  • The orange rope goes through a block 60' up in  a redwood tree used as a redirect.<br />
The other end goes to a different redwood where the GRCS is installed
  • We had very good rope angle. Very little moment on the tree and low tension on the line.<br />
A dynamometer is attached to the green line and the orange line to measure tension.

  • Peak force measured was ~730lbs.
  • The system was pre-tensioned to >1300lbs<br />
before we started to make sure everything was working correctly.
