Description: The Elevator Parts Safety Gear is a paramount safety feature tailored for elevators, expertly engineered to prevent accidents. This state-of-the-art progressive safety gear activates during overspeed incidents or suspension device failures, halting the elevator car or counterweight on the guide rail. The safety block ensures the elevator car remains stationary, providing unwavering passenger safety. Adhering to the highest safety standards, this vital elevator component is robust and reliable, guaranteeing smooth and secure elevator operation.
The Safety Gear is an essential mechanical device crafted to immobilize a car or counterweight on the guide rail during overspeed situations or suspension device malfunctions. Safety tongs are critical protection devices, forming one of the most crucial safety components in elevators.
These essential components, including safety gear, speed limiters, and landing door lock devices, are integral to the safety functions of elevators. They must undergo rigorous type-testing certification to ensure their effectiveness and reliability.
Typically, safety tongs must engage in a downward motion, stopping the car or counterweight carrying the rated load when the speed limit is reached. They clamp securely onto the guide rail to hold the car or counterweight in place during suspension device failures.
Meticulously engineered, the elevator safety clamp device stops the elevator car in emergencies, guided by the speed limiter. It clamps the car onto the guide rail if the elevator speed exceeds the set limit or rated speed, or if the suspension rope breaks or slackens. This device is vital for the elevator's safe operation and is usually installed on the car frame or counterweight frame.
Safety tongs come in two types: instantaneous and progressive. Instantaneous safety tongs are designed for elevators with speeds ≤ 0.63m/s, providing rapid action on the guide rail to brake and decelerate instantly. In contrast, progressive safety tongs are intended for speeds >0.63m/s, offering a gradual braking and deceleration process to regulate force on the car or counterweight within specified standards.
