Stationary Rope Technique Systems

An introduction to Stationary Rope Technique (SRT).

Vermeer Australia and Joe Harris, along with some of Australia’s most renowned climbers, have joined forces again to deliver the annual Vermeer Arborist Seminar Series for 2019. This year, the seminars focus on a topic that has become a talking point in recent years: Stationary Rope Technique (or ‘SRT’, formerly known as Single Rope Technique). The 2019 series provides the opportunity to learn about SRT and try out some of the different SRT systems available today.

We spoke with Joe Harris, internationally recognised trainer and tree climbing champion, who touched on the key elements of SRT as it relates to climbing arborists.

What is Stationary Rope Technique?

“Stationary Rope Technique (SRT) is a method of ascending, work positioning and descending from trees using an assembly of configured arborist climbing equipment such as ascenders, descenders or dedicated SRT work positioning systems.

When using SRT, climbers move up and down along a climbing rope – whilst the rope itself stays in the same place (stationary). In traditional climbing systems, the rope moves back and forth over the high point as the climber ascends or descends. This used to be called Doubled Rope Technique or DdRT, and is now called Moving Rope Technique (MRT).”

Benefits of Stationary Rope Technique

  • There is consistent friction at the hitch regardless of the number of redirects – therefore it is easy to achieve good rope angles and set multiple redirects
  • This technique may not require isolation of the tie-in-point, so it is quick to set in some configurations
  • With SRT, the use of ascenders or similar SRT equipment can make long ascents very efficient and fast
  • Only a single rope length reaching the ground is required
  • A wide range of equipment exists for ascending, descending and work positioning on stationary rope, and equipment can be configured into a number of different systems
  • SRT climbing systems can be used to perform almost any tree climbing task
  • The installation of multiple natural redirects has no impact on the climber’s ability to control the friction in the climbing system.

NOTE: It is very important to ensure that you understand the full range of functions of any SRT device, as well as the correct configuration and any possible risks or misconfiguration, before leaving the ground.

Presenter Bio Joe Harris, Cert. Arborist / Contract Climber

Joe is an internationally recognised trainer in Advanced Rigging and Forces, Advanced Tree Climbing and Aerial Rescue, and has presented at Arboriculture Australia and ITCC events.

In addition to presenting the Vermeer Arborist Seminar Series, he has presented workshops in Belgium, France, Germany and the US, and produced instructional videos for ART.

His achievements include being a two-time Australian tree climbing champion, silver medalist at the International Tree Climbing Championships, and an array of national achievements.

“Broadly speaking, the differences between SRT and MRT result in a different way of planning work within the tree. MRT climbers are said to see the tree in rows – planning to go out and back on each branch that is to be worked on. SRT climbers tend more toward working in columns – going up and down the rope with less lateral movement.”

The Vermeer Arborist Seminar Series kicks off again between August 9 and 31 in Brisbane, Melbourne, Sydney and Adelaide. This year’s one-day format offers a morning theory session followed by an afternoon practical climbing session to put these new techniques into practice. This year, attendees will leave the event knowing what SRT is and why they should use it, how to assemble safe and efficient climbing systems for ascent and work positioning, smooth climbing techniques with SRT systems, how to get the most advantage without any of the disadvantages, and tree work strategies to get the most benefit from their SRT climbing system.

In the interim, if you are interested in trying out any SRT ascenders, descenders or other devices, you can trybefore-you-buy in the Climbing Zone at your local Vermeer Parts Counter.

Aerial Rescue Vermeer’s Annual Arborist Seminar Series

Vermeer’s annual Arborist Seminar Series concluded in Adelaide last month, after a successful series of events in Brisbane, Sydney and Melbourne.

This year’s series topic was Aerial Rescue – providing assistance to a stuck or injured climber who is not able to get themselves down. More than just an important topic for any tree crew to be proficient in, provision for aerial rescue has been a legislated requirement on Australian tree work sites since 2016.

The 2018 series continued the established two-day format, with day one providing a foundation of theory and day two devoted to hands-on workshopping of techniques. This year Vermeer introduced a team of industry renowned co-presenters to support Lead Presenter Joe Harris across each location.

The 2018 seminar curriculum was based on the techniques and information found in the new Aerial Rescue Minimum Industry Standards, recently published by Arboriculture Australia Ltd.

During the seminars on day one the presenters explored topics like prevention and planning, accident warning signs, responding to an aerial emergency, types of rescues and rescue techniques. Building upon this knowledge, Joe and co-presenters Henk Morgans, William Mittins, Sam Hardingham and Barton Allan-Hall facilitated and supervised the completion of a simulated aerial rescue with attendees during the hands-on day two workshops.

Basic and complex rescue techniques were practiced, from scenarios where the wounded climber is responding and requires aerial assistance, through to situations with non-responsive casualties in the most challenging of aerial scenarios. Each simulated rescue utilised the group’s collective knowledge, with both the ground grew and climbing rescuer engaged to ensure a successful rescue.

Excerpts of the Aerial Rescue Minimum Industry Standard were provided to participants as part of the seminar course materials, providing a reference for ongoing practice of the techniques learnt during the seminars.

About The Minimum Industry Standards Series Books

The Minimum Industry Standards series, a first for the Australian Arboriculture industry, are industry-validated and peer-reviewed documents which describe safe and current methods of conducting work on Australian tree sites. These books have been developed by Joe Harris and Arboriculture Australia, and represent a significant step forward for the industry

So far, four variations of these Minimum Industry Standards books are available to purchase at Vermeer’s dealerships in Brisbane, Melbourne, Sydney and Adelaide. The list of books, which will be expanded upon, currently includes:

Aerial Rescue; Tree Dismantling; Arborist Ropes; and Arborist Knots

Meet The 2018 Series Presenters

Joe Harris: Once again participants were fortunate to have internationally recognised trainer, tree climbing champion and all-round nice guy Joe Harris on board as lead instructor to share his extensive commercial and competitive climbing experience.

Henk Morgans: Henk, a multiple-time competition winner who has represented Australia at international tree climbing events, co-presented with Joe at the Brisbane seminars.

Sam Hardingham and William Mittins Sam and Will educated and entertained participants at the Sydney seminars. Sam has won both previous Red Bull Branched Out tree climbing competitions, while William has over 20 years commercial climbing experience and is a contributor to the NSW Arboriculture Association and the National Practicing Arborist Committee.

Barton Allan-Hall: Barton is a four-time Australian tree climbing champion and previous world silver medalist. He is the current Australian tree climbing champion. Barton co-presented with Joe at both the Melbourne and Adelaide seminars.

Vermeer would like to thank all participants and presenters for their contribution to another successful Vermeer Arborist Seminar Series.
