Cable grips are woven sleeves that have an eye; they fit onto cables, forming an attachment point that can be used to secure or haul the cable. Cable grips automatically shrink onto cables when fitted over their ends. Grip increases according to the load that is placed upon it, ensuring that slippage does not occur. If you’re in the market for wire cable grips, you can learn more about them below.
How They Work:
As mentioned above, wire cable grips work by immediately “shrinking” when fitted over the end of cables. When shopping for a cable grip, it is essential to select one that will fit properly. As long as you choose a properly fitted cable grip – and use it correctly – you won’t have to worry about it inadvertently slipping. Additionally, buying a cable grip from a professional and reliable manufacturing company who has respect within the industry is going to be of value when it comes to quality.
Types of Grips:
There are several different types of grips that you can buy in New Zealand. The most common kind is the tubular grip. These grips come in a cylindrical shape and are available in 1- to 5-ply constructions, depending on the amount of strength that is needed. Three different eye styles are also available. Tubular cable grips fit over the end of cables; styles include:
Open Tubular Double Eye: In the circumstance where cable is needed to be laid out and attached to walls, the open-tubular-double-eye grips are the most suitable option.
Open Tubular Offset Eye: Open tubular offset eye cable grips are optimal for pulling slack during the last placement of cable in exchange buildings; They can also be utilised for tightening slack while the final placement of cabling at termination points such as pole tops, where it isn’t a possibility to haul the end from the cable.
Closed Tubular Single Eye: The closed-tubular-single-eye cable grip is able to be used within trenches, conduits (underground), service lines going into industrial factories and cabling-trays. They are suitable for the light to medium hauling of power and communication cable as well.
Basic tips for using cable grips include:
> Choose the right grip for the job.
> Store grips in dry places.
> Prepare cable ends properly, by chamfering them to about 30 degrees, or a distance that’s about half the diameter.
> Inspect grips before and after every pull.
> Use banding. It should be placed about 30mm from the mouth end of the grip to lessen the risk of slippage. Securely taping down the mouth end of the grip is also a good idea.
> Never use damaged grips.
> Don’t haul grips over abrasive surfaces, or inspect them regularly if you do.
> Don’t use CLP wire grips for lifting.
Cable Laying companies manufacture a range of hand woven wire cable grips which are designed for hauling power, telecommunication data, fibre optic and coaxial cables and for winching rope through conduits, trenches and overhead poles. High quality galvanized steel wire is used in weaving the individual grips – stainless steel is available on request. The weaving process should leave no loose or frayed wires at the tail end to cause damage to the cable or the conduit. The length of grips should also be customised for customer’s individual requirements.
If you’re using Wire Cable Grips for the first time, it can be very confusing. There are several different types available, and knowing which one is right for you isn’t necessarily intuitive. Available in Australia and New Zealand; see Cable Laying Products.
