Building an anchor system requires much practice and experience. In the end, simplicity and complexity are competency issues. Competency takes time to build and this doesn’t come without an investment of focus and purpose.
Building an anchor system requires much practice and experience. When dealing with structures, chose anchor points that are part of the inherent structure of the building. This includes columns, beams, anchors for window cleaning equipment, and elevator housings. Avoid corroded metal, weathered stonework, and deteriorated mortar. Avoid using vents, flashing, gutters, and chimneys.
When using a vehicle for an anchor, remove the ignition key, set the brake, and chock the wheels. Do not use the bumper. Connect directly to the vehicle frame using such items as the axle, cross member or tow hooks.
Often a desirable anchor is off to the side of a needed direction of pull. Ideally, they should be directly above and close to the fall line. When this is not possible (which seems to be more times than not) advanced anchor rigging skills come into play, namely, focusing the direction of the main anchor to a viable position.
Often, single point anchors are either non-existent or marginal, thus necessitating the need for multipoint anchor systems.
Rigging a backup or secondary connection to a separate anchor.
Available anchor points are not exactly where they need to be.
A directional shift is possible during the evolution
Multipoint Anchor Systems are generally when:
- Rigging a backup or secondary connection to a separate anchor point.
- An available anchor point is not located where “it should be”.
- A directional shift of the rescue load is predicted.
Anchors are the most critical component of any rope rescue system. The entire rescue is in jeopardy if the anchors are not reliable. Anchor systems are made up of two major elements:
Choosing the best anchor (i.e. boulders, vehicles, trees, and bolts), and
Rigging the anchor
