Dynamic Forces and Shock Loading in Horizontal Track Systems

Lance Piatt / Blog, Designing Your Processes, Mainline Systems and Operations, Principles of Learning, Two Rope Offsets, Two Tensioned Rope Rescue Systems

Dynamic Forces and Shock Loading in Horizontal Track Systems In rope rescue, most failures come from what wasn’t seen, not what wasn’t built. A system can be geometrically perfect, the anchors flawless, and the tension within the limits of every catalog rating—until motion enters the picture. Once a load begins to move, the numbers change.Ropes

Debunking the myth of parallel mechanical advantage

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

Lance Piatt / Blog, Designing Your Processes, Mainline Systems and Operations, Mechanical Advantage, Twin Tension Rope System, Two Tensioned Rope Rescue Systems

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

Gin Pole AHD rope rescue

Lance Piatt / Blog, Portable Anchors, Two Tensioned Rope Rescue Systems

In rope rescue, artificial high directionals (AHDs) are force multipliers—not just for mechanical advantage, but for terrain navigation, edge management, and operational flow. Among the most versatile and efficient of these is the gin pole. Whether used in confined space, industrial tower rescue, or wilderness cliffside extractions, a properly configured gin pole offers clean vertical

Two Tensioned Rope System Enhances Lowering Safety

Lance Piatt / Blog, Twin Tension Rope System, Two (Twin) Tension Rope Systems, Two Rope Offsets, Two Tensioned Rope Rescue Systems

When lives—or critical equipment—must be lowered from lofty heights, there’s no room for compromise. Traditional single-line lowers place the full burden on one rope, one device, and one chance to get it right. The two tensioned rope system rewrites that script. By running two identical ropes—each through its own Maestro descender and edge protector—you gain
