Compared with the instantaneous safety gear, the progressive safety gear has better buffering performance. When the elevator fails or goes down over speed, the impact load it generates is smaller, and it is generally used for non-low speed elevators. It is very good to ensure the safety of people and goods.
The elevator safety gear produced by our company adopts the Π-shaped spring structure clamp body as an elastic element. When working, the jaw is a fixed wedge on one side, and a movable wedge on the other side to pull the safety gear. Through the connection between the wedge and the guide rail The contact between them creates friction and eventually clamps the guide rails to stop the car and keep it stationary.
SGA1 series, our company currently has four models A, B, C, D, which can meet your different tonnage needs.
