 11. The elevator system of claim 10, characterized in that said fourth switching means operate in a closed state when the specified door on the floor approaches a closed position, but still at a certain distance from it, and after said third switching means the chains have already worked and the cab door is in the closed position.
 12. The elevator system according to claim 11, characterized in that said safety circuit unit comprises sixth switching means connected to said fourth and second circuit closing means to prevent said cabin from moving until the fourth circuit closing means is in a closed state .
 13. The elevator system according to claim 1, characterized in that said first means of closing the circuit act in a closed state when the cabin door approaches a closed position, but still at a certain distance from it, and said second means of closing the circuit act in a closed state when the cabin door is fully closed, and after said first circuit closing means are already closed, said second switching means comprise third circuit closing means e in the closed state in accordance with the position of the cab door and until the first said circuit closure means come into a closed state, and the third switching means connected to said first circuit closure means and preventing said cabin from moving until said first circuit closure means will be in a closed state, wherein said safety circuit unit comprises fourth switching means connected to said second circuit closing means to prevent the movement of the cab until these third circuit closures are in the closed state.
 14. The elevator system according to item 13, wherein it further comprises fifth switching means connected to said second circuit closing means to prevent said cabin from moving until said third circuit closing means are in a closed state.
