Lets get this party started...

Looks like fun....


When i first saw the porty the green hose looked like it was part of the porty...

Speakin of which... is the rope set on it right? It doesnt appear to be, shoulnt the tail be commin out where the rope is commin in? I would think so, but i have only used the porty III, but it doesnt look right to me.

I'm confused what you're meaning?

Shouldnt A be wrapped starting at B? Shouldnt it be against the "major axis" of the porty at position B?

 

[TreeJunkie]

Honestly i couldn't tell you for sure, to my knowledge this is how we commonly use this piece, keep in mind we're not rigging anything to heave on this either. Does anyone else have one of these dinosaur portys?

 

[Lumberjack]

The only way i have read and seen using them is through the middle, and out the side. That way it loads the main axis with the weight without leveraging against the leg of the porty.





Eric: Did you knowt that the company you used for the crane has a new 365 ton crane with 197' main boom, and a 200' jib.... That is on helluava crane, and its all terrain at that!! Well whatever ground will hold it up!

Man what a crane!

It could do General Sherman... BTW what is the shermans estamated weight?

 

[TreeJunkie]

Wow! thats one hell of a crane...Bet they don't use that on trees often...But hey wouldn't that be nice, The one cut removal...

 

[NeTree]

Sure... it's only $20,000 a day!












j/k.. bet it's expensive, though!

 

[John Paul Sanborn]

Brandon, why no GRCS on that tree? could a done it way faster with The Winch!

And Joe paid good money for that thing!

Or is that reserved for only one crew

I like the old style portys but you can't block down a spar cause the line can jump off the wraps when the line slacks...
I wouldn't expect to see a porty and a hobbs on the same tree...
Also the way I was taught is to take the line around behind the center post of the porty, then take the wraps on the side bar.

Lord I thought that noone was gonna give a reply to it... Anyone disagree with me? I think that it would be akin to cross loading a biner, makeing undue stress on the porty.

 

[Lumberjack]

Here is a page that spidy posted. It shows the porty being wraped like tree junkie's is, but it is a drawing. I still think that startin at the middle is better.

I gotta hear what all yall gotta say about the advantages of porty over the good ole bulletproof wrap on tree. thanks in advance, i searched everywhere, did I forget something?

 

[murphy4trees]

The reason there is no discussion about that is cause wraps on the trunk are so far out of our consciousness.... If you asked a welder what are the advantages of an accetalene torch over flint and steel, he'd look at you like you were crazy.. I haven't seen a wrap on a trunk in recent memory....

 

[MasterBlaster]

The Porty is great, but I work with guys all the time that don't even use it. I prefer to use it.

There are several...

Wraps on a tree are inconsistant on how much friction they offer from tree to tree. Wraps are hard to lock off. Wraps candy stripe the trees. Wraps are hard on the ropes, grind grit into the ropes.

Porty does none of thos things and it looks more professional. Plus it offers more uses, you can use it on your truck as a "mechanical fuse".

Wraps are out for good, portys are ok....






GRCS is the stuff!!!! Need to get a couple

 

[Lumberjack]

Takin down a limb. Its goin over the house, and the guy is gettin a new roof, and he doesnt want it there. Anyway here it is.

Takin off the prusik off the main load line.

Look at that handsome fella.... and that PPE.... and that DdRT... man what a killer!

 

[Lumberjack]

The piece was tip tied and butt tied.

The tip tie was runnin through a false crotch, while the butt was a natural crotch...

The tree wasnt damaged by the natural crotch, as the limb that took the initial force/friction, and the top limb had the wraps, but it left no trace.

 

[Lumberjack]

Party on!!! I gotta get some pics on the tips, like Big John... They are commin.

wraps have their place. I don't see the point in setting up a porty if it's only needed once. A wrap on the tree is fairly idiot proof, easy enough to see if the groundies have it right from up in the tree. Tree wraps also aren't bothered by knots, on the rare occasion when the line isn't long enough. In many cases, a wrap is easier on the rope than a porty, much wider bend radius and greater dispersion of friction. It takes a lot to wear a rope enough that it needs to be retired before the usual prudent time period.

not that i'm knocking a porty's usefulness, i just think it's silly to never use a technique for no better reason than it's 'old school.' IMHO
