Only had to use an A-Frame support twice in over 40 years of tree work, but works great when needed. I have some pretty good diagrams of all the loads calculated, when I last used it, which I'll try and upload.
How many of you newer guys have had a chance to do this?
BTW, for those of you who...
I have a motto that I live by..."Fatigue makes idiots out of all of house."
A 13 hour tree day is way too long for this type of work, better and safer to come back the next day.
Though I think I deserve more than a participating member under my name since I have been on TreeBuzz for 20 years and I'm one of the first 400 members.
Great info Patrick! The use of a trucker's hitch aka Z-Rig I feel is one thing that a lot of new tree guys don't even know about in this age of technology, and if they know about it, then they don't know the mechanics behind it.
Nerdy stuff to some, but to hardcore rigging enthusiasts like me...
All good advice, but as someone stated above, if you're not a member of TCIA, become one. They, more than anyone here knows how to deal with OSHA directly, as they deal with the Feds daily and can tell you exactly what to expect and what you need when a visit eventually happens, which it will...
After searching for over 10 years, I was finally able to find a 1" Hobbs Block (thanks again Lawrence Schultz). Really is a piece of history. Showed it to Don Blair and he says that it looks like one of the earliest Ed Hobbs block designs.
Yup, the Hobbs socket mod is THE WAY to go with the H2, makes all the difference in the world!
I'll get some pics up on the way that I modified mine, as it's a little different than flushcut's.
Hey Phil, sorry for the late reply. I haven't had time to be on TB lately.
To snub the main haul line, I just had an employee at the back spar tethering the line with a large Portawrap. We were lifting loads about 20' into the air, give or take. There wasn't any drag on the material until we...
Good eye Phill. Yes, my control line should have been shown in that picture. I was under the gun to get photos in to TCIA and had to do a mock setup of an English Reeve system at my house. You would want to have a control line/s that would allow you move the carriage back and forth.
Will have...
Nice work, we'll check them out. Thanks.
Looks like you're floating wood in the pic with a tip and butt tie. We do this all the time with polyester double-braid lines as well without any issues. Much more favorable rope angles with this technique. As you probably know, floating wood with a...
First, I just want to thank Tom D. again for posting another one of my articles, I really appreciate it!
In regard to using the ArborPlex, obviously this would not be my first "go to" line when setting up a highline, but it was what we had for the long span required. I would love to have a...
