Is it necessary to replace the limiter?

[DeZane]

It is necessary to replace the limiter. The introduction and principle of the limiter are as follows: Introduction to the limiter: The safety limiter, also known as an overload limiter, is a safety device designed to protect machinery and its users, commonly found in automobiles and cranes. Principle of the limiter: During the door opening and closing process, the slider inside the limiter cover moves back and forth on the main arm. Since the thickness of the main arm varies along the direction of movement, the displacement distance of the slider differs, and the force exerted on the rubber block also varies. As a result, different door opening and closing forces are generated during the process, achieving the limiting effect.
