This report covers the field tests conducted October 27 and 30 at CKAFS Pad 1-2 on 8-10 inch double-helix ground anchors. The objectives of the tests were to determine whether the 8-10 inch anchors will provide the holding force of 18,230 lbs. required for each of the 12 guy cables of the CEFAR YONDER expeditionary mast, and to evaluate the use of the Ackley Model 32H Hydraulic Impact Wrench in driving and removing the 8-10 inch anchors and determine the best method of handling the wrench during these operations.
