first time using slings to lower multiple branches

i used 6 nylon slings with a carabiner on each sling and then tied slip knots on my rigging line to clip the carabiners into. worked really good! i think im gonna use this method on plams next week! advice on honing in this system would be great. thanks
 
I too use that method as well and usually keep an assortment of nylon slings on my saddle when anticipating their use on a job like that.

Another method that I use especially on conifers where you don't have to worry about the line slipping is to just use half hitches in your lowering line wrapped around multiple branches. Very quick and secure too.
 
If you have a large rigging ring, you can also attach all of the carabiners to the ring at the the end of the rope. This is probably most functional on a conifer, allowing removal of each whorl at once. If you wanted to do multiple whorls with one lower, you could girth hitch additional rings on the rope, or prussic them on the rope.
 
Rather than lowering you can do that and make a light zipline too. The groundie can hold onto the rope and let the limbs slide...slacking the rope before the limbs skewer the belayer.

tie off the rope to the base of the tree and you have a vertical zipline.

cool i gotta try the zipline idea. my groundie deserves to get whacked after his spilled coffee in my truck yesterday.

You can let'em fly and they land with all the butts in the same direction.

If you need to, you can re-direct with a pulley allowing your groundman to be out of the line of fire, if he can keep his coffee to himself.

A mechanical advantage MA system can help to keep line tension appropriate. Beware dropping too much weight on too tight or horizontal of a zipline.

If you want to control the piece, you can lower it using a different line. If catching heavy pieces, catch with a lowering device and rigging line, then tension speedline/ zipline, and control it down. Dropping directly on the zipline has a force-magnified effect.

A vertical speedline is useful when you just need to keep it for getting away from the base of the tree, such as when there is an obstacle to the side or downhill of the tree.
 




This walnut leaned over keeper trees, so when the tops were out, we use a pseudo-vertical speedline to block down the wood. It was attached to the top and butt of the tree, sending blocks down on a 70-75 degree angle.

I strongly recommend the ground man be well clear of the speedline if you drop dog legged or oddly balanced pieces.

[/ QUOTE ] nah i want him to get hit. jk.

i have a petzle trolly lying around here somewhere. i was thinking of having my rope run from the ground or porta wrap where it then goes up to a block then attach the end that comes out of the block to the trolly where the slings are attached. on the tail end of the rope where my gound man would be holding the rope he can use a porta wrap to control the load. does that make sense?

Joshua, it would make your posts more easy to read and give you feedback on the complexities if you embrace the Shift key at the beening of sentences, and the Comma at the ends of clauses, please. It is good professional development for when you have to write for customers, etc. Thanks.
 
Punctuation police! What's next?

I'll be the spelling monitor.

Southsound, I think you meant "beginning," when you wrote, "beening." Or is that some new leetspeak I'm not aware of?

Grammar police here... Winch, you know better than to end a sentence with a preposition!
 
Not trying to be punctuation police. I tried to read it several times but gave up, hoping for a "translation". I do type too fast some times. Joshua has been asking many good questions about tree work, and seems eager to learn. I've learned tons from tree forums. If it is easier to read, its easier to respond. That's all.
 
Sorta along the same idea of maximizing lowering potential... self-lowering can increase productivity, allowing ground crew to do more processing.

I worked alone the last two days. I was natural crotch rigging for friction and easy. After landing a piece, I attached the next midline, and lowered another, and another, and another, then went to the ground to clean up and clear the line.

Today, I was speedlining by setting a pulley high, with the ground end anchored to my truck hitch. When I attached a limb, I cranked down on the speedline to tighten and wrapped it on a stub, then cut, and pulled my end to tighten even more in order to clear a garden. I could then unwrap the stub/ anchor point and set the next one and repeat. After I got a bunch on the ground, I went down and processed. Then re-ascended.

I watched everything extra carefully since I was solo. I'm not encouraging people to work alone, but it was what I needed to do to get the jobs accomplished.

or without some of the punctuation...

Also, did a bunch Double Whip Tackle DWT-style lowering, both with slings and natural crotch on the piece being lowered.

There was at least one good thread about self-lowering with different DWT-style techniques, but I didn't see anything about using natural crotches on the limb being lowered.

I think that this was before I saw Joshua appear on the Buzz, so its just a heads up to increased efficiency for the crew, as applicable to the job and staffing.

It can allow two people to work two trees simultaneously for simple canopy raises, etc rather than one climber/ one groundie/ one tree at a time.

What is "leetspeak"?
