Abstract

PURPOSE:To improve safety, workability and profitability by arranging large snatch blocks on both sides of a steel tower to be strung, engaging an electric wire with one large snatch block and a wire for wire extend with the other large snatch block and forming a wire extend loop. CONSTITUTION:When an electric wire 10 is extended between steel towers T1, T2 constructed on both banks at a distance L crossing a channel or a large river, large snatch blocks 1, 1' are disposed respectively at the rears of the steel towers T1, T2. The large snatch block 1 is installed at the rear of the position of approximately half the stringing length L of the electric wire 10 from a fixed shaft 7, the electric wire 10 is interlinked with a snatch block groove in the large snatch block 1, and the electric wire 10 is formed to a U shape. Temporary fixing clamps 5 are contact- bonded with both end sections of the electric wire 10, and connecting wires 7a and extending wires 11 are connected to connecting holes for the clamps 5. Both end sections of the extending wires 11 and the temporary fixing clamps 5 are coupled, and a wire extend loop is formed. The connection of the fixed shaft 7 and the electric wire 10 is released, and the wire extend loop is turned as shown in the arrow by using a wire extend winch 9 while the tension of the whole loop is varied by a block 3, thus extending the electric wire 10.
