What is a wire puller used for?

When running cables indoors, you may need to use a cable puller tool. Some cables span over 100 feet. Running cables long distances such as this may require the use of a cable puller tool. It will allow you to easily pull the cables through narrow or otherwise small conduits that you can&#;t access by hand.

What Is a Cable Puller Tool?

A cable puller tool is a handheld tool that&#;s designed to pull cables through a conduit. If you can&#;t access a conduit by hand &#; or you can&#;t extend your hand all the way through the conduit &#; you may struggle to run a cable through it. A cable puller tool offers a solution. As the name suggests, it will pull the cable through the conduit.

Benefits of using a cable puller tool include:

• Ability to run cables through narrow conduits
• Faster cable installations
• Preserves and protects cables from damage during installation

How to Use a Cable Puller Tool

You can use a cable puller tool to run cables through hard-to-reach conduits. While they are all designed to pull cables through conduits, though, they are available in different types.

Some cable puller tools feature a capstan. They are electrically powered. When turned on, these capstan-based cable puller tools will rotate. As it rotates, it will pull both the cable and a rope through the conduit.

Other types of cable puller tools feature a long and rigid rod. You can tie the cable to the rod, after which you can push the rod through the conduit. You can then untie the cable from the rod. Rod-based cable puller tools such as this are the simplest and least inexpensive. When compared to capstan-based cable puller tools, though, they are most laborious. You can use a rod-based cable puller tool when running cables short distances. But for long distances, you may want to choose an alternative type of cable puller tool.

There are also cable puller tools that leverage a vacuum. Known as conduit mouse pullers, they feature a piston. You can place a cable in the piston, after which you can place the piston in the conduit. Connecting a vacuum to the end of the conduit will pull the piston, as well as the included cable, through it.

In Conclusion

Cable puller tools are designed to pull cables through conduits. Some of them use a rod. Other cable puller tools use a capstan or vacuum.

Pulling electrical cable through conduit is a labor-intensive task. Prior to the availability of electricity-powered cable pullers, this task was always performed by hand.

Cable pullers can save you money on labor costs and improve safety. Since you&#;re not pulling by hand, your body will experience less strain and you can devote your attention to watching for problems.

This article will take a closer look at the main kinds of equipment used by electrical workers for wire handling.

How does a cable puller work?

The cable puller makes use of a power source that fuels a turning capstan. The capstan pulls the wire and a special kind of pulling rope through the conduit, replacing the need to pull it manually.

Cable pullers come in different sizes and are often portable. They can handle various pulling forces, with some models able to take on around 10,000 pounds. Some cable pullers also have force gauges that help you notice problems faster.

Using a manual fish tape as a cable puller

Feeding tape through a conduit is a necessary first step before using a cable puller. Fish tape is used primarily on smaller projects and is often the preferred method for pulling wire through conduits.

Fish tapes are steel, stainless steel or fiberglass wire that&#;s stored in a wheel-shaped plastic structure, and the way the fish tape is stored makes it easier to feed into the conduit.

For steel fish tape, one worker holds the fish tape holder (the doughnut-shaped wheel) and the tape is hand-fed into the conduit. Once it emerges on the other side, the electrical wires that need to be fed through the conduit are attached to the fish tape, which allows the wires themselves to be pulled through the conduit with ease. Both the tape and wires are fed into the conduit and manually pulled back to where the fish tape was originally fed into the conduit, completing the process.

For fiberglass fish tape, you must hook onto fish line and pull that back to hook to the cable. Fiberglass fish tapes are not designed to directly pull the wires due to their fragile nature.

Pulling rope for cable pullers

Cable pullers use a special pulling rope that must be incredibly strong and able to handle friction. It&#;s important to know the tension capabilities of pulling rope, as well as how friction affects rope when it&#;s used on a capstan and how much it will stretch.

Choosing the right rope size is also crucial. Even if you determine that your pull won&#;t exceed 2,000 pounds, for example, you don&#;t want to use a ½ inch diameter rope with a 10,000-pound cable puller. If something catches and the rope breaks because it wasn&#;t rated for the pressure of the machine, it could cause injury. Read your cable puller&#;s specs to identify the correct rope size.

A rope that stretches is not acceptable because like a stretched rubber band, it will be released if the rope snaps. This could cause the cable to recoil and injure someone.

Double-braided composite rope is the best choice for pulling because it&#;s like two ropes in one. It&#;s also a high-strength, low-stretch rope.
