Aligning yourself with the right tensioning tools

The installed tension for guy wire is typically 10% of the wire’s breaking strength. Initial tension may be mesured by vibration frequency, mechanical tensionmeters, measurement of guy sag, or by other suitable methods. Direct and indirect are the two common methods of measuring guy tension on towers. The direct method uses mechanical or hydraulic equipment to pull the guy wire to measure the tension with a calibrated gauge. A mechanical dynamometer capable of measuring up to 20,000 lbs. runs approximately $900.00 list. The indirect method uses assumptions and calculations to predict the tension. The most common application of this method is the Sag Intercept method. Another tool measures the harmonic frequency of the guy wires and runs $2,900.00 list for measuring the tension of wires up to 3/4”.

Cycling method sometimes used

Although not as reliable as other methods, an oscillation technique can be used to identify the approximate tension when all of your testing equipment is on another job site.

Grasp the guy wire in front of the anchor and start a horizontal pendulum-like motion by pushing from side to side. When the guy is swinging slightly and easily in a side-to-side single arc, begin to count as it hits your raised index finger. Push lightly on the guy to maintain the motion while counting. The below chart will indicate how many cycles per minute there should be for the accompanying guy wire length of all sizes.

Ambient temperature affects tower guy tensions and must be considered when adjustments are made. There should be relatively little wind when taking the measurements. Check construction drawings for site-specific initial tension requirements.

The direct method using a dynometer

A dynomometer with a length adjustment device, such as a come-along, is attached to the guy system by clamping onto the guy justGuy Wire 2 above the turnbuckle and onto the anchor shaft below the turnbuckle.

The come-along is then tightened until the original turnbuckle begins to slacken, allowing the dynometer to carry the guy load to the anchor. The guy tension is then read off the dynometer dial.

By adjusting the come-along the proper installation tension will be attained when registered on the dynamometer.

Two registration points are then marked, one above the clamping point on the guy wire and one on the anchor shaft, and the control length is measured. The dynamometer and come-along are then removed, and the turnbuckle is adjusted to maintain the registration points measured.
