every used two portys on one tree?

Re: every used to portys on one tree?

i have been looking for proper instruction on the clock hitch to make sure i'm tying it right. does anyone have a link?
 
I have used two portys several times. The simplest way I've found is to run a 3/4" rope around the trunk three or four times and secure the ends. Then use two shackles to secure the portys to the rope, preferably on different legs, so as to eliminate them running together. If the rope is snug to the trunk, the porty won't move upward much at all because it will choke the trunk with the other wraps. Another advantage is that the porty can be moved around the tree somewhat to acheive better angles. If no shackles are available, simply run the rope through the porty, take a wrap or two and then go throught the other porty before tying off. With a really heavy piece, (750# - 1000#), the porty might run up a bit, but with moderate-sized pieces, it won't move far.
 
Dont ya wish ya had the duel stein?
I hope this was helpful

ya know i forgot to tell you all how it went. we used the large porty on the main trunk and then attached a figure 8to the trucks hitch back up bu a prussk. the butt of the branch had out 5/8 line attached to the large porty and a 1/2 line tied to the tip of the branch. after cutting the branch i had my ground guy lower the butt end to where he could pull it out of the way then my uncle lowered the tip with the prussik on the F8.

dang i really wish i could afford the stein duel but that doesn't matter anymore because now im am now an employee with treecareinc :)

Jeff,

just curious, why would you want to use the clock hitch?

is there any real need for it?

Here ya go.
Notice, both slings are anchored so when they are loaded, they pull against the bight of the hitch.
Bottom sling is anchored with a cow hitch.
Top sling is anchored with a timber hitch with 2 turns at the throat. If a timber hitch is used, 2 turns at the throat secures the hitch better.
The log in the foreground was lowered with the 2 porty's, tip tie/butt tie.

why use porty wraps (two) with all those wraps instead of a larger lowering device (or two if you need two) like a hobbs or grcs with drum?

I guess unless your company can't afford them, then that is understandable of course.

looks like some decent size wood in that ash picture Norm.

Is that why portys are used so much? because not everyone has the larger LD's? Or they don't like carrying them to the tree?
 
Re: every used to portys on one tree?

We just finished a job today using two Portys’s to drift some big wood out of a large red maple! I have to say I like using that new stein 1000 that replaced one of my old porty’s that fell out of the truck 2 months ago.
 
Re: every used to portys on one tree?

I'm using the Stein rc2000 and it's really nice. There's a learning curve to setting it up and tuning it. I set it up and tore it down several times to learn how to do it quickly. I have a large Whoopie sling with a sleeve at the anchoring eye and I notice that you must really deliberately set the girth hitch on the attatching beckett on the LD. Otherwise there is a definate friction hazard with the running line when it's loaded. I already glazed the sleeve once so I now inspect it every time I lower.

"clock hitch"

Oh yeah , trying to be funny . Clock hitch , think about why it won’t work for two porty’s . Clock hitch is a directional hitch for the porty , when you play "no wood on rope” , two portys would pull the hitch up the trunk , if you had Balls to cut a heavy piece . Just saying . A clock hitch would be the best App. for the second porty because it would be more directional . Or a whoppie sling , that is easy to adjust to be inline. A timber and stillson are fixed . I use two all the time . The second Porty is mostly used for a Butt line and that is not always inline with the main lowering line .
 
Re: every used to portys on one tree?

Actually I use the clock hitch ever since that thread a few years back, only in some situations. Never tried it with two portys, I guess if they were pulling from opposite sides it would pull the hitch up the trunk, what about from the same side of the tree?

Company was too cheap to spend money on a GRCS or Hobbs. The tree crew manager was a landscaper with no tree care experience. It was a nitemare trying to convince a landscaper that lifting devices were time savers and injury savers. They had workmans comp cases up the wazoo.
That job was a learning experience for the rigger and ground crew. They had never used 2 pulleys and 2 portys to lower 1 log. It was a decent sized log to lower for them.
