Oil Buffer (Spring Outside); OH-70&220&275

The series are spring built-out hydraulic buffers. Used at the bottom of the shaft, they can be reset manually and automatically. If the elevator gets out of order and slides down, it will take the decelerating effect, and the knockout rod will trigger the switch, and then the safety circuit is enabled.
