New company uses a crane often only problem is the climber just throws his lifeline and lanyard over the hook and off he goes. Now i know thats not how its supposed to be done so im looking for a pic of a better way.
Need a picture of the Correct setup for crane tip

Rope over hook, hook up, let rope run through prussick/shunt till level with where you want to be, let go of prussick/shunt, wrap legs around chains to stop em flappin, enjoy the ride..............and don't get caught.
Can't find close up pic of set up, heres one using crane as high point

Ok....well.....here is what I believe to be the approved and safest way......
Use a small shackle and slide it through the loop end on a single loop friction saver that is long enough to hang to the bottom of the ball. You then tie into the ring on the friction saver. The set up is mounted, as I said, above the ball..... So that way you have double safety, as you are attached to the cable, just like the ball is.
Here is a link with the standard as well as a few pictures: PDF format:

Friction saver and locking shackle above the ball, never in the hook with slings and chain. Keep your climbing line seperate and protected from eveything abrasive, anything that can pinch or bind it, and off the hook.

Yup, your climb line over the ball and your lanyard on the hook.

We agree! I had occasion (all too rare) to bring in a crane and tied in above the ball with a heavy steel 'biner and put my flipline through the hook.
The crane operator had never seen that and objected, murmuring "OSHA" of some sort. I showed him how I could loop the flipline up and off the hook through the gate and got no more objections.

Pete Nails It!
The shackle in the hook prevents "loop out" of your line as well. Great rigging there Pinnacle Pete!
An additional benefit of tying in above the ball is more maneuvering room around the load. A higher tie in is always better.

Looks good to me! This is the only way that I know of that is ANSI approved...

This is a much safer way to attach then using a friction saver
I don't know jack about crane work really, but that looks like something I could work with!
I assume you had to dismantle the ball (or whatever it's called) to get that link in there? Nice.

Nah ya just knock the pin out of that thingy and it falls out of the big round thingy takes ten minutes lol ya know what I mean .....That thingy ...

Much safer? I don't think so. As depicted in Pete's image, the friction saver provides the same level of protection as using it in a tree. Keeping the rope off the ball "thingy" is the goal and both methods depicted accomplish that.
Me Culpa on using a steel 'biner on the cable above the ball in my example, as my rope still ran across the ball which should be avoided.
"Wayne the Crane" didn't have the clevis i would have preferred to use, so I had to make do.

Wow you got to use a crane for that weed leaning on the house.....Damn son ya coulda just spiked up the downspout and tied into the gutter
Hey is that an OSHA approved baseball hat.......Aerial Arborist I am surprised at you....How are the children gonna learn good PPE habbits with you as an example

Nice hat.... I am sure Wayne is really happy about u posting info about such poor practices.
For starters an aluminum friction saver has no place anywhere near the almost 300lb ball.
What keeps the fs from falling off the shackle when the climber pulls his line free.
I am responding from my phone, I don't have the time right now to explain all the things wrong with that system right now

Steel rings on the friction save and steel biner on the shackle captures the FS. As you know steel and aluminum don't play well together.

The picture that was posted was off an all aluminum set up, norm from the" other site" posted that a while ago.
I wouldn't use that setup, I am guessing I have a very different view point on this then most here. We do crane work everyday, doing it every day of the week year after year you see things happen that u didn't ever think could. Light duty Arborist hardware has no place on the ball of a crane.
I am not saying we are the only ones who do crane work, I know of a dozen or so companies in our area who run "production" crane removal crews, have seen a bunch of different ways to tie into the crane, some I have liked some I haven't but none as bad as the fs method.
its very important that everyone understands that none of these methods are ansi or OSHA "approved"... the fs method and the method I posted both satisfy (to my understanding and interpretation) the ANSI 133 standards. Until there is a OSHA manual that has a description and diagram of a method to "ride the ball" there is nothing approved about it. OSHA decides on a case by case how much (if any) recognition of the ansi standards they want to give, especially any of the ansi standards that are in disagreement with OSHA rules. We just have to do our best to meet OSHA general duty clause and protect our employees from all known hazards..
the method I posted has" survived" two onside OSHA inspections that I know of, but that doesn't mean if I get inspected tomorrow they might decide they hate it and start writhing fines, its the same with the fs method, it has allegedly survived an inspection also.

- Realized I need a little clarification in this statement. It was the secure connection above the ball that I was talking about being ANSI approved. Method of connection is up the the climber and crane op to work out and will be approved/disapproved on a case by case basis. We personally do the large friction saver through the shackle, and here in CA CAL-OSHA requires another connection through the hook and that the hook have a gate on it.
Remember that just because your doing it to federal OSHA standards, the state your in might have more restrictions placed on you...

thanks for all the responses guys from the looks of it i like marquis method the best so far, although the other picture posted was alright too maybe one could girth hitch the fs to the shackle so it doesnt come off when climbing line is not through it, and def steel rings on the fs, marquis what size shackle you got there in your picture and is that the set up you ride everyday?
And just to clarify marquis that is your climb line run right through the shackle correct? If so im wonder if i could steel biner a pulley to that if neccesary to reduce the friction and open the bend radius up a bit on that. And that ring above the ball can you enlighten me on that?
