Rigging point

If you have a large round sling (continuous loop), and any pull-down/ retrieval rope, you can easily hang this. The bowline variation is good, just specialty. Round sling give the option of a super strong sling that can be use.

Would you tie off a rope and biner to the sling to act as the knot and line then?
 
Yes. It's effectively a girth-hitched sling holding the block.

The tied BL variant makes a round sling and installation/ retrieval line combined. That's all.

I like the simplicity of this it’s great. My only complaint is the bight comes right into the knot not the most ideal but as long as you keep it in mind for the load I think it’s a good answer. Thanks

It is an elegant solution. However, years ago we did a timed test. Setting a static retreviable as shown vs. just climbing up and doing it in tree to be retrieved from the ground.

Climbing won every time. Of course I was younger.

Tony, was this 'sprint' conditions or work-pace? What kind of climbing? Climbing line already in place?


I will do work from the ground, eating a sandwich and drinking coffee and water, watering a tree whenever need be, not risking falling out of a tree somehow, if I can fiddle with a fancy string and weight. Throwline skills/ use saves risk, wear and tear, and energy. Customers are impressed, too, which makes you the subject of conversations. Hanging whole trees instead of climbing them can save in many ways, too. $.02.

Southsound,
Standard SRS ascent, line not pre-installed. When we used this set up option the time vampire was getting the block over the limb and in an acceptable position. Trying to judge the size of the loop from the ground was hit or miss so we always had it too big and hence, the block was too far from the tree. It just worked better for us to ascend, set the system in the tree, then retrieve from the ground when done.

I agree why climb, if not necessary. To be fair we did not do this installation a lot. We used a 2 Ring dedicated to rigging far more. Currently I use a impact block and small rigging ring set up.

It is a fun way to set up a kids climb!

Ya...sometimes old school is just faster... Sometimes you hit the perfect high crotch on the first throw/shot... other times everyone stands around as you keep saying... just one more try

As a plus-sized climber, I LOVE remote settable/retrievable solutions and have used them quite a bit, but there's another aspect of how I have used these techniques in practice. Usually, I am trying to either use a rigging point that's away from obstacles including the stem of the tree. Sometimes, this is because there is no drop zone at all without the rigging point in the periphery of the crown, and I'm going to take smaller pieces into this drop zone: that is the situation where the remote settable anchors shine. In this case, I will frequently use a base tied pulley/block, accepting the limitations the mechanical disadvantage at the rigging point impose precisely because it is faster to install, remove, or redirect.

However, most of the time, I'm trying to take really large pieces, either because the drop zone created by the peripheral rigging point is so much larger and it will be more efficient, or because I have to take a large piece because of access issues or because of a large/tall obstacle like a building or another tree. In that situation, I am frequently using a lift and lower or pretension technique of some kind (GRCS, set of fours, etc). The large pieces and possible lifting means that a lot of the time, I am using a redirect or a backstay or both to back up the rigging point. Either or both of those can be retrieved remotely, but the are difficult (impossible?) to set remotely. Climbing either SRS or Wraptor makes setting these systems fast and easy, and opens the option to tie the piece off from the tree, which can also save time.

One recent example is a beech we removed on a pretty wicked slope. We used a large horizontal-ish lead on an oak at the top of the slope as a rigging point. I Wraptor-ed up the oak, MRSed out on the lead, backstayed it in such a way that it could be removed from my Wraptor anchor, installed a block that I could reach from my Wraptor anchor, installed the bull line, descended half way, installed a fair lead, and burned out. 30ish minutes from the first throw line shot. The other climber bombed that 80+' beech out in about 9 pieces, swinging up the hill, yarded'em out with the Avant & chipper winch, and then I Wraptor-ed back up and had the rigging system out in 20ish minutes. I could probably have done everything in the gin pole tree from the ground, but there's no way it would have taken less than an hour.
