The Focal Is Not the System
Walk up to a focal in training and watch what happens. Eyes go to the plate, the carabiners, the cams, the sling angles, the way
Rope Rescue Rigging Physics: From Force to Measurement
One System, One Load Path A rope rescue system can be drawn as equipment, but it is better understood as a load path. Force enters
What Does Your Anchor Actually See? TMA vs. PMA Explained
If you can count strands, you can pass a written test. Three strands running to the load, call it a 3:1, done. That’s the answer
How System Orientation Redefines Anchor Physics
Beyond “Bombproof”: How System Orientation Redefines Anchor Physics 1. Introduction: The Myth of the Absolute Anchor In high-stakes technical rigging, the term “bombproof” is often
Managing the Edge Through Geometry Using Elevated Anchor Systems
In technical rope rescue, the edge is often where a manageable rope system becomes difficult. Ropes bend across abrasive surfaces. Friction increases. Mechanical advantage deteriorates.
Building Rope Rescue Team Competency
A technical rescue program is only as capable as the people expected to operate within it. Equipment, procedures, and organizational structure matter, but none of
Understanding Pulley Systems for Mechanical Advantage
Pulley systems have been used for centuries to move loads with greater control and less effort. The same basic principles once used in maritime rigging
The V Anchor System for Mirrored and Twin Tension Systems
The V-anchor can support several rope-system configurations with relatively little equipment. In this application, it provides a practical foundation for lightweight wilderness rescue using mirrored
Anchor Angles and Load Distribution
Anchor Angles and Load Distribution Anchor angles affect how the load is distributed between the legs of a multi-point system. The wider the angle becomes,
Fast Fours Mechanical Advantage System
Mechanical advantage systems are often selected by balancing two competing needs: the force required to move the load and the speed needed to complete the
