Polyurethane Buffer For Elevator Bottom Buffer
Elevator polyurethane buffer is a kind of safety device used in
elevator system, which is usually installed at the bottom of
elevator shaft. It is made of polyurethane material and has the
characteristics of high elasticity and wear resistance. When the
elevator stops suddenly or suffers external impact during
operation, the buffer absorbs and disperses the impact force by
compressing polyurethane material, thus reducing the impact on the
elevator and passengers and ensuring its safe operation. In
addition, the polyurethane buffer also has a small size and weight,
which is convenient for installation and maintenance. In general,
elevator polyurethane buffer is an important part related to the
safety of passengers and elevators.
