What happens during the compression stroke of buffers in type C safeties?

During the compression stroke of buffers in type C safeties, a retarding force is developed. This mechanism is crucial for safety systems in elevators, as it helps to absorb and dissipate kinetic energy during the event of an elevator overspeed or uncontrolled downward movement.

As the buffers compress, they respond to the force exerted by the descending elevator car. The design of type C buffers allows them to generate a significant retarding force, which effectively slows down and ultimately stops the elevator car before it can cause damage or injury. This force is essential to ensure that the elevator system operates within safe limits and prevents potential accidents.

It’s important to understand that during this process, the force generated is directly proportional to the compression of the buffers, which means that the greater the descent or impact, the more force the buffers exert to decelerate the elevator car. This function distinguishes type C safeties as an integral part of elevator safety systems, providing a reliable means to protect passengers and equipment during emergency situations.
