Hello,
We have a four story building in Cleveland, Ohio. This building houses two 1929 Otis elevators both exactly the same. We are experiencing difficulty with one elevator. Upon being called, it vibrates severely. Fuses and coils burn out on a regular basis. We often, when going to the doghouse, find the nuts and bolts have loosened and wires have disengaged from their place. We also at times find the metal dividers between coils have disengaged and fell to the floor. We speculate that this is because of the vibration problems. We cannot pinpoint the cause of the problems but we think it may have something to do with the contacts. Event though, as mentioned above, we continue to replace fuses, coils and contacts the problem persists. We have had many service calls by licensed technicians who not only replace these items but work on the relay, cam arm and other mechanisms relating to the elevators service. However, the persists and we end up back at square one replacing coils, fuses etc.
Has anyone had this or similar experience with an older elevator. Any help or advice would be appreciated.
Thank you
