The use of steel belt transmission in elevators is a new technology that has been introduced recently, which can effectively reduce vibration and noise. However, the steel belt manufacturing technology in my country is not up to standard and is basically imported. Currently, some manufacturers that use steel belts include Tianjin Otis, Schindler, ThyssenKrupp, Hitachi and other first-line manufacturers. Other manufacturers have not yet used it in large quantities.
