Challenge
As this was the only elevator that serviced the building, the challenge was to complete the upgrade with the minimal of down time for the elevator. The modernisation was started to coincide with the summer months. Refurbish work was carried out on weekends and weekdays between the hours 6pm – 9pm so it would not impact on the business in the building. The shutdown period was reduced to 2 weeks while the old motor and gearbox was removed, new motor and gearbox installed, new traction ropes installed and new electrics and electronics systems brought online.
