Pull Tension

Pull Tension takes the cable, conduit, lubricant and the run in the order the cable meets it, and gives back the pulling tension, the sidewall pressure on each bend, the jamming check, the pull direction, the puller size and a pull plan.

The drawing

The run drawn isometric to scale, each bend colored by its sidewall pressure against the limit, with the tension along the run in the direction it is pulled.

Drawing the program wrote: Three 4/0 copper and a 6 AWG ground in 2 in RMC, pulled from the far end. All three bends are green, under 80% of the 500 lb/ft limit, the worst at 306 lb/ft (61%); the tension peaks at 347 lb out of the last bend and ends at 279 lb over 154 ft.

The example, step by step

The phone app's example job, Example - reference pull, opened with Open phone job… and worked out by the Suite.

  1. Pull Tension in Stinger Pro: The example in, before it is worked out: three 4/0 copper and a 6 AWG ground in 2 in RMC, Polywater J, and a six-step run with three 90s at 9.5 in.

  2. Pull Tension in Stinger Pro: Worked out: pulled from the other end. The pull plan: 2.252 lb/ft bundle, weight correction 1.400, mu 0.20, 500 lb/ft sidewall limit, jamming ratio 3.32, other way 328 lb.

  3. Pull Tension in Stinger Pro: The run isometric from behind the reel, each bend with its sidewall pressure: B1 306 lb/ft (61%), B2 148 lb/ft, B3 95 lb/ft.
