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 cost of rope rescue rigging and training, much less a rescue, has some inherent expenditures. There is the direct cost of the gear, which to some might seem like a lot, but in reality it pales in comparison to the costs of personnel and training. These can easily be broken down into professionals who

The I’D EVAC is a self-braking descender/belay device with the handle oriented to facilitate use on the anchor. Lowering with I’D attached to an anchor From Gear In Use 4: Rope Access and Confined Space With the I’D on the anchor, a person can be lowered to a workstation, or an injured person may be

Excerpts From Petzl Tech Tips When using equipment to belay or to maneuver, carabiners are a vital link in the safety chain. User safety often relies on a single carabiner. To avoid the risk of breaking or accidentally opening a carabiner, it is important to know how to choose and use them. Petzl designs carabiners

Key issues and risks When the rope is taut, the carabiner and the device are held in position by the tension. But when the rope is slack, the device and its carabiner can move about and become poorly positioned. So there is a risk of rubbing on the sleeve, or of cantilever loading between the
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

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

There can be a big difference between the theoretical efficiency of a pulley system and its actual efficiency. Here are test results from the Petzl lab. 1. Efficiency depending on the device used at the head of the system. The force required to raise a 100 kg mass was tested under several configurations with different
