? number of spider legs = more stable.

I can't help but find this thread amusing and funny.

I hardly ever even try for a perfect COG pick unless the pick is through a hole in the roof or patio or something.

I like my picks moving away from me and towards the crane in a smooth fluid motion with just one steel choker and clevis, two if it's a codominant pick.

Time is money, particularly with a crane. Keep it simple, fluid and well within your load chart rating.

The only time I like alot of chokers is for taking 4-6 limbs in one pick off a main trunk.

All this talk about perfectly balanced loads on each pick
is silly unless you have no clearance and targets all around you.

I rig dang near every vertical trunk pick to hinge away from me and towards the crane.

In fact CO's that try and lift straight up and dangle wood near me annoy the heck out of me to the point I won't work with them again.

Very true you don't need a perfectly balanced pick every time, however if you keep practicing with choker placement and guessing where the C of G is then by the time you need a perfeclty balanced pick you can do it faster, easier and most importantly without the stress on your mind.
 
I don't have to use a calculator on the job, common sense there. But I could easily cut your throat with them.

Can't agree more. I personally favor spider legs over any other method for brush picks for most circumstances. Are they necessary? No. Unless you want to use the best practice available to minimize movement. If you don't mind a little spinning, shifting and/or roll over, then use one sling. Sure it is faster, but by how much and at what risk?

I have been doing this for a long time, and yet I still have a hard time telling anyone else what is the best way to do anything we do.
 
you guys should try a technique we used in setting structural steel. the two have the same problems: a need for high production and lower crane time. to solve this in steel they created multilift rigging systems. the systems have eyes with hooks spliced in one main line. so instead of making numerous trips with the crane they could set up to five pieces at once. i've been wanting to experiment with this technique in tree rigging.(i just don't do a lot of removals) i think it would be as revolutionary as it was to the steel industry. i like smaller peices it makes for less work on the ground, less gear intensive rigging, and less shock load. the trick with taking smaller pieces is the down time you have in crane time. with this standard rigging technique you can take up to five pieces at a time so that speeds up crane time. so on a decurrent oak that huge spreading limb became five smaller picks with one trip of the crane. the next removal i do with a crane i'll video. if any off you guys try it let me know how it works.
jomoco i told you that you'd like the shackles. got to love em. makes hard work easy
 
WOW i thought this forum was about grown men discussing techniques of getting trees on the ground without damaging property or themselves. all of a sudden i see so much integrity being compromised. WOW
 
if u can hang a 36"x 110' head leaning white oak in 24" tall pivot hedge then so be it. show me the pic's and u'll be the man i promise but till then im from missouri, folks!
 
hmmmm, Jeffry must be going off again.

Luckily I can't read what he says or I'd be tempted to stoop down to his level and spout off a bunch of crap back.

It has been tempting at times to take him off of "ignor user", but I shouldn't, less I might give in to bickering once again with him.

I'm tryin' to do my part to keep the forum professional.

What you describe in your post Jeff, taking multiple limbs per pick with lots of rigging has been going on in this biz for a long long time, and is only limited by the load capacity of the crane and your ability to cut the limbs in the proper sequence and avoid getting tangled up.

One of the recent crane removals I did here in Descanso was a dead hollow oak with a serious lean over a house. I used a series of steel and nylon chokers to ensure a relatively balanced removal of an equal number of limbs off each side of the tree, up to 8 limbs per pick, with me staying attached to the crane on a totally separate ball and hook from the rigging hook. The crane was a grove 90 ton hydro.

I have pics of the hollow lower trunk that prove my staying with the crane was a very good idea, and I must say that ANSI Z133 recognizing this need and allowing it into their standards was an excellent move as well, on their part.

Cranes can make removals so much easier faster and safer in this biz that companies without them have very little chance of competing against you price wise.

That hollow oak in descanso was a true widowmaker in waiting, and even though I thought I had anticipated just about everything on that stately old monster, it still had a big surprise just waiting to buzz and bite me about half way down!

That beehive only slowed me down for about an hour before I sealed them in with insecticidal gas and made that pick too!

good job dude. so you were christmas treeing large branches or breaking down large branches into smaller packages to be more timely on the ground? not questioning your good safe work but the methodology behind your strategy? i've often thought about both. while the rigging would be fun to take several large pieces. i don't think it would be efficient for my company as we are equipment poor but back strong.on most of my large removals i contract the debris removal from site by a loader truck. but we have to get it to the street and broke down into a manageable package often in tight spots. so rigging large pieces, for my outfit, is unproductive. for others with large equipment i'm jealous. one day this economy is going to pick up and baby i can sell. then i'll have all those nice toys to play with
