Product name: safety gear
Product Category: Progressive Safety Gear
Elastomeric element: U-spring structure safety gear
Conditions of use: 1. If the rated speed of the elevator is greater than 0.63m/s, the car should adopt a progressive safety gear device. If the rated speed of the elevator is less than or equal to 0.63m/s, the car can adopt the instantaneous safety gear device.
2. If the car has several sets of safety gear devices, they should all be progressive.
3. If the rated speed is greater than 1.0m/s, the counterweight safety gear device should be progressive, and in other cases, it can be instantaneous.
The progressive safety gear has good cushioning performance, small impact load generated by braking, less adverse impact on the structure and transmission system, and less physical and psychological impact on the occupants, which can well ensure the safety of personnel and goods. Therefore, Non-low speed elevators must be fitted with progressive safety gear.
