[0002] The elevator buffer is a device installed in the elevator pit to mitigate the impact force during elevator operation and protect the safety of the elevator and passengers. When an unexpected situation occurs during the operation of the elevator, the buffer will absorb part of the impact force and reduce the damage to the elevator itself and passengers.

[0003] Buffers are divided into energy storage type and energy consumption type. The former mainly uses springs and polyurethane materials as buffer elements, while the latter is mainly oil pressure buffers. Energy storage type buffers can only be used for elevators with a rated speed not exceeding 1.0m / s, while energy consumption type buffers can be used for elevators with any rated speed. The spring system of traditional energy storage type buffers is relatively simple, and is slightly inferior to energy consumption type buffers in bearing elevator pressure.
