4:1 pig rig (piggybackrig) variations

Rescue 3 Europe looks at variations in setups for external 4:1 systems, and bust some myths for common questions on WRT courses.

This video has been released for public viewing. It was originally part of the Rescue 3 Europe online conference and instructor updates, which is exclusive to Rescue 3 instructors. This online conference featured more than 50 pre-recorded videos in over 20 different languages, featuring equipment testing, talks from industry experts, and teaching tips and tools. Rescue 3 instructors who wish to access the online conference and instructor updates should contact Rescue 3 Europe directly.

Rigging plate testing

Rescue 3 Europe and Helix look at whether the use of a second rigging plate actually weakens other components in your system. Using DMM’s test rig, we show the tests we ran, and analyse the results.

8mm Prusik testing

Helix Operations have undertaken testing into 8mm Prusiks, which they have allowed us to share here.

The testing presented here highlights the importance of checking host rope and Prusik compatibility. While it is commonly understood that an 8mm Prusik on an 11m rope will typically slip within a bandwidth of 6-12kN, this remains a significant range of performance, and also does not address the ongoing performance of the Prusik post slip event.

The full report is available to download (PDF). Helix’s original write-up of it is at their website.
