摘要： PROBLEM TO BE SOLVED: To provide a method for replacing the support bolt of an insulator string in a short time without removing the wires and without stopping power supply for a long time, while reducing the man-hours and expenses.SOLUTION: Two suspension yokes are fixed to the opposite side edges of a line side yoke and supported by means of a semi-wire 45 connected to a winch. A Lever Block (R) 47 is fixed, at one end thereof, to an arm metal 31, and at the other end thereof, to an insulator hanger 4. A triple insulator string 39 is latched to the lower end of the insulator hanger 4 by means of a latching tool 5, and the load acting on a balance yoke 38 is released by operating the Lever Block (R) 47 to support the insulator hanger 4. A Lever Block (R) 48 is fixed at one end thereof to the arm metal 31, and at the other end thereof, is connected to a ground-side yoke 35. The load acting on a cotter bolt 36 is then released by operating the Lever Block (R) 48, to support the ground-side yoke 35, and the cotter bolt 36 is replaced.
