Litter Hauling Techniques Using Dual Capacity or Twin Tension Rope Systems Part 3: Via A Two Rope Offset

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

Industrial Skate Block Trackline System Upper Section (Part 1)

Hi, I’m Richard Delaney from Rope Lab in the Blue Mountains of Australia, and I’m working today with the Rigging Lab Academy. Today we’re working at Deschutes Brewery in Bend, Oregon. We are working with the same type skate blocks that we’ve been looking at in previous sessions, but this time we’re working in an

Litter Hauling Techniques Using Dual Capacity or Twin Tension Rope Systems: A Journey Part 1

What to learning something well?… “Do it yourself “.  Well, this isn’t always the case, but for me (right now) it is.  While not obsessed, I am really curious as to what a true minimally viable raise and lower system looks and feels like.  Remember the 3 types of learning?….. Vision, Auditory and Kinesthetic.  Well,

A Confined Space Rig: Anchors, Pulleys And The Haul Field in Rope Rigging Systems

Let’s continue with our pulley discussion. We have here a confined space rig, what I like to call it. It’s unique in that we have a tripod, and anybody who’s been around these things know they’re susceptible to tipping over, so it’s important, if you’re going to do something like this, that you have equal forces

Elements of Rigging – Bombproof Anchors – Anchor Considerations in Rope Rigging Systems

Well we’re talking about anchors. Let’s talk a little bit about the term bombproof. What is a bombproof anchor? Those of you in the profession of rescue work, and sometimes in the industry we refer to what’s a bombproof anchor? Well, it’s something that’s really strong that can pretty much hold everything. And looking at
