Elevator Safety Clamp Gear with 0.63-2.5m/s Speed Range and 750-12500kg Capacity for Lift Systems
Elevator instantaneous safety clamp, also known as elevator speed protector, is a critical safety device used in elevator systems. This device continuously monitors elevator running speed and activates immediately when speed exceeds preset safety limits, ensuring safe elevator stopping and preventing dangerous situations.
Instantaneous safety gear systems consist of speed sensors and emergency braking devices. Speed sensors installed in elevator shafts or machine rooms monitor elevator velocity. When speed exceeds safety thresholds, sensors trigger emergency braking mechanisms that apply immediate stopping force.
