A mechanical dynamometer capable of measuring up to 20,000 lbs. The direct method uses mechanical or hydraulic equipment to pull the guy wire to measure the tension with a calibrated gauge. Direct and indirect are the two common methods of measuring guy tension on towers. Initial tension may be mesured by vibration frequency, mechanical tensionmeters, measurement of guy sag, or by other suitable methods. The installed tension for guy wire is typically 10% of the wire’s breaking strength. Preform Grips - Cable Clamps - Thimbles - Dead End SleevesĪligning yourself with the right tensioning tools Additional information can be found in EIA/TIA 222F. Check construction drawings for site specific initial tension requirements.
*Typical pretensioning is 10% of the breaking strength. We recommend that you contact our valued distributors for your site-specific guy wire and attachment hardware requirements. Use the guy wire calculation program to quickly identify the total length of guy wire that the project will require.
To allow for sag and tensioning, 5 to 10% should be added to your guy wire lengths. The following average distributor pricing for EHS galvanized steel guy wire, preformed grips, cable clamps, thimbles, dead end sleeves and turnbuckles does not include taxes or freight.
