Not a practical way to get the people out...try firemen going up to
the control room and using the manual winch to bring the lift to the
nearest floor. ;-)
What if it won't move ?

Then the guy who designed it should be shot.
A lift does not get stuck,its the electrical circuitry that takes a
wobbler.
Stranger things have happened ...
Eg, Fork lift driver backs into lift doors which thereafter won't open
and also foul movement of the car.
I frequently see lorries stuck on the motorways because their brakes
have failed safe = on. Would firemen attack the brakes on a lift so
the could winch it down manually (If it were to happen, naturally).
3 men were killed in a mill where I once worked because they rolled a
large flywheel into a lift car which descended uncontrollably.
