High Tension Highline Rigging Mastery for Technical Rope Rescue

The ability to span a canyon, river, industrial void, or structural gap is one of the most demanding skills in advanced rope rescue. While offsets, tracklines, and guided systems are essential tools, the true test of technician-level capability is the high-tension highline. Unlike everyday rigging, high-tension systems do not forgive misunderstandings in geometry or guesswork […]

Why Parallel Haul Systems Don’t Double Mechanical Advantage in Rope Rescue

Debunking the Myth of Multiplying Mechanical Advantage In technical rope rescue, clarity and precision matter—especially when it comes to understanding mechanical advantage. One common belief that continues to circulate in the rescue and rigging world is that two parallel 3:1 systems hauling a single load equals a 6:1 advantage. It sounds intuitive. It looks clean
