The following tests were carried out in laboratories, with new devices and new ropes certified to current standards. Test results are given for information purposes only: they may be different with devices and/or ropes that are worn from use, or with other rope types or models. STATIC TESTS Slow-pull test carried out on different ropes; …
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 …
The following is from Loui McCurley/PMI Rope One of the MYTHS being generated about the new ANSI Z459.1 standard that was recently published as part of the ANSI Z359 Fall Protection Code is that this standard has introduced a prohibition on attaching TWO DESCENDERS to a SINGLE CONNECTION POINT on your harness. Before addressing that …

The MAESTRO, I’D or RIG descenders can be used in parallel in rescue situations, mainly with long rope lengths and smaller rescue teams. This technique enables a single user to simultaneously operate two devices. Advantages Even sharing of the load on the descenders Reduced potential extension of the system, in case one of the …

Staggering rigging anchors is a perfect way to spread the mechanical advantage system over a broad area, while at the same time, using the area very efficiently. The goal is to get as much “throw” as possible and to limit resets. There are numerous ways to do this and these are only two of the …

So what is a bombproof anchor much less one using an artificial high directional such as the Arizona Vortex Multipod? This question appears to stump, confuse and even frustrate many a rescuer and rigger. When it comes to high directionals, the complexity is even more concerning. It really shouldn’t though. Bombproof anchors have really two …

Gear Used In An English and Norwegian Reeving System – Overview You can use Reeves Systems on tripods, artificial high directional devices, or tension lines. These are great systems to keep rescuers out of the hazard zone, whether it be a limited rigging area where there’s a danger of a fall hazard, or whether that …

Excerpt from Gear In Use 2: Technical Rescue Inert suspension in a harness, even for a short time, can cause serious physiological harm. In case of an accident, it is important to intervene quickly with the appropriate technique. Self-rescue On sites where the main access could be cut off by fire, people must be ready …
Sterling Bound Loop Prusiks in Rescue Litter Rigging Hi, I’m Matt Hunt, the Work Market Manager here at Sterling, and we wanted to talk to you a little bit about our Litter Rigging System, which incorporates two pieces, the head end litter spider, and also the bearer tie-in, or the foot end. So what …

The patented locking mechanism in our updated CSR2 Pulley is easy to release under load, creating much greater efficiency with the lowering and raising necessary to a confined space rescue. The machined aluminum swivels at both ends of the system eliminate any potential twisting of the lines. This system is also an excellent choice for …
