A Fundamental Study Concerning the Correct Performance of Elevator Buffers

Osamu Furuya, Naoki Fujiwara, Satoshi Fujita


Various safety devices are provided to ensure the safety of the lift passengers. A number of safety systems are employed to prevent injury in case or uncontrolled movement.  The car and counterweight buffers (shock absorber) play an important role. This paper considers appropriate performance of the car and counterweight buffers.  Buffer performance is examined to satisfy a safe condition in the revised JIS A 4306.
