Load Sharing Anchor Adjustable Non Working 3:1
In technical rescue environments, adaptability and control are everything—especially when dealing with multidirectional forces or unpredictable anchor terrain. This tutorial demonstrates how to construct a Load Sharing Anchor (LSA) using an adjustable, non-working 3:1 system, allowing the focal point to dynamically shift with the direction of pull.
This system is designed to offer flexibility during setup and real-time adjustments during operations without requiring system disassembly or full de-tensioning. It’s ideal for rapidly evolving environments or when aligning anchors in awkward geometries.
System Overview
The system is built with:
- A 3:1 mechanical advantage setup on one anchor leg for precise tensioning
- Two half hitches to lock the adjusted length once the focal point is properly aligned
- An opposite anchor leg secured via a prusik hitch or static anchor strap
This combination creates a semi-adjustable, load-sharing anchor system with directional forgiveness—the focal point can shift under load without overstressing one anchor leg.
Step-by-Step Breakdown
1. Establish Anchor Legs
One leg features the adjustable 3:1 setup, allowing you to draw in or release tension to shift the system’s center.
2. Lock with Half Hitches
Once tensioned to the desired focal point position, secure the adjusted leg using two half hitches. This holds the system stable under load without allowing slippage.
3. Set the Opposite Leg
The other leg should be secured using a prusik hitch or an anchor strap. This leg is fixed, offering a point of passive resistance while the adjustable side dials in balance.
4. Optional Second 3:1
For greater precision, you can mirror the configuration by placing another non-working 3:1 on the opposite leg. This allows bilateral control over focal point placement.
Advantages of This Setup
- Directional Adaptability: Adjusts dynamically to pull direction—ideal for wide-angle anchors or indirect routes.
- Increased Control: Tensioning with a 3:1 MA gives fine control over leg balance.
- No Load Reset Needed: Once loaded, adjustments can still be made if designed properly.
- Training & Real-World Utility: Excellent for demonstrations, high-directional rigging, or real rescues involving offset loads.
Use Case Applications
- Rocky environments where anchor placement is uneven
- High directional systems where pull angles vary during movement
- Quick field adjustments where rope slippage or unequal tension needs correction without full rebuild
Final Thoughts
The Load Sharing Anchor Adjustable Non Working 3 To 1 is a smart blend of efficiency and precision. Its adjustability and lock-off capability make it a valuable asset in both training grounds and unpredictable field scenarios.
Whether you’re operating in mountainous terrain or industrial vertical access, this anchor strategy gives you what matters most: control, adaptability, and safety.
Peace on your Days
