The SGA2A safety gear is the same as the SGA2 safety gear. The elastic elements are the same disc springs. Their working principles are the same. . During use, it is clamped on the guide rail by elastic clamping force and slides, and the kinetic energy and potential energy of the car are consumed by the friction with the guide rail, so that the car is stopped.
The difference is that their allowable quality is different when they are used. When purchasing, you can compare and choose the appropriate product according to the actual situation.
