Arizona Vortex Configuration Guide for Directional and Anchor Frame Rescue Systems

Lance Piatt / Anchoring, Anchors, Arizona Vortex, Artificial High Directional AHD, Blog, Designing Your Processes, FAQ-Frequently Asked Questions

The Arizona Vortex is often taught as a collection of individual configurations: tripod, A-frame, gin pole, sideways A-frame, and easel-leg variants. But in the field, those configurations are never selected in isolation. Terrain, edge conditions, anchor availability, hauling direction, team size, load path, and operational constraints all shape the decision. This project reframes the Vortex […]

Teaching the Twin Tension Rope System in the Classroom

Lance Piatt / Blog, Two Tensioned Rope Rescue Systems

The Twin Tension Rope System — TTRS — represents one of the most significant shifts in rescue rigging philosophy in recent decades. For a long time, the standard approach meant one tensioned mainline doing the work while a second rope sat in a slack belay configuration, ready to catch a failure but contributing nothing to

Mechanical Advantage and Anchor Systems in Rope Rescue

Lance Piatt / Anchoring, Anchors, Blog, Mainline Systems and Operations, Mechanical Advantage

In rope rescue, mechanical advantage and anchor systems are never separate subjects. Every haul system depends on an anchor, and every anchor must be capable of resisting the forces a mechanical advantage system creates. That relationship is often misunderstood. Rescuers may focus on the efficiency of a 3:1 or 5:1 system, yet overlook how redirects,

Elevated Anchor Systems in Technical Rescue

Lance Piatt / Anchoring, Anchors, Blog, Elevated Anchor Systems

Understanding Artificial High Directionals as Structural Systems Artificial High Directionals, often referred to as elevated anchor systems, are sometimes treated as specialized accessories used only when terrain or structure presents a difficult edge. In practice, they are much more significant. These systems function as structural components that influence geometry, manage force vectors, improve movement efficiency,

3-Point Anchor Systems in Rope Rescue

Lance Piatt / Anchoring, Anchors, Blog, Designing Your Processes

Anchors Are the Foundation of Every System In rope rescue, every system begins—and ultimately depends—on the anchor. Whether you are lowering, raising, or managing a directional line, the integrity of the entire operation is tied to how well the anchor system is built. A failure at the anchor is not a component failure—it is a

Highline Operations Roles, Movement, and System Control

Lance Piatt / Blog, Designing Your Processes, Dynamic Directional, Highline Rigging, Horizontal Rigging

A highline system does not succeed because it is built correctly—it succeeds because it is operated correctly. Most system failures occur during movement, not during setup. The structure may be sound, but without coordinated operation, control is lost, and forces become unpredictable. Highline operations are defined by three elements: Clear roles Controlled movement Coordinated input

Highline Configurations in Rope Rescue When and How to Use Each System

Lance Piatt / Blog, Designing Your Processes, Highline Rigging

Highline systems are not built from a single template. The configuration selected must match the terrain, the objective, and the level of control required. The mistake is not choosing the wrong gear—it is choosing the wrong system structure. Each configuration changes how force moves, how the load behaves, and how the team must operate. Understanding

Highline System Components Explained for Rope Rescue Operations

Lance Piatt / Blog, Designing Your Processes, Highline Rigging

A highline system is only as strong and predictable as the components that build it. While the overall system moves a load across a span, each individual element has a defined role that must remain clear and uncompromised. Understanding these components is not about memorizing parts—it is about understanding how each element contributes to control,

Artificial High Directionals When They Are Needed and How They Support Rescue Operations

Lance Piatt / Arizona Vortex, Artificial High Directional AHD, Blog, General Rigging, Mainline Systems and Operations, Twin Tension Rope System

Introduction Artificial High Directionals (AHDs) represent a decisive shift from basic anchor-based rigging into controlled, engineered system behavior. Teams that are competent in raise and lower operations often reach a point where efficiency, safety, and control begin to degrade—not because of poor technique, but because of environmental limitations. Edges, terrain transitions, and structural barriers introduce
