Pix of your crane tie in method

[ QUOTE ]


that retention pin gets caught on a twig it could easily come out and not be noticed. Things could get ugly fast.

The nut on the other side of the pin would then have to be unscrewed.
 
you're right...did not notice the nut. Think a cotter pin would be safer nonetheless. It is bound on both sides.

That is the exact same headache ball I have.
 
Hey thanks for the comments, I have used cotter pins before but I am comfortable with this setup and I inspect it including making sure the nut is tight, before I tie in every time it comes back to me. I also trust my crane op. a lot he has he has communicated to me many times that he wanted me to double check it when he saw it brush through some limbs and such.
I am still wondering if anyone has heard of a new standard that forbids tiying into the load line. Thx
 
Had to bring in my friend Roy at Arrow Crane today to pick one over the house on the roof as my crane is not capable of dealing with steep driveway with sharp turns (backwards).

Here is the set up he fabbed. They cannot run off the load line like we can.

I am running a clevis and am going to set up a large D link a friend from TB sent me when I get around to putting it on. Eventually tho we will prob have to go with a set up like this and stay off the load line.

I really like the way that set up looks( except the pin needs to be caged). If I were still on that type of crane I would prefer that over the shackle on the weight set up.

Where did he get the set up. Is there any ratings on it. What is its original use ? Sorry for all the questions

Re. Allmark

He invented and fabricated it. He had it inspected and rated to spec. as far as ANSI standards for crane ops. It has a rating on the side of it. It was made to carry a climber as he does a lot of tree work. They are one of only 2 upper echelon highly experienced tree/crane removal co.s in Cinci, The other being Decker Crane. I go way back with both of them. Guessing maybe 30 years. There is a third co. I used to get to do tree work with from around 1980 called Fenton Crane, I taught them after moving out here from NJ, but think after so many half as sed tree guys they suffered thru over the years, they gave it up.

I believe I am the first one he ever carried. That crane, an 18 tonner, was the one that fit into that job. We, Jack and Roy and I (Arrow Crane), have done some amazing tree jobs with that size crane. It is nothing like an 18 ton truck crane. I believe he has maybe 8 to 10 cranes.
 
I'll tell him you like it.

Anybody try a Rope Wrench off their crane set up yet? Seems like it would be a good ap. I have a rw but have not tried it on the crane yet.

Treevet, WHat about your climb line rubbing on the ball as it slides past it?

As long as you look at the ball and there are no burrs it shouldn't be an issue

Have thought the same thing, but haven't tried A wrench crane setup yet. How would you anchor the line through the rings/shackle so the system can be retrieved, untied then re-tied in the tree? My only thoughts for now would be the jamming Ring n Ring trick. Any thoughts?
