How to operate the safety switch of elevator car roof guardrail

The safety switch of elevator car roof guardrail is a safety device, which is used to monitor whether the car roof guardrail is closed. When the elevator car closes the guardrail, the guardrail safety switch is triggered to ensure the normal operation of the elevator. The action process is as follows:

1. Guardrail closing: When the guardrail of the elevator car is closed, the safety switch above the guardrail is in the trigger position.

2. Trigger process: When the guardrail is closed, the guardrail contacts the safety switch to move the trigger device from the trigger position to the safe position.

3. Safe position: Once the trigger device moves to a safe position, it means that the guardrail has been closed correctly and the elevator can start running.

4. guardrail opening: when the guardrail of the elevator car is opened, the trigger device moves back to the trigger position. If the elevator tries to run or close the gate, the safety switch will immediately trigger to stop the elevator to ensure the safety of passengers.

It should be noted that the specific action process of the safety switch of the elevator car roof guardrail may be different for different elevator types and manufacturers. Therefore, please follow the manufacturer's instructions and standard operating procedures in the specific elevator installation and maintenance process. If you have more detailed requirements for the safety switch action of a specific elevator model, it is recommended to consult a professional elevator manufacturer or maintenance personnel.
