Apprentice path · Stage 18: Raceways · Lesson 63

Planning a conductor pull

A pull is planned before anyone touches the rope: the route, who is where, how they talk to each other, and what force is allowed.

Why this matters on the job

A pull goes wrong quickly and expensively. People are at both ends of a run they cannot see along, and the person pulling cannot see what the person feeding is seeing.

How to think about it

  1. Plan the route, the access and the communication before starting.
  2. Use suitable equipment and approved pulling methods.
  3. Respect the manufacturer's tension and bend limits.

Worked through

Communication is the part that is not about equipment. Both ends have to be able to stop the pull, and that only works if it was agreed before anyone started. The default without a plan is that the person at the winch keeps going because nothing has told them not to, while the person at the reel is watching something go wrong.

Check yourself: The pull suddenly gets harder. Do you put more force on it?

Answer: No. Stop when unexpected resistance appears; do not simply pull harder.

Unexpected resistance means something changed that you did not plan for -- a snag, a bind, a bend doing more than it should. Adding force applies that force to whatever the problem is, which is usually the conductor.

Watch out for: Treating tension limits as advisory. They come from the manufacturer for that cable, and exceeding them damages conductor and insulation without necessarily stopping the pull.
