A guidance system merges a descent mechanism with a tensioned rope to aid in safely lowering a stretcher, whilst ensuring it is kept at a safe distance from the surface. This technique becomes particularly useful in challenging environments, such as the rocky terrains commonly found at the base of cliffs, which make transportation to level …

Anti-gravity (also known as non-gravitational field) is a hypothetical phenomenon of creating a place or object that is free from the force of gravity. I love the word, hypothetical! – Very non-committal. You can play in a sandbox of “theory” and never be wrong. However, the other side of theory is a “proving ground”. So is …

Class 5 Litter Handling It may be necessary to lower the litter and rescuer past a roof or overhang. In this event, it will often be best for the litter tender to get his or her legs through the spiders or above the spiders so that he or she can hold the litter away from …
Let’s take a look at the Petzl REEVE carriage pulley and some of its common uses. The REEVE is made from two high-efficiency pulleys mounted onto a rigging plate. This design simplifies setting up rescue systems on a highline by reducing the amount of equipment needed as well as reducing the overall height of …

Over time, we’ve found this style of deflection offset to be really fun. They have their limits, as with any system, but strength (when properly rigged and run) comes easy and we appreciate the versatility it offers. Large gaps or spans are typically the MO for dynamic directionals. We used a standard A-Frame configuration on …

I found myself in a very compromising predicament. I had been running my gear company for less than a year and had been in search and rescue or the better part of 2 years and felt comfortable with what I had understood rope rescue to be. Fast forward a bit… I am standing on Bell …
Force Vectors In general, the greater the angle between two anchor points, the greater the stress will be on those anchors. It must be the goal of the technician to minimize all angles in a manner that will still accomplish the job at hand. The kind of stress that will be required of the horizontal …

Skate blocks are about the most amazing and versatile system known to rigging. Why? Low overhead. Low risk. High functionality. Super bomber! The question that most people have is, “Is it complicated?” No… Not at all. You can’t over tension this system. Take a look. Transcription from Conversations in Rigging Hi, I’m Richard Delaney …
Vision, training and rehearsing are purposeful events. Rarely can someone envision future events without understanding the past as there is no understanding or interpretation without history. Training involves coaching, education, drills, guidance, discipline and a host of other “things”… in short, “training” can be disastrous if done inappropriately. Rehearsing however is something different. Rehearsing involves …
