The elevator is an indispensable vertical transportation tool in everyone's life, so everyone also knows that the elevator will fail, and the elevator will also have hidden dangers, so what are there?
Falling: There are two situations, one is the elevator free fall, which is very dangerous, but this situation is rare because each elevator is equipped with multiple brake valves. The other is that the elevator fails to slip and fall, sliding directly from a high place to the grass-roots level. This is very scary, but the elevator is only running at fault, not the car falling.
Rusking to the top: the elevator car in the case of all the control system failure, quickly rise and hit the top of the elevator shaft, and then stop or fall down, for a serious accident.
Shear: when the elevator door is opened, the car suddenly moves, if people are in and out of the elevator, they will be cut.

Pinch injury: In the process of opening and closing the elevator door, a force of about 15kg is generated. Put your hand on the door, or forcibly enter when the elevator door is about to be closed, you may be pinched.
Fall in: the elevator car is not in the flat position when the elevator door is opened, and passengers will fall into the hoistway if they are not careful.
Roll injury: passengers' hands and feet or articles are involved in the elevator door of the straight ladder, the gap between the steps of the escalator and the apron board. Although these gaps are small, they are the most lethal places of the elevator.
