Here's the latest in a series of videos by Reg Coates showing the Stein RC3002 Dual Bollard in action. Note the use of color coded lowering lines and the way Reg lays the system out on the ground before installation. The Stein RC3002 dual bollard allows both lines to be controlled from one point.
Arborists throughout the country are showing high levels of interest in the use of advanced rigging techniques similar to that shown in the video below.
However, please be aware: these advanced techniques require a thorough understanding of dynamic loading, the rating of ropes and individual components and the safety factors applied to the final configuration. If you have any doubts about the safety of your tree rigging configuration contact Rossy Ross from Pro Climb - Rossy is the resident New Zealand expert on such systems.
