Negative blocking: can we find better words?

David,

In trying to determine what you want to convey my instincts would be to simply call this "blocking down" because that is what you are doing. It may not be necessary to imply or express the acceleration/deceleration phases of the wood falling ?

Also, if it is called "negative blocking", this may imply there is something else called "positive blocking".
 
I like the word dynamic because it keeps in my mind the dynamic load principle. It always reminds me to keep in the safe load range of the equipment.

Dynamic blocking.
 
How about bottom blocking or butt blocking? Being that the block is near the butt of the piece being removed and that you're securing the rigging line to the butt of the piece your removing. It also contrasts well with tip tying.

I generally use negative blocking, and even occasionally have started using positive blocking. It can be a bit confusing, but to me at least it made sense once someone took the time to explain it, and it seems to make sense when I've explained it to other people. But I agree that it's not intuitive when you first hear it and think we can come up with something better.

Dynamic and static? Drop block is good.

For dynamic and static I say,"let it run" and "hold it".

I have worked with so many folks that have no clue I have digressed to simple terms that I keep constant.

Example..I say to crew," we are going to lower that piece, block and porta wrap, blue line, let it run enough to clear me" simply understood by most I have worked with.

Bottom blocking or butt blocking? Crikey I thought snatching was a bit risqué!
 
I have used the terms Impact-rigging or loading, in the past. The suggestion being that its a fall-arrest scenario. Customers even seem to get it, and anticipate some drama. Negative rigging, seems more descriptive than Negative Blocking. Negative Blocking doesn't even suggest that theres rigging involved.

Attached, a way better pic than yours David.

I would use "negative blocking" for someone who thought we were going to do something easy, therefore an explanation along with instruction would follow. "Lowering" would be for someone who had some clue as to what to do. I think "load rigging" is pretty descriptive, good talk for the ho. Now, "snatching" would be what we would be headed out to do after work.

dynamic vs. static (load) rigging would by my suggestion too. somehow it makes perfect sense, doesnt it?
the only confusion might come up with the dynamic acton of the groundie on the lowering line, but thats not a big deal I'd say

negative blocking doesnt make sense to me, whats positive blocking please?
 
It's Free falling, then you "snatch" it back.
Negative blocking is a poor description.
Ps are you sure you don't "butt block" after work!
 
I think 'negative rigging' is a perfect description. When you rig from above, you are able to 'positively' affect the load by tip tying and/or pretensioning with a 'positive' load. When the load must be dropped below the rigging point, it becomes 'negative.' Compare it to a numerical chart with zero being in the middle with positive numbers on one side and negative on the other. The load drops below 'zero' and into the the negative zone below. It seems to make sense to me. Just my dos centavos.

We have always called it "Butt Catching", or "Butt hitching". The lowering line is catching the butt of the log in this configuration. As opposed to top/tip tying such as when the block is higher up in a close by tree.

"Butt hitching" is what I've heard it called since 1969.

Ditto, and what I still use. Simple and accurately describes what is being done most of the time. If something in a specific situation needs further description, I do so.

Like everything else that has to do with trees, you do and use as much as is needed, not as much as you can.

and just to be clear, I was looking for a term to use when conversing over internet, text or other media, not with the work crew during work.

example, like Bixler asked me what is the proper term used for it a few weeks ago; so he could put it in his latest video title. he ran it by me to make sure he wrote it right.

Now, on the job, if I'm standing on a spar and I want to rig the logs down....

I'll simply say to the guys, "lets rig these logs down".

Also, blocking is in a lot of your suggestions. But I predict that the X-Rigging Rings will replace most blocks, even in negative blocking/ negative rigging. (especially with this new configuration I've been using; not shared yet)

After all this thread, I'm now thinking, NEGATIVE RIGGING is the best term to use.
