High-angle rescue scenarios demand precision, strategy, and the right equipment. This detailed case study explores the high-angle raise using a Vortex Side Frame, illustrating advanced rigging techniques employed by the File N-015 Rescue Response Team. The application of a high-angle rescue system in challenging environments, like cliffs and urban structures, demonstrates the importance of sound technical rigging knowledge.

The Role of the Vortex Side Frame in High-Angle Raises

The Vortex Side Frame is a versatile Artificial High Directional (AHD) tool designed to support complex rescues. As a modular system, it combines stability and adaptability, making it ideal for high-angle rescues where the edge transition is critical.

In this scenario, the team used the Vortex Side Frame to:

• Establish a secure edge transition for rescuers and victims.
• Provide optimal positioning for hauling systems.
• Allow efficient use of Twin Tension Rope Systems (TTRS).

By stabilizing the Vortex with properly aligned guy lines and anchor systems, the team created a robust setup capable of supporting both the mainline and belay line operations.

High-Angle Raise System: Key Components

High-angle raises require a carefully coordinated setup of equipment and techniques. In this case, the following elements were utilized:

1. Mainline and Belay Line Configuration
   • Dual rope systems ensure redundancy and safety.
   • Dynamic and static ropes were employed to balance elasticity and load stability.
2. Mechanical Advantage Systems
   • A 3:1 mechanical advantage was rigged to reduce the effort required for raising the load.
   • Pulley systems, such as the CMC MPD and Petzl ID, streamlined load control and progress capture.
3. Anchors and Resultants
   • Multi-directional anchors were used to manage forces effectively.
   • The resultant forces were carefully monitored to remain within the footprint of the Vortex Side Frame, ensuring system stability.

Rigging Details and Workflow

The team’s workflow highlighted the following:

1. Edge Transition Management
   The Vortex Side Frame was positioned as close to the edge as possible, allowing rescuers to transition smoothly. The setup included adjustable guy lines to manage resultant forces and maintain stability.
2. Load Hauling
   Using a Piggyback Haul System, the rescuers created a progressive mechanical advantage system, ensuring efficient lifting of both the rescuer and the victim.
3. Safety Protocols
   Redundant anchors and regular checks on all equipment minimized the risk of failure during the operation.

Lessons Learned

1. Stability is Key
   Proper guying and monitoring of resultant forces are essential for maintaining the Vortex’s stability in high-angle scenarios.
2. Equipment Selection Matters
   Tools like the CMC MPD and Petzl ID enhanced control and safety during the raise. The integration of pulleys like the Rock Exotica Omni Block improved the efficiency of mechanical advantage systems.
3. Team Coordination
   Communication and clear task allocation ensured smooth execution. Assigning roles for load hauling, belay management, and anchor checks minimized errors.
