Mark Chisholm, co-owner of Aspen Tree, has been using cranes to assist in tree work for years. Here, he demonstrates how he would attach a limb to the crane in a complex rigging scenario. Using limb balancing and tension, he executes a near perfect cut to preserve buildings on the jobsite and to make the safest environment for the climber making the cut.

Filmed live on location at ArborFest Expo 2019 using TreeStuff's Micro Rigging Lab to demonstrate complex problems and solutions on a tiny scale.
