I have pulled literaly 100's of miles of wire and cable over the years and really you are only limited by the size of your tugger and strength of your rope. The longest Ive been involved in was around 4000' at the UPS worldport Hub in Louisville Ky. Most in a tunnel on tray rollers into 6" conduit underground and up 80' to the roof. The tugger had a 460 Ford engine on it and the rope was a fiberglass core. when it moved an inch on one end it moved an inch on the other, No stretch at all. Which can be a killer on long pulls.
