What is an Anchor System?
An anchor system combines ropes, slings, hardware, and the anchor itself to securely attach a load. These systems can be single point, multi-point load sharing, or multi-point load distributing.
Remember! An anchor system is only as strong as its configuration. Always consider how components work together to distribute load and provide redundancy.
Let's explore four common simple anchor systems for rescue operations:
Tensionless Hitch (High Strength Tie-Off)
The tensionless hitch maintains maximum rope strength in single rope anchor scenarios.
Key points:
Use on anchors at least 4x the rope diameter
Wrap rope at least 3 times around the anchor
Friction from wraps reduces knot stress
The tensionless hitch is ideal for securing far-side anchors in highline systems or river crossings.
Anchor Straps
Pre-engineered anchor straps offer quick, versatile solutions for single-point anchors.
For optimal use:
Double-wrap the anchor
Offset hardware points from load
Connect D-rings with one carabiner
Use a second carabiner on load side
This setup minimizes cross-loading or tri-loading risks.
Three-Bight Anchor
The three-bight system is quick to set up using open webbing.
Setup:
Create closed webbing loop with water knot
Pass around anchor
Secure with tri-link or carabiner
Consider the angle created, as it affects system strength.
Multi-Loop Anchor (Wrap-3-Pull-2)
The "Wrap-3-Pull-2" method offers additional strength from multiple webbing strands.
How it works:
Wrap webbing around anchor three times
Tie off with water knot
Pull two strands tight
One strand cinches anchor, preventing slippage
Pro tip: Position the water knot on load side against anchor to reduce stress on the knot and make it easier to untie at the end of the operation.
Conclusion
Mastering these simple anchor systems for rescue operations is crucial for any rescue professional. Regular practice and hands-on experience will boost your proficiency and confidence in the field.
Remember, successful rescues often hinge on proper setup details. By understanding and implementing these anchor systems, you're creating a foundation of safety for every operation.
