amsteel II crane spider legs.

Ah gotcha. I was going to say, we run 3/8 for moving wood around the yard and i know it's, like you said, good for 8k or so maybe more. For tree picks though, I'd rather run synthetics....getting smacked in the face with them is a little better than the chain. It does look like a pretty cool rig though...
 
Ive been using chains all year and would never go back to slings. Ill make a video this week and post it.

Chains are the way to go IMO
 
The chain system I use is just easier to use than a sling and offers total adjustability. We use a 15' chain but it can be chocked on a pick and then you can very quickly remove all the slack. You never have to remove the chain from the ball like a regular sling. They bite the wood better IMO. Mine is rated at 6800 but has a 4X safety factor so I am comfortable using them, we use 2 set at 180 on big wood.

Only downside I see is as mentioned you have to be careful as the op is bringing them to you as if they get caught on a branch and swing they could really hurt, haven't had it happen yet.

Mine are grade 100 chain, I need to figure out what the service life is on these but Im sure it far exceeds slings plus I only need 2 chains now instead of a box of slings.

Ground guy loves it to as it is so quick to take off, just need to unsnap one hook and done, don't have to even touch the ball.
 
I can see quick ground removal being a plus, but are you using them to balance odd picks, or just spar/trunk picks? We mostly use various length slings with tenex/stable braid spider legs for balancers(slow removal on ground, but picks barely move when rigged right). I'm also concerned about loading the gates of the chain hook snaps. Do you have a pic of your chain setup?
 
I do use them to balance picks, don't get super involved with that as I only have 2 chains but they are pretty quick to set. Probably not as easily adjustable as spider legs but they work for us. I am trying to put together a quick video of them in action and will start a new thread here about them.

Fwiw Treestuff has them in stock.
 
Hey x-man.
A quick question: do you prefer Amsteel II over tenex for example?
Going to buy me some slings and are a little bit I'm doubt weather to buy tenex it not ...
Thanks :-)

Peder, New England Ropes has a "crane kit" with 3 endurabraid slings. If you contact a dealer they can get it for you.

Thanks, mark :-)
I'll contact New England ropes to locate a dealer in dk.
Great crane video on stihl.com, by the way. :-) you could really see how well the slings balanced the sidebranches. Looks like a really good setup!
 
Just checked the Endurabraid winch lines on New England ropes website. The strongest line - 7/16 inch has a 13.900 lbs rating. And I expect you need a 1:5 safety margin, as with amsteel. Is that strong enough for most crane work? Just watched your crane video again and it looks like some fairly large pieces you are lifting in it. Do you use the Endurabraid slings for the logs as well or only for the awkward top picks?
Thanks a lot :)
 
Actually, the crane kit is 5/8" diameter. Winch lines are the same material but not spliced and such. This kit has two orange slings and one blue (30') to make it easier to differentiate while working. They have a protective cover over the eye splice (codura) to protect it and they have a rating stamped on them for vertical, basket, and choker.
 
Just found out that they are not sold in Europe as they are not yet certified (en) in Europe :-/
Guess I will have to go with some tenex slings.
The 5/8 " endurabraid are 29.000 lbs / 13 metric tons , wich is almost the same as the tenex tec 22 mm 140 kn . Sold by Freeworker in Germany.
Thanks mark for tips about length and colour! :-)
