きないという問題点がある。 In twin/simple catenary sections where two overhead contact lines are installed on one overhead contact line, the overhead contact line is moved up and down to match the slope of the overhead contact line to prevent the pantograph from hitting the overhead contact line. Suspensions are carried out at different heights. To do this, a pair of suspension wires that suspend the overhead contact line must also be installed so that they are tilted at a predetermined angle with respect to the horizontal, in accordance with the inclination of the contact line.
2. Description of the Related Art Conventionally, there is a support metal fitting as shown in FIGS. 4 and 5, which suspends a pair of suspension wires at a desired angle of inclination.
This is attached to the lower part of the support pipe P ₁ that extends above the electric train tracks at right angles thereto, and the center of the hook 12 is rotatably attached to the hanging fitting 11. Hook 1
A suspension wire M is hung at both ends of the wire. However, this overhead wire support fitting has support pipe P ₁ ,
It is installed surrounded by support rods such as a steadying pipe P ₂ and dropper rods P ₃ and P ₄ . For this reason, there is a problem in that the support rods become an obstacle and it is impossible to carry out overhead line work using a dedicated overhead line car.
