Conference

The tree climbing and arboricultural conference is finished until next year! The “Trivect “and “Planning for Maintenance, not removals” presentations were well received.

Graeme will be heading up to World Arbor Camp tomorrow to do some additional talks.

The material from the presentation is included below.

The program hasn’t been updated since I wrote it, normally before this kind of thing would be shared it would go through fairly vigorous bug testing.

If I get some time to neaten it up I will fix some of the major bugs. I will point out some major things to consider:

  • Don’t use angles outside of -90 and 90 degrees. Apart from being completely pointless, in a practical sense it would be dangerous. One day I’ll write some restrictions that stop those kind of numbers being entered
  • Have a good think about what the program is telling you to do.
    • Is it realistic?
    • Will my high points handle that kind of load?
    • Are those vertical components what I would expect?

Months away from this years ISA presentation in Sydney, all is going ahead as planned.

As stated earlier we’ll be presenting on Trivect rigging and “Planning for maintenance, not removals”.

Trivect has generated a surprising amount of interest and dialogue. Perhaps the biggest question has been “What is Trivect?”

Trivect is a rigging system that uses three pre-tensioned lines to lower a load. When the load is separated from the tree, the system is designed so that the load remains stationary.

This allows for a very high level of control.

Just got back from a fantastic morning with the guys at Jim’s Trees and Stumps. We presented some of our material on the topic of large tree removal and rigging techniques.

We touched on a lot of our technical tree removal, and unveiled for the first time, our video of our triple point lowering system in action (Trivect). This will hopefully be posted on our Youtube channel soon.

The Cannings and Atraes displays were still set up, with many tree lopping items of interest out for inspection.

It was great putting some faces to names, and hearing about some of the problems other climbers and business owners are facing in their various ponds nationally and internationally.

We’re always keen to be involved in conferences and presentations, and thank Jim’s Trees and Stumps for the opportunity to share some of our work.
