Cable Grips - Selection, Inspection and Application

As well as designing, developing and distributing great products, TEN Group also support customers with detailed and useful guides.

This latest guide is for cable grips and offers sound advice on the selection of the correct grip, the inspection with areas of concern and a step by step guide on how to use a cable grip effectively and safely.

 

This is a guide for the Selection, Inspection and Application of cable grips to ensure the safe pulling operation, optimum grip strength and grip longevity

The grips are safety critical and must be used by competent trained personnel.
It’s essential to choose the correct grip for the job.
There are a number of variables that can weaken a cable grip that are not immediately obvious on visual inspection, this is why a Safety Factor is used.
It’s important to know the difference between Working Load and Approximate Break Load, and how to use the Safety Factor to calculate the Working Load Limit for the cable grip that will be used.
The Working Load Limit (WLL) is calculated by dividing the Approximate Break Load by the Safety Factor.
The Safety Factor is determined by existing company, local utility or industry safety guidelines.
NOTE: To ensure maximise grip performance, the grip must be double banded, as described in the “Application Instructions” - downloadable below.
There are many factors that must be taken into account when assessing the suitability of a cable grip for a proposed application and calculating the WLL.
These include:
• Size of cable grip in relation to size of the Cable/Conductor
• Approximate breaking strength of the cable grip.
• Suitability and compatibility of any attachments used - Swivels, Rope, etc.
• Stability of object(s) when gripped.
• Grip surface of conductor.
• Resistive force of conductor.
• Anticipated path of movement:
Underground - through conduit, number of bends, use of cable lubrcant.
Overhead - through rollers, number of rollers, diversions/angles.
• Environment/operating conditions.
• Condition of cable grip.
If you have any questions regarding suitability for any particular grip application, please contact TEN
Please note: Cable grips must be double steel banded securely before being pulled.
