In the February 2023 issue of TCI Magazine, we reviewed some important mechanical concepts that arborists should know to better understand the likelihood of tree failure (“What Is Tree Biomechanics, and Why Should I Care?”). From that article, we learned that the likelihood of failure depends on two factors: the loads a tree experiences and […]
Biomechanics is the combination of two sciences – biology and physics. It’s the study of biological organisms from a mechanical perspective. Mechanics is the study of objects’ motion and is based on Newton’s three laws of motion. Those three laws are: If we want to understand how a bird flies or how a tree fails […]
Rigging is probably the most dangerous thing climbing arborists do. In addition to working aloft, which is dangerous in itself, rigging often involves cutting with a chain saw and, sometimes, large pieces of wood moving very quickly. When butt-hitching or blocking wood (which also is known as negative rigging), the anchor point of the rigging […]
