> make the engine weak enough that it can’t do major harm. This doesn’t make sense to me. Outside of sensors that can automatically shut the motor off, the motor is definitely strong enough to do major damage in an unlikely crushing incident - it could easily sever or otherwise destroy a limb without even slowing down the carriage. The motor in any elevator has to be extremely strong: it’s not like paternosters slow down due to strain when people enter them. To put it a bit gruesomely, the motor doesn’t notice the difference between lifting a 100kg passenger or applying the same amount of shear force to a trapped arm.
