uptime's connected device, directly plugged onto the elevator control card, allows all the faults detected by the machine to be analyzed in real time. The data is then standardized in a multi-brand format and sent to the stakeholders of the elevator. uptime's artificial intelligence makes it possible to offer maintenance recommendations to both the technician and his supervisor, who can then follow the evolution of the situation from their own platforms. 👇
 
 

Tracked faults:

uptime's technology traces elevator faults in real time, records them and analyzes them to provide maintenance recommendations. We have the case here of an elevator showing faults related to the elevator doors:

A fault indicating that the door is opening too slowly is activated (blocking fault after several appearances) appears 5 times on the sixth floor in the space of a few days.

A fault indicating that the door is closing too slowly is also activated (again, blocking fault after several appearances), it appears 17 times, still on the sixth floor.

 

💡 Conclusion:

The 6th floor landing door shows signs of weakness. This conclusion is all the more probable as the door sends faults on opening as well as on closing (which excludes the user as the cause of the problem).

 

Maintenance recommendation:

A maintenance recommendation is then proposed by uptime:

Take the brand's diagnostic tool when needed. The latter may be able to provide additional details once connected to the diagnostic port.

Perform a check on the sixth floor door lock.

Take spare lock rollers before setting off if replacement is necessary.

⛑ Recommended action:

We clearly identify the door of the 6th as faulty. However at this stage, it is still difficult to determine with precision the real origin of the problem. The technician is therefore invited to carry out a check on his next visit. It is recommended to use the brand's diagnostic tool (these can sometimes be more precise) as well as to take a spare part before the operation, just in case.

 

Result:

The technician can plan to verify this problem during their next regulatory visit, following the directions in the uptime recommendation. Arrived on site, he will indeed find a blocking problem preventing the proper functioning of the landing doors. 👇

As a nut was missing, the roller no longer held securely in place on its axis and moved when the door moved. When the roller got in the way, it produced resistance to the movement of the door (mechanical stress). The absence of a nut could have caused the roller to come out completely from its location and completely block the door, causing a failure.

 

A breakdown has been preventively avoided! 🎉

🏤 For the ops supervisor:

With his fleet monitoring software, the technician's supervisor has a fault counter for each of his elevators, which allows him to monitor the occurrences, the multiplication or the disappearance of these.

Three weeks after the visit, it is confirmed that the two faults had not reappeared. It can therefore be deduced from this that the technician's action made it possible to avoid a breakdown and to solve the problem.
