Zusammenfassung:	PURPOSE:To provide a method of tension-controlled cable laying, in which the increase in tension of a large-diameter object passing through a support can be prevented effectively without any special means provided on the support itself. CONSTITUTION:A spring 3 (length-regulating means) is caused to lie in a suspension cord 2 for suspending a support 1 from the arm A of a steel tower or utility pole and stretched by a load applied to the support according to the increase in tension occurring at the time of the passage of a large-diameter object so that the suspension length L of the support 1 is adjusted automatically and the factors of the tension rise are solved accordingly.
