There are 2 elevators on one end of the building, one serves 13 storeys and one serves 12 storeys. This is because there is a pool on the 13th storey on top of one of the elevators so it couldn't extend to that level. The building manager said that because of the different heights of the elevators they cannot be controlled using the same system. But people tend to press the call button on both elevators and take the fastest one to arrive, so energy is wasted on both elevators working when only one is needed.

I was wondering if this is really the case that the elevators cannot share a same control system? Or is there any particular control system that can solve this problem?

Thanks in advance! Looking forward to your replies smile


With old relay logic or the newer electronic control anything can be achieved. What you describe is virtually the same as a basement level opening that is only served by 1 lift except your situation is at the top of the building. It appears to me as it was simply easier, or maybe they were lazy, to have 2 separate control systems for these 2 lifts. So the answer is of course you can and there is no reason why if your going to upgrade them that this cant happen.
