Calculating mechanical advantage: the T-system 1. Assume continuous strands of rope have the same amount of tension. If we start at the point where effort is applied and assume that we apply one unit of tension (1T) then we can assume that the tension along this single strand of rope will be the same throughout. …

Mainline Rescue Systems – A New Course An understanding of mechanical advantage systems — in raising and lower modes — is crucial to all rope rescue technicians. Dealing with Mass and Force is aspects of consequence if not considered during operations. Working with tensioned anchor systems, guying systems, high directionals, load positioning and litter movement …
What if trees had ratings? What an amazing concept. John Morton, an engineer-scientist-visionary-technician, has been doing canopy studies for years and knows how they are affected by wind. Trees, whether alone or in community, are all influenced by wind and all have a certain “wind rating” to them. When SAR members show up on scene, and …

By: Jason Ilowite When we reach way back in our memory banks to when we were new drivers, I would venture to say most of us dreamed about rolling down the road in a nice new luxury or sports car some day. We all, however, recognized the importance of learning on the older model, that …
