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.
A ground anchor setting and loading device for use with driven pivoting anchors of the type where an upward force applied to the anchor after it is driven into the ground by a rod or cable pivotally connected to the anchor and extending above the ground causes the anchor to pivot within the ground to a set position and where after setting the anchor, a continued tension force on the connection up to a predetermined tension force proof tests the setting of the anchor, the device comprising:
A ground anchor setting and load locking device comprising a base member, an adjustable length upright post extending from the base member, a rotatable socket carried at generally the top of the post and retained to the post, an arm projecting from the post rotatable with the socket, the arm terminating in a connector adjacent a free end of the arm spaced from the post, the connector including connection for an intermediate connecting cable, the intermediate connecting cable terminating in a hook remote from the arm attachable to an end of cable having an opposite end attached to an anchor driven into the ground such that upon rotation of the arm through a vertical arc, a tension will be placed on the anchor cable, a torsion wrench detachably attachable to the socket and having an adjustable settable maximum torsion force applyable to the socket whereupon by utilizing the torsion wrench to rotate the socket, the socket rotates the arm and the arm applies an upward force to the cable to initially cause the anchor to pivot to a set position and to thereafter apply a tension force to the cable having a maximum force determined by the setting on the torsion wrench.
A ground anchor setting and loading device comprising:
The method of setting and load locking a driven pivotal ground anchor, having a cable affixed thereto which comprises the steps of:
