Hydraulic elevator modernization – Chicago, IL.

This is from a building that we just modernized.  The elevator was originally a Otis Elevator from 1965. We have previously replaced the cylinders in the building due to the City of Chicago cylinder mandate.  The elevator was in rough shape when we completed the cylinder replacement 3+ years ago.  When I went back to do the engineering the car ran like a cross between a haunted house and carnival ride. We did not maintain this elevator prior to modernization.

Elevator Controller – On this project we used a Smartrise Engineering hydraulic controller to replace old Otis relay logic control system.

Elevator power unit – We replaced the Otis dry power unit that was leaking everywhere that had a previous valve replacement with a MEI power unit with a  UC4 valve.

Elevator fixtures – We used Innovation industry surface mount hall stations to cover the existing fixture holes at 50”+ and bring the button down to 42”.  The car station has a digital position indicator, emergency light, emergency phone and ADA compliant buttons.  This building owner wanted a different type of push button style then we typically use.

Elevator door operator – We replaced the old Otis door operator with a new GAL MOVFR II.  We replaced all the car and hatch equipment with new Otis door parts.

I always like seeing the before and after of our modernization projects and see the dramatic transformation.  This elevator should be good for 20-30+ years.
