About the Course
An understanding of mechanical advantage systems — in raising and lower modes — is crucial to all rope rescue technicians. Dealing with Mass and Force is aspects of consequence if not considered during operations. Working with tensioned anchor systems, guying systems, high directionals, load positioning and litter movement all come into play when building mainline systems. If these are areas of concern for you — or simply areas in your rigging and rope rescue knowledge that you'd like to strengthen — this course is for you.

Read MoreIn video 6.4 Pat Rhodes demonstrates the proper method of rigging a block and tackle (Aztec) with the pulleys at right angles to prevent the lines from crossing and creating friction. In video 6.5 the slack line instructor rigs the pulley in the same plane, and ends up with a rope crossing another. When I teach block rigging I always start with the blocks at right angles (Pat’s method), and immediately anchor the rope to define whether the MA will be even or odd. I finish with the attachment of the progress capture device.
