Abstract (en)
[origin: JPH01133879A] PURPOSE: To prevent the overload by inhibiting the responding to the assigned call in a first circuit in a case where the overload of a car is expected when the car is stopped at the respective floor, and responding to the assigned call for the non-serviceable floor in the going way, by a second circuit. CONSTITUTION: A first and second circuits 14, 15 connected with a control device 5 are activated every position of a selector for making a car respond to the assigned call from a call registering device 8 of the respective floor through a multiplexor 10. On this occasion, when the load in the car 2 detected by a load measuring device 7 is expected to be overload when the car is stopped at the respective floor on the basis of the load memory 13, the first circuit 13 is inhibited from reponding to an assigned call. The second circuit 15 inhibits the scanning of a selector relating to a call in the opposite direction, so that the car travels without stopping back to the non-serviceable floor to respond to the call input from the call registering device 8 on this floor, whereby the overload at the stop at the respective floor can be prevented.
