i visuallise a lift as a cage; a motor; a cable and a switch. why do
they get stuck?

why do they get stuck in between floors?

do you try to exit lifts stuck between floors? or do you fear
decapitation/amputation from a sudden motion of the lift?

thanks.


Lift have a built in safty mechanism such that if the cable breaks
(ie the lift freefalls, an automatic break is applied. (basically the
tension in the
cable stops some 'rods' from sticking into a 'grid' in the shaft wall..))

Known (at least in mining circles) as a "keps" (probably a corruption
of "keeps"), and usually operated by a centrifugal gizmo.
