At EES Limited we are regularly asked to carry out works with minimum disruption to the end users which from time to time means weekends and night working. In one recent case a lift in student accommodation was makng a lot of noise and was desperately in need of a quick turnaround repair. We were asked to investigate, upon which we diagnosed a fully collapsed bearing to be the main issue.
On removal of the shaft, it became apparent that the shaft had suffered sever scarring from the lift being operated in this condition and would therefore also require replacement. As the lift repair required a quick turnaround sourcing a replacement shaft from the manufacturer was not a viable option so we had one manufactured in our workshop ready for the return to the site the following evening.
Notice the gaps between the pulley and the support plate (left hand image). Top and bottom gaps are very different due to wear in the bushing. The image on the right shows the replacement bushing made by us just before the pulley was re-installed on site.
As this work was all undertaken at night over a weekend there was very little disruption to the otherwise busty Student accommodation block.
