TTRS Anchor Systems with Artificial High Directionals for Two Person Loads

Lance Piatt / Blog, Two (Twin) Tension Rope Systems, Two Rope Offsets

Technical rope rescue demands anchor systems that are strong, efficient, and designed for redundancy. Building TTRS anchor systems with Artificial High Directionals (AHDs) is one of the most effective ways to achieve these goals, especially when managing a two-person load such as a patient and attendant in a litter. By combining the principles of sound […]

Using the MAESTRO as a Belay Device in Single-Tensioned Rope Systems

Lance Piatt / Belaying, Blog

Turning the MAESTRO into a Belay Powerhouse In technical rescue operations, redundancy is never optional. Even when using a single-tensioned rope system (STRS) for primary load management, a belay line must always be present to protect against mainline failure or loss of control. While devices like the ASAP provide passive fall arrest, sometimes a higher

Lowering with Confidence Using the Single-Tensioned Rope System

Lance Piatt / Blog, General Rigging, Mainline Systems and Operations

A Lowering System Built on Simplicity and Redundancy The Single-Tensioned Rope System (STRS) is a rope rescue method that uses one rope to support and lower a load, while a second, redundant rope acts as a passive belay. The defining characteristic of this system is its asymmetric loading: only one rope is actively under tension
