Rigging Force Estimations - Speed Line

[Evan Sussman]

A cool little experiment / science project we got to do last week when the rest of our project got shut down by a big bald faced hornet's nest.

Comment with your estimates of weight, and peak line tension. Details are in the text of the original post.

Rigging Force Estimations - Speed Line

The other day Andrea and Evan decided to take guesses on load weight and line tension generated by speedlining a small Douglas fir top.

The top was about 80' up, and the chipper anchor was about 35' away. A pretty good scenario as far as minimizing lateral forces on the rigging point.

Post your estimated forces in the comments before you finish the video.

The top was about 5" in diameter, and 18-20' long. Pretty thin as it was crowded by the adjacent cottonwood.

Stay tuned. More to load estimates to come...
