- Craig Bachmann, Lead Arborist & Manager at Tree133 LLC heads into the lab to take a look at minimizing load forces. Craig shows us it's all about the angles.
Craig Bachmann is a card carrying OSHA-30 Safety Trainer. Certified Arborist, Certified Tree Worker - Climber Spec., ISA Qualified Tree Risk Assessor, and SDOT Tree Service Provider.

Sorry for all tree workers who've never heard of those concepts. This is so crucial.
Plus tree work is waaaaay more fun when well planned and executed! Love it
An idea born out of laziness - if you can't be bothered climbing, why not just swing over to opposite limb to install another pulley and run rigging line through it, then swing back to make the cut?
Then you're almost perfectly compressing two opposite limbs.
Top video. Retrivable rigging rings are great for a high angle rigging point as you can set them in the crown of the tree when you set your climbing high point. When your finished rigging they can be removed remotely to save you climbing to the top of the tree again.
Absolutely outstanding. I am going to make this mandatory viewing for my crew.
Thank you for sharing this, a wealth of knowledge that will improve the way I work.
I’ve saved this video for new guys
This was absolutely informative! Thank you for sharing.
This guy is the best rigging teacher I have seen on TH-cam
No, not everyone has common sense. A great reminder of how to minimize a potential hazard. A great video for any crew to review and memorize. Thank You. Great illustrations and passionate commentator.
So clearly put. Craig is a great instructor!
Agreed!
VERY WELL EXPLAINED THANK YOU
Well done video.
This is such a good dang video
Annoying background music!!
Very nice brotha!
This was simple and clear. Thank you.
great info thanks
Excellent video,with very important Information.
Great information!! Thank you!!
Fantastic information in this video
Great info ! Awesome example of the physics applied to tree rigging!
Awesome stuff!!!
excellent explanation, thanks!
Awesome video! And thanks for the recommendation to read Joe Harris' paper. Much appreciated!
A good book to get that really goes into depth on statics is “engineering statics”. Nothing to do with trees but it’s a very cut and dry way to learn more. I think every arborist should be required to look into these kinds of issues. Incredible detail On explaining a subject that is hard enough, well done
Thanks for sharing! I know this video and the original article must be saving lives and property daily. The knowledge is already out there, but this is a great model for demonstration!
Absolutely!
Thank you for the explanation
Great webinar! 14:30 There is actually an upward bending force. Blocks at both points reduce friction pulling the two points together. Having friction at hinge point would reduce this somewhat.
I'm sending a link to my ground guys and telling them to start at 7:00...great info
So would it be better to rig off longer limbs them self and redirect to a higher point to create less force/torque vs just a higher rigging point? I was say so huh
Which block will take a greater share of the load when we have a redirect up high? For example if I had a larger WLL block and a smaller WLL block, which one would I want up high vs out on the limb? I'm assuming the larger one up high...
I'd think so. The angle is much smaller there.
That was very interesting. It's a real shame about the terrible drone of irritating music. I was half expecting him to break out a craft knife and a glue gun, to start creating some rubbish 'diy hack' . I swear that is where you got that music !
But with regard to the content, great. Most arborists will know these basics, but there is always something to take away. For me, I was surprised that I'd be better off frictioning from the limb (given the scenario) rather than getting the gs to bear it. Now it's been pointed out, it's obvious !
What about going higher then the same angle 📐 as the limb would they Create a - in the torque / forces?
3:55 that was so hard to watch - you just described a scenario where no one involved has any knowledge or understanding, and has put no thought into planning... and, quite frankly, has no business doing what they're doing.
Where can I get that shirt?
Great information, but difficult to listen and understand with the annoying music playing over his talking the entire time. Are all your videos like this?
Noted, they are not!
this feels like calculus.
The background music only makes it difficult to hear what is being said.
