The elevator has multiple safety devices, but there are many places where problems are easy to occur.

1 electrical safety device failure

2 insufficient braking torque

3 insufficient traction

4 speed limiter failure

5 safety gear failure

In addition, failure to comply with the rated load capacity (occupant number) of the elevator is seriously overloaded, or the deviation of the estimated load is large and the overload is delayed, which may cause the bottom of the elevator to occur.
