What is a relating device?

A relating device is specifically designed to connect and determine the speed of two or more door panels of an elevator system. This ensures that the door panels operate in synchronization, allowing them to open and close smoothly as one unit, which is crucial for both the safety and functionality of the elevator. By coordinating the movement and speed of the door panels, the relating device helps to prevent situations where one door could operate more quickly than the other, potentially leading to malfunctions or unsafe conditions.

In the context of elevator systems, having such devices is important for maintaining proper operation and ensuring that passenger doors open and close without hesitation or delay. This contributes not only to the efficiency of the elevator but also to passenger safety as it helps avoid the risk of injury from improperly functioning doors.
