The arithmetic and control unit generates a signal for controlling the supply of the pressure oil to the hydraulic jack 13 when the hydraulic jack 13 is turned on.

When the difference in the elongation dimension of the main rope 9 exceeds the allowable dimension (for example, several millimeters), the arithmetic and control unit 19 changes the effective rope length effective means engaged with the main rope 9 whose elongation dimension exceeds the allowable dimension. A control signal for supplying pressure oil to the hydraulic jack 13 is generated and sent to the pressure source 17 so that the plunger of the hydraulic jack 13 expands (retreats in the case of the hydraulic jack 13A). Push in the main rope 9 only.
【００１５】これにより、その主ロープ９は押し込まれ
た分だけ有効長さが短くなり、伸び寸法が吸収され、補
正される。As a result, the effective length of the main rope 9 is reduced by the amount of being pushed in, and the elongation dimension is absorbed and corrected.
