Using Crane for Tree work pt. 2 | Manipulating HUGE logs using this technique

[@jasonturney]

Thanks for the tip just getting into doing crane work

[@jasonturney]

Your videos have been helpful to me with getting back into tree work

Right now my neighbor is using a crane to cut down a leaning 80 ft tall oak. Amazing to see it done live.

Nice work 💪👍👍👍

I don't do much crane work but the front of that crane looks like it's so flimsy on that stack of wood lol

[@SLOCLMBR]

Probably fine that close with a bigger crane, gotta be careful with that technique. Can get into a side loaded situation really easily. Or worse, have a heavier piece than you bargain for.

[@treemands]

Shaky looking rear stabilizer cribbing...especially for a bit of shock load involved. Why not just slam the stick?

[@neild7971]

Side loads?

[@freedomfamily1358]

The hindge wont do a pop break if you do a 70 degree or open face notch fyi

[@br-dj2ti]

Hey buddy I really love your videos you think you can ever get into doing like raw videos of you up in the tree that would be great just curious why you don't do that

Dude, No. 1). A little bit of dynamic force when the log slides off of the stump is not ok. You aren't going to flip the crane but you could damage the boom, cables, etc. 2). Side loading the boom...Again no flippy flippy, but could breaky breaky. 3). This one worked out because you were lowering the log back towards the crane so that he was increasing his chart as he lowered. However, you didn't mention that the crane might start off in, let's say, a 7,000 lb chart but if you were laying the log away from the crane then it could end up in a 2,000 lb chart by the time the log "slides" off the stump. A 7,000 lb log dropping 8 inches and then coming to a complete stop could be a disaster to a crane in a 2,000 lb capacity chart.

All true, there are lots of ways to do this WRONG and have major issues. like most of tree work a technique must be understood in a deep way to avoid many of the less obvious pitfalls like the ones you mentioned. The advantage of the correct use of this technique is that the crane shouldn't ever see half of the weight of the load. As long as the log is tipped over when it slips off the edge of the stump the crane sees little change in load as it drops and as the bottom edge hits the ground especially compared to attempting the same with the load with the CG fully supported by the crane

Id like to talk to a certified op about this but in my experience i can find multiple reasons why this isn't a great idea!

[@Stridertrees]

I am also a certified Crane Op, and you're right in that there are risks associated with this technique, but there is also extra margin that isn't obvious in the video given the size an limits of this particular crane in this particular setup.

[@alexmatthews2332]

@Stridertrees I'd be totally down to see in depth crane vids I'll watch all of it lol! I got a 9 ton this past year to get my feet wet. We used to hire 25 tons in the area.

You should come to the south and cut some trees with us.
