Japanese Come-Along Clamps, also known as tension clamps or grip clamps, play a crucial role in overhead line installation and maintenance. Let’s explore them:

1. Purpose:

   • Come-Along Clamps are used to tension and secure overhead wires (such as contact wires or catenary wires) between masts or gantries.
   • They ensure proper alignment, tension, and stability of the wires.

2. Features:

   • Jaws: These clamps have jaws that grip the wire securely.
   • Tensioning Mechanism: The clamps can be tightened or released to adjust wire tension.
   • Insulated Handles: Some come-along clamps have insulated handles to protect workers from electrical shock.

3. Installation Steps:

   • Attach the clamp to the wire.
   • Use the tensioning mechanism to apply the desired tension.
   • Secure the clamp to the mast or gantry.
