![]() One man pulls are possible with really good setups but two is normally a minimum. ![]() BUT you can get by with less if again you spend more time on setup to eliminate any snags, rollers or slides to guide everything in…everything you can to make a successful pull. The man runnjng the puller and the one guiding it in have hands free cell phones or radios or can yell signals. One to run the puller and one to guide it back out. If you spend a lot of time setting up your pull then it will go much easier. This is “fast” but leaves twists in the cable that just turn from twists to kinks. Do NOT pull sideways off the side of a spool ever. When you pull off cable to lay out all spools must go in the same direction. Either lay out every cable first and tape them together as suggested or I just set up enough spools on a rack. Two electricians are going to top out at maybe 300 pounds. So a cheap Pullzall that you can find in just about any industrial supply is plenty. Realistically #14 is only good to around 100” pounds tension before you rip the jacket off or pull the copper apart. If the app says it won’t work then lesson learned on that water line you just put in. Verify how much tension you need to even make this pull possible, if at all. Ok first download the Greenlee PullCalc app or something similar. Is there any other methods that you can possibly share and help us? Thank you for reading. I suggested running all of our mule tape lines at once, and having them all straight and in there and having them secured on both ends, but was shot down by the forman. We rigged pulleys at the end of the conduit on beam clamps to try to re-direct and get better angles to pull. We are keeping tension on the mule tape as it goes in. The reels are so large we cannot possibly run more than 3 at a time. We are pulling one line at a time, and running mule tape with each pull. Im getting to the point where we have exhausted all options of making things go smoother. The pulls still are near impossible (2 of our largest men with their entire body weight and strength pulling) and to top it all off the jacket on the wires is extremely fragile, so im pretty sure everything in the conduit is FUBAR at this point, but only time will tell. We’ve already re-rodded the conduit multiple times between pulls with a tennis ball on the end (high tech i know). Long story short, after 8 lines in there our mule tape is certainly getting more and more wrapped. Not only are there multiple back to back 45 sweeps, but some of the bends dive and rise and some sweep side to side. We are running into a lot of trouble pulling through a particular run of 250ft, with a ton of bends, at LEAST 360 degrees. The cables are, if i remember 8-pair 14AWG, roughly the size of 00 wire in total. ![]() We are currently pulling a LOT of lines through 4” conduit in a stadium for Voltserver digital electricity. I’m seeking advice on pulling multiple lines through large conduit runs.
