What is a safe slackline backup? Use either static or dynamic rope, connected with knots to back up metal parts. Do not use ropes with diameter smaller than 9 mm. Webbing can only be used for lines shorter than 50m and well below 5kN base tension. BEWARE: forces can go above >20kN! In light of the recent fatal accident in Russia, many in the slackline community have questioned the reliability of their tiebacks and backups - especially for longer lines with high tensions. In order to shed some light on the situation, the ISA has performed 58 tests [...]
One of the few competitions which could take place after the Lockdown was the Rigging Masters at Bern City Slack with 27 Participants from 6 countries! The competitors had to prove their rigging and improvisation skills in 3 qualification rounds, a 6-person time trial in the semis and a direct shoot out with Augustin Moinat (CA) and Benoit Humm (FR) in the finals. Rigging competitions are meant to be engaging for the participants and entertaining for the audience. They are not a serious measure of someone's ability to rig slacklines. If you want to organise your own [...]

Rigger Certification in the USA After a successful launch of the latest ISA educational program in Europe, the Rigger Certification is finally coming to North America. The ISA Education Commission is proud to present the third Rigger cert this year, and the first one ever to be held in the US. This is not a course or a workshop, but the most expansive and comprehensive rigging evaluation available to establish an international standard for professional rigging. Why Get the Certification? The Rigger Certification is intended to help festival organizers, local clubs, and individual highliners with permissions, insurance, liability, and adding [...]
ISA:21 Highline Systems What is a highline? The ISA:21 Highline Systems Standard is a formal engineering definition and description of what a highline is and what the various components it consists of are. In addition to that, it also defines the forces that are acting upon the webbing, anchors and the highliner. In essence, it is a lot of fancy words, but it allows our partners and testing laboratories to communicate more effectively. Download Highline System Standard 21:2019 On one hand this standard provides a framework for highliners as well as slackline [...]
New World Record in Switzerland! Slackliners rig the longest hammock chain in the world – at the UNESCO World Heritage Site Sardona Have you ever wondered what highliners do when they are not slacklining? Sunday, the 23rd of June 2019, high above the ground with a mesmorizing view over the lower Segnesboden people are playing music, casually eating their lunch, doing acro and hanging from silks, All of this wouldn´t sound so unusual if there were actual slacklines involved. Instead, 4 very unslack, static cables and 26 hammocks paint the scene. These 26 hammocks rigged as a caravan [...]
Webbing slippage warning in Weblocks. We have identified the mechanism responsible for webbing slippage in webbing lockers (weblocks). During a test on a hydraulic cyclic testing machine, we found webbing to move through the weblock with every stretch and release cycle. We observed this micro-slippage of the webbing within the weblock. Read Full Report - Webbing slippage warning in weblocks The webbing was installed in single wrap without a tie-off so we could witness webbing slippage, webbing tailwalk, and a complete failure of the webbing locking mechanism first hand. The Solution [...]
