To uniformize the tension of a large number of strands when tension is introduced into a cable formed by binding up strands.
After set tension is introduced into a master strand and the master strand is temporarily fixed, to tense the second strand and subsequent, the tension of the master strand at that time is measured, and the tension equal to the measured value is set as tension for introducing into each strand. Then, the set tension is introduced in order into each strand. After the step is repeated in order, and the last strand is fixed, the master strand is fixed. When the tension introduced into the master stand is set, a temperature compensation is performed. When the tension introduced into the second strand or subsequent is set, a compensation is performed with the weight of each strand and a set loss taken into account. The tension is introduced into the cable using two steps comprising a primary tense step and a secondary tense step. At least the primary tense step is performed.
