Door Locking
The CMF door lock fully complies with point 11.5.1of UNI 10411-1/2 . The device prevents the cabin doors from being accidentally opened by the passengers, blocking the travel of the system and creating a gap between the cabin floor and the building floor.
In a manual system, doors are manually operated by the passenger and are monitored with contacts that signal the opening of the doors themselves, removing the operation of the system if they are opened with the lift in motion. When this occurs, the lift is blocked in whatever position it is in.
Recent safety regulations require that the car doors of a manual lift must remain closed and their unlocking is prevented until the lift has stopped normally because it has reached the floor perfectly. This is in order to avoid the possibility of a difference in level between the car floor and the building floor, which is a real possibility if the car doors are opened in the door unlocking area with the lift still not fully aligned to the floor.
As the regulations state that the door unlocking area is allowed to be 10 cm above and below the floor, in the above case a difference in height between the floor of the building and the floor of the car would be created, which could result in a stumble or fall for a possible subsequent passenger.
How does it work
The CMF door lock (A) consists of various leverages that control a metal plate (D). The metal hooks (F) must be applied on the outside of the car doors. The connection between the car door locking device (A) and the electromagnet for controlling the retractable skid (Z) consists of a metal cable inserted in a sheath (G) and two metal retainers (H).
The CMF door lock is directly actuated by the electromagnet – or the electric skid – to control the retractable skid via the flexible mechanical connection (G). This feature provides the certainty that, with the lift running, the locking plate is in the locked position making it impossible to open the doors. Conversely, with the lift stationary on the floor, the locking plate is in the retracted position, thus making it possible to open the doors.
The device is mounted outside the cab in the sill space, in an area not accessible to the passenger, thus preventing tampering.
In addition, the CMF door lock does not require any electrical connection.
