There are two main types of buffer for elevator: energy storage type buffer and energy dissipation type buffer. The accumulator type buffer is a spring buffer, the main component is a spiral spring made of round or square steel wire. Conical springs are rarely used at present.
The accumulator type buffer can only be used for the elevator with the rated speed of not more than 1.0m/s. The energy dissipation type buffer is suitable for any elevator at the rated speed. Buffer should satisfy: when the rated load carrying car free fall, and the impact velocity in order to design the buffer to buffer when the average speed should not be greater than 1G, less time faster than the above 2.5G should be less than 0,04s.
Buffer is an elevator safety device which provides the last safety protection. It is installed in the bottom pit of the elevator shaft, which is located in the car and the bottom of the weight. When the elevator is in the upward or downward movement, due to the failure of wire rope traction, friction brake system fault, lack of power and control system and terminal station beyond the bottom or top layer, the buffer buffer, in order to avoid the elevator car or counterweight directly hit the bottom or top, protect passengers and equipment safety.
