What is recommended to use as a haul cam: triple wrapped prusiks or a mechanical rope grab?

Using triple wrapped prusiks as a haul cam is often recommended due to several advantages they offer in rope rescue operations. Prusik knots create a friction hitch that grips the rope securely when tension is applied. This characteristic is important in rescue scenarios where a reliable camming mechanism is necessary to hold loads effectively. The triple wrap increases the grip and enhances the security of the knot, which can be crucial in high-stress situations.

Additionally, prusiks are versatile, lightweight, and can be easily adjusted or removed as needed during the operation. They provide great control over the haul system and allow rescuers to manage loads smoothly, making them a favored choice in many scenarios over mechanical devices, especially for those trained in their use.

While mechanical rope grabs have their benefits, such as ease of setup and a quick release mechanism, they may not always perform as well in every rescue condition, especially when factors like rope diameter or debris are involved. Hence, the effectiveness and reliability of triple wrapped prusiks often make them the preferred option in many rescue situations.
