porta-wrap tensioner

Gday lads does anyone have a picture of a porta-wrap tensioner?

thanks cheers!

This is what I use for tensioning a large porty.
Compliments of Reg Coates. Works like a charm! I don't have any pics of it in use.

thanks lads but not what im looking for what im talking about is made with rope bieners and pulleys basically like a 3:1 to tension the rope into your porta-wrap

All sorts of MA systems here:

Tackles

Choose how much MA you want, how much length you can use and then use the gear that you have at hand.

Is this for a piggy back MA or in-line? Reg's unit is an example of a piggyback.

we can always count on you eh tom thanks

This is a lightweight 4:1 MA rig I made for tensioning ziplines. In the video I'm using it to lift a broken limb clear of a house service line. It's built with 2 CMI RP110D Micro Double Rescue Pulleys (7000 lb.) 8mm static cord, a prusik to grab the rigging rope and a Cinch to capture progress and release load when I transfer to the portawrap. I think you can see how it's put together in the video, if you want more details I'll snap a photo of it.

I have been using a porty to pull trees over.

I take out my pintel hitch and put a double braid spliced end lanyard in the receiver and anchor it with the hitch pin, then bolen it on the porty and take plenty of wraps and a couple of locks on the ears. Makes for an easy attachment midline for the pullover line without any knots. Just pull the truck forward for the Yankovich and then take the rope easily off the porty with no knot damage.

I also have snapped a porty on the end of the pull cable on a come a long and do the same attachment after lanyarding the come a long and porty to the base of the anchor tree.(when I cannot get a truck to the location).

For lowering (and lifting first) this also could be done if you lanyarded the come a long to the base of the tree and extended the wire rope of the come along up with the porty snapped on the cable end and attach the lowering line to it.

You would need a ladder or climber to tie in to attach the porty up there, but maybe not by the time you lifted the branch you were trying to lift (as it is coming down to you). Then you can lower if it (theoretically) swings away from (wires?) by taking off the locks and wraps.

All these hook ups can be manually tensioned by hand prior to mechanically or truck tensioning so you eliminate slack. I use the 2 big portys mostly,and use the mini porty with micro line on small stuff.

I even used a porty on some tornado jobs last week to tie trees quickly together with 2 split co doms 2/3rd way up and after releasing some pressure....you can unwrap and get rid of the porty or re tension and re wrap.

We also put a running bolen around huge piles of brush and porty it on the mini to drag. You can get way more than if you used a grapple.

I adore portys

I have been using my portawrap in a similar way to pull over trees. I tie a tight bowline on one end of a short piece of 3/4" rigging rope and a long bowline on the other end. I girth hitch the long bowline to the porty and the short one pops over my hitch ball. This save a bunch of time trying to untie jammed knots in my rigging line.
