What tools are needed to pull a cable in a conduit with multiple bends?
2025-08-16A conduit with multiple bends increases the total pulling tension, requiring specialized tools to get the job done. The essential tools and equipment include:
-
A Hydraulic Winch with a Tensiometer: This is the most crucial tool. The winch provides the necessary pulling force, and the integrated tensiometer allows the operator to monitor the pulling force in real-time. This ensures the tension stays below the cable's maximum limit, especially as it navigates each bend.
-
Cable pulling grip (or Sock): A wire mesh pulling grip securely attaches the pulling rope to the cable. For runs with multiple bends, a rotating Swivel should be used with the grip to prevent the pulling rope from twisting and kinking the cable.
-
Conduit Pulling Rope: A low-stretch, high-strength rope made of materials like polyester or aramid fiber is used to connect the winch to the pulling grip.
-
Conduit Rollers and Sheaves: These are placed at each bend or curve to guide the cable smoothly and prevent it from dragging along the conduit wall, which would dramatically increase friction.
Using the right tools for a job with multiple bends is not just about efficiency; it's about safeguarding the integrity of the cable and the safety of the crew.
