Chuck skip the Pfanners and get the Cloggers ( for the warmer months!)Thanks Nick, I'll do that as I see they are in stock now.

Cloggers are out of stock for a few weeks so I ordered the Pfanners. I may be heading down to Indianapolis at the end of April for FDIC. If I do I'll be sure to stop at Treestuff to make sure the truck is full on the way back
Have to make sure I keep some $ kept aside for the crane course in Philly as well

You going again Chuck?

I really want to Steve. Do you think you may be there?
Hopefully my schedule will allow it. Unfortunately I had to miss the last tree expo due to a course I had to instruct on that same week. One of the issues of burning it at both ends as you know.

I'm planning on it! Considering CTSP in February also.

I ran into the same issue with another Tree company. They hired our 110 ton for a rental.
We kspec slings http://www.iandisling.com/single_path_polyester_slings_k-spec.htm
Half the bulk and weight of normal round slings with very high capacities.
These guys didn't like our slings. They pulled out a bunch of sliced amsteel slings, with no tags.
They had no idea what safe working load was vs breaking strength.
They thought I was nuts when I wouldn't let them use them.
We rarely ever use spider legs, long round slings with gunnbos on them give you the ability to put a couple half hitches in if necessary in a few seconds. If we use them they are only a secondary pick point, I always like to have a round slings as the primary support

Whats a gunnbos? The only thing is those darn shackles. If I had a piece I needed a 110 for I'd sling the primary lifting point too! I have yet to take a single piece with branches that needed to be balanced over 10k. To me that's a huge pluck even with a 60t.

Ahhh. I have seen those but none of the crane companies around here use them. I suppose a shackle is more failsafe?

A seasoned climber who knows how to work spider legs, is truly an art. To allow roll a with smooth pick is priceless.
Communication is key and time with the operator is other.

This is exactly why I use spider legs. 9400lbs.

No that was a 60t rental. I worked with the other crew today as my crew is down to me and one other guy. The owner went hunting. We had 5 ground guys who knew what to do. They did well with the pics. My back was killing me and I was hurting so the plan was to take them as big as we could and get me on the ground as fast as possible. 6 pics. 4 in the canopy and 2 trunk plucks. As long as I wasn't moving I wasn't in pain so I welcomed the processing time.

Awesome job Steve and I am glad to see you and others using "multi-point slings" as necessary for crane work.
For those of you who want to really see some impressive crane picks using "multi-point slings" (Note: individual slings are no longer referred to as "spider legs." A spider leg sling is an individual rope sling tied with a prussic onto another sling), come on down and watch us, or better yet, participate in the PA Crane Climber Class.
TCIA will be coming out this year with the latest revision to the Crane BMP Manual. In it, it will say that all dead eye slings (aka "multi-point slings"), as well as your crane friction saver TIP shall be tagged with the appropriate WLL as well as other manufacturer info.

If you don't have gunnebo crane hooks you are missing out. On our brush picks we normally use one round sling w/gunnebo hook as the main load bearing sling and two spliced Tenex slings in 20' lengths. We normally use more than one sling because it always comes off prettier, safer for the climber, and less shock for the crane.

Can someone tell me what is different about the rope tuefuelburger uses in their crane slings in comparison to say stable braid. I am not opposed to spending the money on the tuef slings just curious the difference in those and just buying a 3/4" or 5/8" dead eye sling made from stable braid the same length. Please educate me folks.

I have been running this for spider legs and not sure what the Teuf. composition is even after reading the contents of the Chisolm rigging kit on Treestuff. I think (know) double/stable braids have significantly lower working load ratings than these and the larger (dia) the line the more difficult it is to secure (knot). The key is not having slack in the legs and with a fixed round sling/s and even putting in marls to take away the slack is it is time consuming and not as easy to de slack as just a single line leg.
I have been considering for years getting some medium sized porties made of aluminum fabbed to lash to the stabilizing stems and that way easily take up slack and secure the legs, but never got around to it but that doesn't mean I won't do it.

I've been trying to do some research and figure out the MBS and safety factor of WLL of the Chisolm crane slings. Treestuff lists the WLL as 8,400lbs for a choker. Is that a 5:1 safety margin? By "choker", does that mean just tying of the working end with a cow hitch or some similar hitch to the pick? Anybody have pictures of the tags on these slings?
