MAESTRO and I’D allow for efficient hauling, releasing the lock at any time and a controlled lower of the load. The two devices have different ergonomics and different specifications (working load and efficiency). Hauling The MAESTRO’s efficiency enables effective use of simple pulley systems. If a complex pulley system is needed to increase efficiency, it …
All maneuvers must be done on two independent rope systems. These two systems can work in parallel (two haul lines) or separately (work rope and belay rope). 1. Examples of hauling with work rope and belay rope. All hauling and positioning forces are concentrated on the work rope. The belay rope is set up and …
Team Rescue Techniques for Hauling and Lowering with Petzl Maestro Read More »
I always appreciate great video. Video (to me) is either aesthetic or technical and trying to bridge both is tough. This video from CMC is clearly technical, but I really appreciate the angles of perspective. So often the “clarifying message” of “the how” can get completely lost if the angles are not right. The CMC …
Double CLUTCH | Using the CLUTCH In a Twin Tension Rope System (TTRS) Read More »
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 …
(This article was originally run in Firehouse October 1, 2019) Russell McCullar clarifies whether 15:1 is still relevant and says that fire departments should select gear and load limits that meet their needs. All Photos by Russell McCullar Not long ago, I was explaining to one of my students that our training agency was undergoing …
I’ve had a lot of bad ideas so I get pretty excited when I have a good one. The Crackerjack Group recently held a “flyer” of a class we dubbed The Dirtbag Clinic.. and it worked. The idea came about because we had some friends in town for the Mountain Rescue Association Conference and they …
The other day I walked into the studio (Neverland) armed with one goal for the morning… build a system that is Functionality Efficient in Gear Efficient in People Efficient in Physics AHD Based Small Team Based One Person Load Very Reproducible Raise Only Based (but with a margin of error that allows for downward adjustments… …
From Jason Ilowite… our instructor for this flagship course 5 Day Advance Workshop. So a little bit about the upcoming 5 Day Advance Workshop and why I think it’s important and valuable. I think the five day course addresses a problem that many of us, and I say us, I’m talking about fire service, rescue. …
So backcountry meets fire service… sounds like a battle of some sort. So while this “match up” is really neither epic nor epoch, this contest does have some interludes that hasn’t always faired well for either side. A while back, some well needed direction was given to the fire service in the form of recommendations …
Two Rope Twin Tension Mini Offset… Backcountry Meets Fire Service Read More »
Two Rope Offset Systems or “cross hauling” uses two identical working systems (normally). Now while some use a main-belay system, we are advocating a “two tension system” as it “halves” the amount of tension on both sides respectively, thus reducing the chances of any load related challenges… I am purposely not using the term “catastrophic …
