Floating the Litter Using an A-Frame and Gin Pole Trackline

Patient Packaging and Litter Handling Floating the litter

Floating the Litter Using an A-Frame and Gin Pole Trackline

Steep angle litter work represents one of the most challenging scenarios in high-angle rescue operations. The primary challenge lies in ensuring patient contact and visual oversight while navigating challenging terrain. These conditions often necessitate the use of a carefully chosen and highly functional system to ensure efficiency and safety, especially when personnel are limited.

Advanced System Setup: Arizona Vortex Combination

For this scenario, we utilized a full Arizona Vortex setup in a dual-segment configuration. The upper segment is configured as an A-Frame, while the lower segment serves as a monopod or gin pole setup. This hybrid system was selected primarily for its height advantages and operational flexibility.

Why This Setup Was Chosen:

  1. Height Requirements: Elevating the litter immediately off the ground minimizes the risk of patient contact with rough terrain and ensures smoother movement.
  2. Floating the Litter: The system was designed to “float” the litter and patient throughout the operation, avoiding the need to manually carry the load. This was critical given the steep terrain and limited personnel availability.

Key Considerations for Steep Angle Operations

When terrain angles approach 40°, the risks associated with steep angle rescues rise dramatically. A Two-Tension Rope System (TTRS) is the default choice for such operations, offering redundancy and control. However, the number of attendants and the configuration of the system are dictated by the Authority Having Jurisdiction (AHJ).

  • Personnel Load: Adding an additional attendant can increase the load on the system significantly, while insufficient personnel might compromise patient care and system efficiency.
  • Terrain-Driven Adjustments: The type of terrain heavily influences the choice of litter bridle setup and other system components. The attendant’s role is to assist with system progress and patient care rather than carrying the load.

Litter Setup and Rigging Details

The litter bridle setup is a critical element of the system, dictated by the terrain and operational requirements. For this demonstration, the classic Long Tail Bowline was employed, tying the bridle system directly to the litter.

Key elements included:

  • Anchors: Anchors were meticulously chosen to ensure system reliability and redundancy.
  • AHD Configurations: Proper Arizona Vortex setups provided the necessary height and stability for a seamless operation.
  • Trackline: Trackline height and functionality ensured the litter remained suspended throughout the ascent.
  • Patient Packaging: Secure and efficient packaging ensured patient safety and comfort during the operation.
  • Hauling and Lowering Systems: Robust systems facilitated smooth transitions and control during the rescue.

    My coder is trying to convince me to move to .net from PHP. I have always disliked the idea because of the expenses. But he’s tryiong none the less. I’ve been using WordPress on numerous websites for about a year and am nervous about switching to another platform. I have heard great things about blogengine.net. Is there a way I can import all my wordpress posts into it? Any help would be really appreciated!
