Door Locks require maintenance on an ongoing basis. Let's face it. Elevator doors open and close hundreds of thousands of times in their life time. If the doors are not serviced regularly you will start having shutdowns, entrapments and at best intermittent interruptions in service.Minimize your repeat calls. Keep the customer happy. Make the time to perform this very basic service which consists of cleaning,lubricating,adjusting and replacement of worn parts.

So, on this elevator, the manual controls are inside the car? I always thought that they were on top of it.

Great Question.

Elevators are like automobiles;many makes and models. This old car has up and down inspection buttons behind a panel door.

Your complaint has validity and is not frivolous. Knowledge is Power.

You are quite welcome.

@ElevatorAdjuster Will tell them to mention that door to Otis the next time they show up. Thanks so much!

Sounds like there is more than just a spirator problem. This door needs to be properly serviced. Great observation! You'd make a fine elevator mechanic.

[thyssenelevator95]

@ElevatorAdjuster The spirator doesn't make the "flop" noise, but the door does have trouble closing once the vane detaches from the release assembly (which is when the spirator is crucial). When it does latch, the keeper makes this AWFUL grinding noise as it is *just* latching. When it doesn't latch, you hear nothing (aside from the "bell crank" on the 6940A hitting the tab on the switch box to retract it), and then you have to reopen the door or push it shut if you are outside the elevator.

Thank you for your question.

The answer is an absolute YES!

If the door closes with difficulty imagine what a draft running up the shaftway on a very windy or cold winter day would do. The tension needs to be increased. If the spirator makes noise " flop..flop...flop...flop...flo­p..." the spring inside the spirator is shot and needs to be replaced.

I have a really good question for you. Are the adjustment of spirators part of regular preventative maintenance? There's an elevator over at my grandma's (it's an Otis with the traditional 6940 lock) that has a door with a spirator that has little tension. It is so loose that it tends to not latch! Is this something that is serious enough to bring Otis in right away, or can it be mentioned the next time they show up for preventative maintenance?
