To continue from the previous posting, here’s some more suggestions for cable pulling. We’ve already reviewed cable tension and how to manage that<\/a>. This time, I’ll cover the remainder of the hardware that can be applied to a successful pull. Starting at the beginning and progressing through the length of the pull:
\n– Duct Rodders<\/a> are available in a range of sizes to suit the job, and are the simplest way to push or pull the initial messenger lines through the ducts.
\n 
\n
\n– Duct-Checkers<\/a> can be then pulled to ensure the bore is clear, and synthetic pull tape<\/a> or line can be pulled through with the trailing eye.
\n– Attaching a pulling eye to the cable can be done with Pulling Grips<\/a> or with DCD\u2019s Power-Grip Pulling Eyes<\/a>. Pulling Grips are very common, but you must make allowance for Safety Factors between the pulling force and the breaking strength. DCD\u2019s Power-Grips are re-useable end fittings that are stronger than the cable, and they limit damage to the cable to a very short end section.
\n– A Line Swivel<\/a> should be linked between the pulling cable and the cable\u2019s pulling eye to eliminate twist in the electrical cable. Eliminating this torque also contributes to reduced pulling force. Always choose a Line Swivel with excess capacity.
\n– At the cable reel end, a Duct Entry Guide<\/a> provides a durable roller at the duct entry. DCD Guides are provided with a standard spray nozzle for connecting to a Lubricant Applicator<\/a> to provide continuous cable lubrication.
\n– Exiting the duct at the pulling end, DCD Quadrants<\/a> have large aluminum rollers to maximize corner radius and distribute point loads on the cable. Alternatively, the range of DCD Hanger Sheaves<\/a> offers a range of sheave radii to suit the cable manufacturers\u2019 design allowables.
\n– An Offset-Eye Pulling Grip<\/a> can be laced onto the mid-span of the cable for short, repetitive pulls to draw extra cable at the pulling end.
\n– Finally, the Tuf-Lugger<\/a> does the heavy lifting \u2013 as described before.
\nIndividually, each offers some small advantage when pulling cable. And altogether, you’ve got a pretty good team!<\/p>\n","protected":false},"excerpt":{"rendered":"
