Dynamic Hauling with A-Frames and Monopods in Confined Space Rescue

Lance Piatt / Artificial High Directional AHD, Blog, Confined Space Rescue

In high-stakes rescue operations, especially those involving confined space entries, dynamic directional hauling systems offer critical advantages. This blog explores how to configure and operate a dual high directional setup—an A-frame paired with a monopod—to manage complex terrain and shifting load paths. When used with mirrored twin tension systems, this strategy creates a stable and
