. It takes precision and the right tools.
IRM handles elevator machine work alongside elevator sheave regrooving, mostly in buildings around Chicago.
