...oh, I meant castle drawbridges. I don't quite know if bridge drawbridges operate the same way? I should look that up.

But castle drawbridges are counterbalanced so their natural, neutral state is "up", for obvious reasons, and elevator counterbalancing works about the same way, I'm told. If the safety features were to catastrophically fail - which they wouldn't*! - then the elevator would go up.

* They really wouldn't. People are so scared of elevators crashing that multiple redundancies is the name of the game. Eight ropes, every one of which is capable of holding up the entire elevator and cargo alone, plus safety brakes. The guy who popularized elevators ran regular stunts where he'd be in an elevator in a scaffold and all the ropes would be laboriously sawn through, and then the public could see the elevator didn't move a notch despite all the ropes being broken. Which they wouldn't ever be, because there are eight of them.
