For the selection and installation of instantaneous safety gear, attention should be paid to elevator parameter matching:
Rated speed: The applicable speed range of the instantaneous safety gear should match the rated speed of the elevator. If the speed parameter of the safety gear is lower than the elevator running speed, it may not be able to brake in time in an emergency, leading to danger. Conversely, if the safety gear speed parameter is too high, it may cause false actions during normal operation and affect the elevator's usage efficiency.
Load capacity: Select safety gear of appropriate specifications according to the elevator's load capacity. Elevators with different load capacities generate different impact forces during braking. The safety gear needs to have sufficient strength and braking force to deal with the corresponding load. For example, elevators with a large load capacity need to select safety gear with stronger bearing capacity.
Car size: The size and installation position of the safety gear should be suitable for the size of the elevator car. Ensure that the safety gear will not interfere with the car structure after installation and can effectively clamp the guide rail to achieve reliable braking.
Guide rail matching: The safety gear should be installed on the guide rails on both sides of the elevator car to ensure the matching accuracy with the guide rails. The installation position should be accurate. So that the braking elements of the safety gear can be in close contact with the guide rails in an emergency to achieve effective braking. During the installation process, professional measuring tools and installation equipment are needed to ensure that the parameters such as parallelism and perpendicularity between the safety gear and the guide rails meet the requirements.
