Dynamic Testing of Pendulum Swing Balloon Logging System

Purpose

Project will involve rigging a two tree intermediate support arrangement to simulate a balloon and rigging a three guy line pendulum swing balloon system to this. Then tension will be monitored in the lines while weights are swung to simulate logging seq

Substitute Earth Anchor Test

Purpose

Ten 4" pilot holes will be augered approximately 5-6 ft. deep. A manta-ray anchor will be driven down each hole to a depth of 6-7 ft. Using test equipment, each anchor will be pulled out of the ground to test the holding capacity of the anchor.

Bar code feasibility study

Purpose

This study will be done to determine how well log design bar code tags withstand the rigors of the yarding process. 50 to 100 logs will be tagged with 3 tags being applied to each log; one on each face and one on the side near an end for a total 150 to 30
