NEC Bend rule for secondary structure?

I had a job once in a high rise rewiring some new chillers. It was 2" pipe in the slab and can't remember what size the conductors were but they were THW and aluminum we couldn't pull them out, probably a 100 foot run. Based on the exposed elbows we could see they had more than 360 degrees even if they went like a crow flies and based on the wire size the pipe was overfilled. We ended up pulling them out with a comealong and had to constantly re-rig. The new wire was copper and smaller so they went in ok pulling by hand.
