ABSTRACT:
An operating system placed on the cabin door is shown with a continuous line in rest position and with a dotted line in working position. An arrow marked with a (Y) indicates a horizontal movement undertaken by the operating system in the Y-direction and an arrow marked by (X) indicates a horizontal movement undertaken by the operating system in the X-direction. The X/Y movement of the operating system is produced by an actuator and motive mechanics. On a shaft door is placed an operating cam upon which the operating system rests. Operating system sensors measure the distance to the shaft door and the operating cam. An electromagnet of the operating system produces the necessary force for coupling of cabin door to shaft door.
