Highline systems are among the most advanced rope rescue tools. They allow teams to move patients or gear across terrain that would otherwise be impassable — spanning rivers, cliffs, gorges, collapsed structures, or even urban voids. When done correctly, highlines are efficient and controlled. When done poorly, they can overload anchors, increase risk, and endanger […]

When to Choose an Offset Instead of a Highline in Rope Rescue – One of the most common choices in rope rescue is deciding between a highline and an offset system. Both can move a patient or load across complex terrain, but they solve the problem in very different ways. A highline acts like a

Norwegian Reeving in Highline Rescue Systems are essential in technical rope rescue when terrain, distance, or obstacles prevent direct access. Among the reeving methods used to move a load across a span, Norwegian reeving is one of the least understood. While Rigging Lab Academy has touched on it in gear overviews, the practical details deserve

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

Mainline and Belay Operations in Horizontal Track Systems In rope rescue, tensioned track systems are among the most complex setups a team can face. Moving a litter horizontally across a canyon, river, or urban void requires precise control of forces, anchors, and redundancy. The difference between success and disaster is often in the management of

Twin Tension Systems in Horizontal Tracks for Rope Rescue When a litter is moved across a horizontal track line, rescuers are managing one of the most demanding rigging challenges in rope rescue. Forces on anchors are amplified by sag angle, span length, and live load movement. Traditional single-line tracks rely on one rope for the

Why Sag Is the Silent Killer Ideal sag in tensioned track system for rope rescue is not an easy thing to figure out. If you’ve ever stood under a loaded tensioned track line, you know the truth: it’s not the rope that fails first, it’s the anchors. They groan, creak, and sometimes shift under loads

Mechanical Advantage Choices for Twin Tension Rope Systems Twin tension rope systems (TTRS) have changed the way modern rescue teams operate. Instead of one mainline and one belay, both ropes share the load equally, providing redundancy, balance, and smooth control. But while the setup looks clean, the question comes quickly in the field — what

Integrating Mechanical Advantage into Cross Haul Systems Cross-haul systems are one of the most versatile tools in the rescuer’s rigging arsenal. By using two opposing haul lines, teams can precisely move a load horizontally or diagonally, making cross-hauls ideal for guiding victims across rivers, canyons, industrial voids, or unstable terrain. But as loads increase or

The 20–80 Rule in Action: Building the Minimal Mechanical Advantage Kit In rope rescue, complexity can be your enemy. Too many devices, too much gear, and too many choices under stress can slow a team down and increase risk. That’s where the 20–80 Rule comes in: with about 20% of the gear, you can accomplish
