JHQ series elevator polyurethane bufferDetailed product description：

The JHQ series elevator polyurethane buffer is a safety protection device required for the elevator to operate to its extreme position. It can quickly convert impact kinetic energy into elastic potential energy and is an essential device used in elevators to ensure equipment and personal safety. At present, there are various forms of buffers in the elevator buffer market, such as spring buffers, hydraulic buffers, rubber buffers, polyurethane buffers, etc. Wanchun Technology has conducted in-depth and detailed research on the weaknesses of polyurethane elastomers such as aging and hydrolysis, and further improved the raw material formulation to produce higher quality polyurethane elastomers. The JHQ series buffer is made using this high-tech modified polyurethane material.

Features:
Performance comparison with other buffers:
If the elevator loses control and its speed exceeds the rated speed, its impact will increase exponentially. In this special situation, the spiral steel of the spring buffer will overlap or break, and the hydraulic buffer is prone to phenomena such as cylinder explosion, thereby losing its buffering effect and causing serious damage.
As a substitute for rubber buffers, our company's latest JHQ type polyurethane buffer for elevators can withstand impact forces several times higher than the EN81-1:1998 standard test data, ensuring maximum equipment and personal safety. This is determined by the physical structure and energy absorption principle of the product. It can exert the strong flexibility and elasticity of polymer chains, as well as the exhaust and energy resistance characteristics during product shrinkage. Polyurethane buffers, when subjected to impact, can make the car smoothly and smoothly descend without noise or vibration, making them a modern environmentally friendly product.
