Speed line pulley

R

Rickytree

Just wondering about this as a pulley for a speedline setup. I got everything else.. 5 to 1, slings, porty, lots of rope, clips, Just wondering about anything else I'll need. Never did much just with a rope, a clip and sling over a service wire and a stink pile of wind. Want to rope out wood also. Any thoughts?

thinking of this one for the convenience of a haulback line and controlled descent. Plus you can't beat the price.
 
I've never tried it. I know you're not supposed to corner with a controlled slide line (lol) but I'd be cautious of the sharp edges on this thing. The haulback becket is sweet. My current ride is a plate with 2 Petzl Tandems linked into it but we're talking 5 parts versus 1. Dump the wood into a spar rig first man, THEN connect to your controlled slide line. You probably know that in which case Kristian will be shutting up now.
 
Here's my preferred Method. Just a pulley will not have enough weight when you haul it back. It will flip and twist the haul back line around the speedline and cause you headaches!

A rigging plate will work as well.

Ricky I own one of them among many other tandem pulleys, but never once have i used them on a speedline

I use those for people ziplines.

I've done quite a few speedlines and the more simple, the better imo.

Light to medium stuff; I just use loop runners with the smaller steel biners. Biners run down the rope. No rope glazing, no problems. No hauling back crap, at the end of all the runners, groundman sends the whole bundle back up. If a really long speedline and they are running fast with no control line, groundman needs to be careful they can be a little hot in that case.

heavy stuff use a large steel biner and multiple loop runners or else a heavy loop.

real heavy stuff, just use my large rigging blocks.

In my opinion, blocks are not needed unless you want to run it really fast or extremely heavy.

Here is one from last week. Diagram attached, real photos following.

Some limbs and logs heavy, so rigged them with bull line like usual, then tightened speedline to transfer them away from the tree.

OH! Word of caution. When blocking down a log and intending it to use speedlien, careful you do NOT attach speedline, (not even slacked i mean), IF you need the groundman to let that heavy log run for a while. Logs can spin and wrap up that slacked speedline, which stops the run, which equals yank you around.

sorry, most of it was video, so didn't have too many examples to show.

in this setup, since I had the speedline low in the tree (for a one spot point), we left the big steel biner and red loop sling attached.

groundpersons would just untie the sling on the lowered limb.

groundperson would pull the bull line back to me, it would still be connected to the speedline.

no pulley, no plate, no worrying about spinning it.

I am with david all the way. But..I use aluminum (GASP!!) biners, not even lockers, and the slings I use, I made a bunch of them out of old rockclimbing rope, with knots (GASP!!).

It works great though, never even had the slightest issue or hiccup. Climber pulls up 5 or 6 slings, makes a bunch of cuts, groundie takes the slings off and when I am out, they send em all up at once. It didnt cost me a thing either, cause I have dozens of non locking biners form my rock climbing days and the local gym gives us the old ropes.
 
Sound good.

Xman could you explain this pic for me. If you are cutting where you are the piece looks as if it would come back at you. Not knowing the surrounding area why was a rope loop put in the system and why there? Thanks just curious is all.
 
Ricky, I respect you more and more that you post.

You read the photo correctly.

I notched the limb, back cut it, then climbed up high out of the danger area, before a groundperson pulled on the speedline to initiate the limb to hinge.

well, almost climbed out of danger zone.

the peice hinged around faster than expected.

Even though I was high up, a few twigs came at me, groundperson should have switched up the plan and let it run a little at that point, but did not. I got a limb in the lip. No damage. Groundperson said he tried to switch up and let it run.

Now, why am I using a sling, amsteel blue for the limb tying?

the bull line that catches the load needs to be long enough to run down the speedline to the end.

after the first limb run, bull line was determined to be slightly short of proper drop zone.

so, I added our crane amsteel sling to add length to the system.

this gave just enough length to allow groundpersons enough slack to unhook stuff.

excellent questions.
 
For light to medium size stuff do you guys typically use 1/2" stable braid, or something more static? Would Amsteel be a good choice if I can mitigate abrasion?

for the speedline line itself?
 
Ricky, thank you for bringing up the cmi trolley pulley that you did. I forgot I had it.

today, i had a high line to remove a really rotten tree, I was going to use the gold petzel tandem pulleys I had, then your post reminded me I had that cmi with the haulback hole.

I decided the haulback would be good for grounperson to return me to the tree I started in.

Worked awesome.

BTW, I always thought that pulley was way smaller than you would expect. Advertising picture somehow makes it bigger.

here is the orignal item you asked about, in real life situation:

another up close.

BTW, you need to set up the haul back line like this, or the pulley will flip around.

bowline loop that captures the high line WITH the pulley hole. haul back line under the highline, with haulback line attachment UNDER the highline.

I am now going to review my video from today. Such a very fun day. Loved it! A nasty very decayed tree, ready to fall apart. So much fun setting up a safe system to work that nasty tree from. Can't think of the last day I had so much fun doing a tree removal. I hope the cameras captured it.
 
Nice work X! Has anyone tried using a high line with a Srt system rather than DDrt? or would this put to much force on the system?
