Cable pulling grips allow contractors to transport cables from point A to point B without damage. They allow users to hold onto the cables through the installation or removal process by stringing or conduit.
Grip should be secured by contractors in determining the peculiarities and type of application of the cable run. The following are questions one might consider to answer before installation:
- If you pull through the conduit, do you see many bends?
- Are you going to run the cables indoors or outdoors?
- What are you trying to pull: copper cable or fiber-optic cable?
- What is the breaking strength of the grip?
Before installation it is critical to ensure that the grip is firm enough for the job. If the grip is too weak, the able could pop off and interrupt the pull.
Variety of Grips
There are several types of cable pulling grips. The objective of such is the same – however, each type offers a different way to pull the cable:
- Set-screw: this grip can pull up to four cables through its locking heads. It offers flexibility when it comes to the size of the wire you are going to pull. Hence, it is used for long pulls such as bulky copper cables.
- Wire-mesh: This grip offers a different gripping action and depends more on the mechanical gripping points. Unlike the set-screw that relies on two or more points, the wire-mesh grip is known for its steady pull. It is often used for an outside-plant application such as overhead utility lines. The design of wire-mesh (that being either single or multi-weave) can also be established by the size of the cables being pulled – as the size determines how much force is used by the pull.
The best cable pulling grip is dependent on the task and scope of the project at hand. Deciphering the needs of the task will favour one pulling action over the other.
