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 …
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 …
Excerpt from Gear In Use 2: Technical Rescue 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 the effective use of simple pulley systems. If a …

A mechanical advantage haul system reduces the effort required to raise a load. The mechanical advantage obtained is based on the pulley effect. 1. The Pulley Effect If we consider a load suspended on a rope, the rope passing through a pulley above the user, with the user’s hand holding the rope on the …

This is a repost from Petzl. These folks have it right! NOT A SINGLE PRUSIK IN THE SYSTEM Why one Utah SAR team transitioned to the MAESTRO SEPTEMBER 29 2020 ON-SITE RESCUE “Give us thirty seconds,” said Utah County Search and Rescue Incident Commander, Jared Hansen. Thirty seconds to transition from a raise to a …
CMC MPD ~ Two Rope Offset ~ TTRS The MPD allows you to go from lowering to raising without changing hardware. More than nine years of research and development went into the patented Multi-Purpose Device (MPD), which features major innovations in advanced technical hardware for rope rescue professionals. The MPD’s high-efficiency pulley, with an integral …
Ultimate – the best achievable or imaginable of its kind. Can we have The Ultimate Gear List for anything? Probably not, but we can put some thought into what that might look like. Before we get to the list, let us outline where this gear cache came from. In building this course with Jason Ilowite …

The MAESTRO combines the abilities of a progress-capture pulley and a descender for effective hauling, releasing and lowering of the load. The AUTO-LOCK system locks the load automatically and returns the handle to the stop position. Let’s start with a Petzl Maestro Overview! 1. Working principle The MAESTRO uses a pulley mounted on a …
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 …
