The crew was setting a new pole. When pulling on the guy wire to transfer it to the new pole, the anchor broke and pulled out of the ground. The anchor had apparently penciled and grown weak over time. When the anchor gave way, the old pole swung toward the new pole. No equipment was damaged and no employees were hurt. It appears the anchor rod penciled over time and grew weak. When the crew pulled on the guy wire to transfer it to the new pole, it broke just beneath the surface of the ground. In order to prevent a recurrence, it is recommend that crews dig a few inches below the surface of the ground around each anchor rod to inspect for signs of decay prior to changing strain.
