  1. You can control the spiderjack with your fingers and thumb, the lockjack for me seemed very hard to control. Pull the toggle and free fall!

     

    Then let the toggle go and your free fall is arrested.Very fast descents are possible but can be stopped at will.

    At this point I will confess that I use a figure8 with my lockjack on long hanging descents.

    As has already been mentioned a hitch can be better for branch walking.

    I love the Lockjack,I would always use it for my main rope but in combination with a hitch on any second rope.

    Just as VTs require a bit of tuning,the fine touches on a lockjack require a bit of practice.

  2. Nice pics Paul.Thats one of the most interesting jobs Ive seen.I had to cut out two cars once,that ran off the road and were lodged in trees on a steep bank.But it pales in comparison to a PLANE,haha.:thumbup1:And that tractor looks very handy too.

  3. does this happen often?

     

    Modern Arboriculture by Shigo,on page 2, there is a pic of a concave shaped Office Block in NZ, that was shaped to allow an existing Pohutakawa tree to grow.Its more common with footpaths and low volume roads.

    In my own experience,I have found it to be most common to transplant or fell trees from a new development.Then to start again from scratch with new plantings with maybe some of the existing trees retained.

    You get some good jobs eh Drew.

  4. Not of course that I'd ever use the system, I'm just off to give my Lockjack a polish :001_rolleyes:

     

    Do you use an extenson at all Dean,for the LJ?.For ascending or such.

    Sorry for the derail Adam.

    The O rig looks cool,especially with a revolver.
