? number of spider legs = more stable.

Heres a couple of pics of the chokers I use now, I wasn't very clear before I have used the bell and ball chokers, but I have switched to these because they are rated although harder to work with.

I think these are better. Keep in mind they are rated in the configuration shown in the close up picture(as are most slings...wire rope or synthetic). I have yet to see one rated as we use them. When we use them they bend 90* from the loop. I would like to see testing done on various slings to show what if any difference their would be to capacity.

A greater number of slings does not make the load more stable the placement of the slings does.

You're jokin, right?

I back Allmark 100%, I also have never seen a bell choker (ferrule/slide) rated for overhead lifting.

Norm, you are going back to the original post and good for you for agreeing with me.

On crane jobs after I ran this post, I further reinforced to myself that the more slings on a pick, the more stable the load will be.

I don't care about what anyone says about possible loading on just two slings if a greater number than 3 is used.

the more slings, the greater chance you will have of NO movement as the pick comes off the cut.

I would never use something rated so weak as to cause failure if just two slings held all or most of the weight anyway.

As a climber and crane owner, I want less movement in my crane picks and the more attachment points the better. (yes, I usually just use 3 though on most limbs, and two on fat trunk picks).
 
this thread is like the night of the living dead. if you want my opinion read the thread. this thread is pretty self explanatory. xman you tha man.
 
I stand by what I said, if you put a single sling precisely above the center of gravity the pick will not move at all and as for the original diagrams no matter how many slings you have on the load if you set it down unevenly on a load the slings on that side will come slack and the load will roll.

Once again the only thing that makes a load stable is having the hook directly over the center of gravity, for example imagine a load with a hundred slings on it but the hook is closer to one side of the pick than the other( not over the C of G) then when the pick is lifted the load will move until the C of G is under the hook.

I see your point and i wouldn't mind seeing some testing either, but from a crane operator's perspective the capacity wouldn't change because its still in a choker configuration.

I do not agree at all.

i know that i can put that hook quite a bit off of center and place enough slings and it will stay in that same position.

now if you are talking using all the exact same sling lengths, then yes. but if you are tying spider legs, where they are all tight at the same time; NO.

And Jeff, BTW, you brought out the worst in me months ago, so I put you on ignor user a long time ago. First person I have ever placed on ignor on tree buzz since I started viewing tree buzz. I don't care to read anything you have to say. I despise you.
 
the hate hurts you more than me. go pray about what you feel. you'll find the problem is not me, but yourself as you don't know me. so all these visions of hate are something you are broadcasting from your own personal life. haters hate like you, but ballers ball like me. go on and keep putting up pictures of yourself and your crane writing arbor x all over them. that will let us know you are real tree man. i give you props not once but twice and that is all you have to say? here is to the best rigger on tree buzz--- x man. ya know we'll run into each other one day. i just hope you don't try to make an a-- out of yourself. because you sure have on here with me twice.
 
sling lengths and number of slings doesn't matter look it up seeing as i can't convice you.

if an object can rotate around a point ie: a hook then it will always move so the C of G is under the hook.

go out to your yard, find a solid log and play with it for a while if you can possibly prove me wrong, post the pics and I will explain the forces for you.
 
For those that don't know what C of G is, its the center of gravity, the point of an object where the weight is balanced.

For example if you have a log which is solid on one end and hollow on the other the C of G will be closer to the solid end.

its not my opinion, its the laws of physics. <font color="purple"> </font>
 
I agree with the center of gravity but in picking limbs too often we cant attatch to thec/g or over it due to multiple limbs.

As far as a sling used in a choker config when we choke a verticle stem and pull up it is no longer in the config it is rated as. If we pick a horizontal limb that stays horizontal then we are. I wish I could do a drawing to show what I mean but havent got that yet.
 
Yes that was one of the reasons I listed for multiple slings, and I understand what you are talking about with the choker , but if you talk to an operator or inspector he would tell you it would be rated the same because there hasn't been any testing in that configuration(as far as I know).
 
As Im reading this thread all I can think is. . .

how SCARY x-man is. I'm trembling cause the rest of us are

so inferior to his vast knowledge, well said Jeff, Hate

puts up walls. . . . My teachers best lesson,

"YOU CAN LEARN SOMETHING FROM EVERYONE, EVEN IF ITS WHAT NOT TO DO."
 
ahhh shut up

I don't have the vast knowledge, such as others that have gone to 50,000 hours of crane training and built the world along side of God with a crane.

but i have real working knowledge and I guess i will have to take a big long branching limb and tie it with spider legs and take pictures. then set it down, tie it again differently and pick it up again to show that the hook can be in different possitions. or maybe i will learn something.

i didn't say i had vast knowledge anyway, ever.

i just let Jeff know that I still don't like him and if he wonders why i never respond to his posts, it's because i can't read them. Everyone on the buzz has someone that they don't like and Jeff is mine, that's all.
 
ohh... go beat your wife... tell her how awesome you are she'll believe it; after you beat her awhile.... the rest of us won't. go buy a two thousand dollar dwarf/ stunted/ Sequiadendron Giganteum and go plant it in ya a--. i think i would have took a vacation to Hawaii. then again, you need another totem too your greatness. and by the way i know you read these post i write, it would be impossible for you not to, with your personality. you don't respond because you can't win. loser boo yaa i don't waste my time hating or disliking you, i think your arrogance is amusing.
 
I'm just sayin' when I'm paying an operator by the hour, IM NOT SPENDIN ALL DAY TYING SPIDER LEGS AT DIFFERENT LENGHTHS TRYING TO MAKE THE "PERFECT PICK". SLINGS OR CHOKERS HAVE ALWAYS WORKED FINE FOR ME. . . LET'S NOT OVER COMPLICATE THINGS REMEMBER THE OPERATION MUST BE PRACTICAL AND TIMELY TO BE EFFICIENT. TWO QUICK SMALLER PICKS IS FASTER THAN A BIG PICK THAT TOOK YOU TOO LONG TO RIG. DO THE MATH, BET IT'S HARD TO USE A CALCULATOR WITH THOSE 11 INCH BLADES HANGING OFF YOUR KNUCKLES.
 
I'll be posting a video of some of my crane removals with using spider legs and we'll see then if you think it takes a long time to tie them.

I don't have to use a calculator on the job, common sense there. But I could easily cut your throat with them.

Every job &amp; every pick is at least minutely different. Sometimes i like to stand up picks with a sling or 2. Sometimes i like to spider leg 1/2 of a decent size tree &amp; bomb it out in 1 pick. Sometimes TiersonB's Rig'em &amp; Roll can't be beat!
