Hydraulic Elevator Modernization – ESCO Elevator – River Forest, IL

This project was at a building that was built in 1967 and the building was frustrated with the inconstancy of the elevator system and the longer and longer time it took to get a shutdown repaired and parts.   We did not maintain this elevator prior to modernization and worked with a building a year and half in advance of their modernization so they had time to get out of their existing maintenance agreement and the residents had time to prepare for the 4-5 week project.  

 Existing elevator & project scope – The existing elevator was an ESCO Hydraulic Elevator from 1967 with all of its original components still servicing the building.  It is always impressive to see a 50+ year old piece of equipment that runs well for its age.  Our scope was to replace all of the electrical and mechanical components of the elevator system with new.

 New equipment providers

 Controllers – Smartrise Engineering                                                                                   Power units – MEI                                                                                                                 Door operators – GAL                                                                                                          Fixtures – Innovation Industries                                                                                          Elevator cylinder - EECO

Machine room layout – One of the big challenges we have when working with older buildings is their existing machine room.  This machine room also includes other mechanicals or storage.  The project team and electrician where able to work together and get a good spot to get all of our NEC electrical clearances.  The old disconnect was tucked behind the elevator motor starter panel.

Hydraulic elevator controller – the original controller is an ESCO relay logic system.  Historically these will have open/close relay issues and general relay issues that require an old school relay tester for proper resolution.  We replaced this with a new Smartrise hydraulic elevator controller.

Hydraulic elevator power unit – The existing ESCO power unit was still there with a newer EECO UV5 valve that had been replaced 10+ years ago.

Door operators – Original GAL MOD operator was replaced with a GAL MOVFR door operator and car and hatch equipment.

 Elevator car station – The old ESCO fixtures from the original installation replaced with new Innovation car and hall fixtures.  We moved the location of the elevator car station to the return because the new car station is larger than the older one to meet ADA requirements and the side wall has a brace rod running diagonal preventing us reusing this wall.

Elevator hall station fixtures – The new main landing car station is packed with new devices and needs to be ADA compliant.

Take away – The elevator modernization was long overdue, most of the equipment was well worn and serviced the building for many years past its life expectancy.  We had a great leadership ground from the building to work with, a great property management team and our project teams did great on this.  14 people at Colley Elevator from the first phone call to the final inspection had touch points on this project.  At times, we forget that while we have a sales person and a project team there are many people in-between that help make this project a success.
