What type of anchor system maintains equal loads at each anchor point when the direction of the pull changes?

The correct answer is a non-directional anchor system, which is designed to maintain equal loads at each anchor point regardless of the direction of the force being applied. This characteristic is vital for situations where rescuers may need to adjust their position or the direction of pull during a rescue operation, ensuring that the weight and forces are evenly distributed. This helps to reduce the risk of failure at any single anchor point, ensuring both the safety of the rescuers and the effectiveness of the rescue operation.

In contrast, a static anchor primarily supports a load in a fixed position and is not designed to handle directional changes effectively. A dynamic anchor typically absorbs shock loads and can be influenced by the direction of the pull, leading to unequal load distribution. A directional anchor is specifically designed for scenarios where loads are applied from a particular direction, which may not guarantee equal distribution of forces across multiple anchor points if the direction shifts. Therefore, a non-directional anchor is the optimal choice for maintaining equal loads during dynamic situations in rescue scenarios.
