My guess is that there's some sort of velocity/acceleration threshold. So since the elevator car was still attached by other cables it didn't fall fast enough to trigger the mechanism earlier.
- busterarm 8y agoAs someone who was in an elevator that dropped ~20 floors out of nowhere and then functioned normally (Zeckendorf Towers), I imagine that's true.
- Someone 8y agoThat, and this was an express elevator, so safety features have to kick in at higher speed. Safety features also can’t decelerate the cage too fast. If, say, the elevator fell from floor 70 to floor 40 before safety features kicked in, it makes sense to use most of the remaining space for deceleration.
