Technical rope professionals often need fast clarity on specific systems. Whether you are refining a Twin Tension Rope System (TTRS) or setting up a gin pole, efficiency, safety, and precision come from understanding how the system works—not just owning the gear.
Twin Tension Rope Systems (TTRS) TTRS distributes the load between two tensioned lines, with both lines capable of functioning as main or backup. This balanced redundancy improves control during hauling or lowering operations and offers greater safety margins in critical environments.
Key resources for TTRS:
- CMC DOUBLE CLUTCH TTRS KIT – Available in both 11 mm and 13 mm configurations for operational flexibility.
- Petzl Two-Tensioned Rope System Kit – Highlights mirrored tension and line sharing.
- CMC MPD Two Rope Offset TTRS – Discusses the value of the MPD device for seamless raise and lower transitions.
- Twin Tension Rope Systems – A foundational read for understanding twin tension during litter operations.
Gin Pole Setup and Stability Gin poles are versatile high directionals used to lift or redirect loads in both vertical and horizontal systems. Their setup requires thoughtful guying and load-path planning.
Start here:
- Gin Pole Rigging – Essential concepts and applications for building out a safe gin pole.
- Gin Pole Twin Bundle Horizontal Rigging – Focuses on horizontal applications and control side mechanics.
- Truck-Based Gin Pole – For vehicle-based high directionals.
- Gin Pole Rigging Stability – Explore the physics of guy lines and directional integrity.
- Gin Poles with Tom Wood and Vertical Rescue Solutions – This course provides hands-on walkthroughs on monopod construction and guying systems.
Suggested Learning Progression
- Read the core article on Gin Pole Rigging.
- Apply system-specific lessons from the Truck-Based Gin Pole.
- Reinforce with training through Gin Poles with Tom Wood.
Mastering these systems begins with asking the right questions and following through with structured understanding and hands-on application. When precision matters most, knowing how to build and operate TTRS or a gin pole setup is non-negotiable.
Peace on your Days
