Im with dave on this one as far as lifting the climber out side the tree it is much safer.

rob, the real issue i have is the new ANSI regs require the climber to have 2 attachment points during any climber hoisting. If the climber is flying though the air nowhere near there tree i can see the safety advantage to this. If the ball has been lowered through the tree or if the climber is being picked up inside of the tree and then being hoisted through the tree with their climbing line and presumably a buck strap attached to the ball, hook, load line, i see and increased risk of injury from the climber getting stuck on something, since the climber no longer has the ability to grab their friction hitch and rappel to avoid being torn in half, since the climber no longer has the ability to grab their friction hitch and rappel to avoid being torn in half

That is a very good point
 
It is an interesting discussion to start. I don’t have national stats, nor have I done any real statistical analysis..but most of the accidents I have heard about involving cranes and climbers are a result of the climber being stuck.
Getting smashed into the bucket
Getting dragged up a tree with their buck strap still attached to the tree because the signal man looked at the operator while giving the cable up signal instead of keeping their eyes on the climber
The horrible accident jay just referenced, still not really sure what happened, I think he was found on the ground with a broken buck strap
Being buck strapped to the tree and having the pick hit them.

It seems to me that the more freedom of movement the climber has the less likely hood of injury they have. What is actually gained by more attachment points in a crane assisted removal? Do we need to look at crane work as completely different than all other types of tree climbing?

Thank you Jo. This is my first ever crane cut. Makes me never want to climb and rig another pine. We did 4 90' pines in 9 picks.

The flip happened on a red oak about 120' or 130' from the pin. I'm persuaded, I'm moving to the dark side. I've never gotten so much work done with everyone just working a normal pace. It was sweet.

I know the cut is high, I didn't know for sure what would happen so I gave myself room to duck... didn't have to, the CO was a real pro.
It also never occurred to me to work with just a lanyard. I used my regular DdRT like working a spar. Not having an escape seems pointless.

Ha ha... can almost see the smile on your face...

I think your cut height was perfect...many people cut at their chest... a habit of cutting at head height is good especially if you are hiring cranes and getting different operators...you are putting your self in a safer position.

Nice to hear you had a good time
 
I guess the logical method of staying compliant to the new Z regs is to tie into the hook's master link with two climbing lines, one short and one long.

That would I believe offset the negatives of the set length lanyard, and still keep the climber relatively safe from being torn in half if something went wrong.

Or am I mistaken?

Another plus for the Kboom. I'm not behind a cab running controls, nor am I in an inclosed cab on the rear of a truck. I can stand anywhere and even be in the tree with the other climber. There is no cable to run down into the canopy. I can stand right at the tree and walk with the load to the LZ.
 
I gotta admit you're pretty darn good with them Jeremy, and run a pretty impressive operation as well.

I myself am still partial to hydrocranes, but like to think I have an open mind on the subject of Kbooms in this biz as well.

Big or even medium size eucs tend to put off seeds beneath them that sprout and grow into tall skinny trees reaching for sunlight called fastigiates in very large numbers.

One big euc can be surrounded by 30-40 fastigiates reaching for sunlight much like conifers do in a forest setting.

Do you mean Fastigiate: Having erect and almost parallel branches tapering toward the top, as in the Lombardy poplar.

or

Eucalyptus fastigata, Brown Barrel or Cut-Tail a common eucalyptus tree of south eastern Australia.


So, I can still tie in to a friction saver on a shackle with my lanyard through the hook?
 
That's acceptable in my understanding of the new changes. But I don't have the actual document in front of me. You have to buy it or something.

It's still a huge improvement nonetheless.

Uh boy!


2. Under section 5.7.13 The qualified arborist may be hoisted into position utilizing a crane if the arborist is tied in with an arborist climbing line and arborist saddle and secured to an anchor point ON OR above the crane hook or to the crane boom. The following procedures shall be followed when a qualified arborist is to be hoisted by a crane: (I only listed one).

5.7. 13.2 The qualified arborist SHALL use a second point of attachment on or
above the crane hook or to the crane boom while hoisted into position in the tree.

A problem I see with this. I use 12' to 20' slings having a joker hook on bottom to choke the limb. I usually hang too far from the hook rouse the safety lanyard. So that means I will need 2 climbing lines. Of course one could be short.
 
What if we used round slings hanging from the hook and had a clevis or equivalent piece of hardware hanging from it to choke on the limbs, and on that round sling was a rated cord tied with a prusik so it can be adjustable up and down the sling to clip your lanyard in as a second point of attachment??
 
I'm not sure that would fit in with"on or above the hook"
Not dismissing the idea but I some times have a crane bag there to


Maybe a single piece of climbing line. With spliced eye hooked above and we could be attached as srt. It would need a stopper at the end.
