The Samson Log Impact Force Calculator (or "Rigging Wheel") is a handy tool for estimated peak loads on your Samson rigging lines in the field.
The Log Impact Force Calculator combines information from a Green Log Weight chart with the ratings for Samson Nystron or Stable Braid rope, and the length of lines in the system to help estimate peak force that will be applied in a negative-blocking situation. Operating the wheel is simple - on side A you use the wheel to find the mass for the piece of material being cut. On side B, the mass of the load found on side A is compared to a ratio of the legs of rope above and below the upper rigging block to get an estimate of the peak line tension the system will experience.
