The benefits of locking the manhole mainly include the following aspects: Safety: Locking the manhole can effectively prevent unauthorized personnel from entering the manhole and ensure that only authorized personnel can open it, thus ensuring the safety of the place.
Especially in some places that need high security control, such as machine room and elevator shaft, the locked manhole can prevent illegal intrusion and avoid potential security risks. Convenience: The design of the locked access door makes the maintenance and overhaul more convenient.
The staff can easily unlock the door lock through a special key or operation password, and enter the access door for necessary maintenance and inspection. This not only improves the working efficiency, but also reduces the loss caused by frequent switching.
