High-Angle Rope Pickoff: the 'Y' Technique

摘要

WHEN WE TALK ABOUT HIGH-ANGLE rope rescue—in particular, pickoffs—we are talking about using two ropes to accomplish the task. One may be a main line and the other a belay, or safety, line. We may also be using a two-line system in which both lines act as a lowering or a hauling system in which the lines function as a safety for each other. The high-angle rope evolution is much different from the roof rope evolution, which employs a single line without a safety line for the pure reason that a life is in an immediately dangerous to life or health environment and time is paramount.
