Abstract
A device for rotating, setting and locking driven pivotal ground anchors and for applying a predetermined tension to test load the locked anchor, comprises a horizontal base plate having an opening through which an anchor rod or cable can project, an upright post extending from the base terminating in a moveable arm carried by the post, which can be attached to the anchor cable through an intermediary cable, chain, or other fastener. The arm is rotatable through a socket drive rotatably carried at the top of the post, which can be actuated by a hand or power torsion wrench to cause rotation of the arm, to draw the anchor up, to rotate it in the ground to its set position and to apply a predetermined tension determined by the setting of the torque wrench to thereby proof test the holding power of the anchor. Various means can be provided to secure the anchor under tension.
