New guy crane questions

It is just girthed around the cable, above its termination clamp. That was @tc262 's treestuff tie in point. It is the safest and simplest way to get it done. And as a primarlary SRT climber, I still do DdRT off the ball, still can't figure a good SRT method on a crane with out leaving a climbing line attached all day.

I'm in the same SRT boat. So why do most people attach to a shackle instead of directly to the cable, or is this just my mistaken perception? My crane guy (haven't inspected his rig closely yet) said something about tying in to a carabiner that was attached to his shackle attached to the cable above the ball. I was thinking "no thanks" on the carabiner, if that's really the case, lol...

I'm pretty sure your required to have a shackle between the friction saver and load line, for ansi standards. If the crane would over lift his ball, he would potentially cut your friction saver. By having a shackle in there you prevent this from happening,cause the hard shackle would get hit not your saver.

Girth hitching the TIP directly to the load line is not a good practice. The load line has oil and potential wire picks which can damage the rope. The potential is also there to damage it during a 2 block situation(if this is a concern a different crane should be used).
Its simple enough to use a shackle in the system. Carabiners are not good attachment points to the load line due to side loading and damage to the gate from contact with the steel downhaul weight.

undoubtedly the first sane comment on this entire thread so far.
 
Hay Colb some of the climbers i work with pref one side of their body to the other because of more strength , and when working with a chainsaw body position is everything ! You know we would in a perfect world like to stand firm to cut but the tree dictates body position so use your strong side the most you can!

Hi folks,

I lost my first crane bid.

I now have my first crane work on the 17th - two small laurel oaks.

Working on my Ddrt climbing and just curious why an SRT tail on spar can't be the setup used for Ddrt on the ball. Anyone want to clue me in? I'm fairly sure I'm not the first person to wonder about this...

How are you planning on retrieving it? That is why ddrt is the go to for crane work.

Yeah, I know it's go to. If I have an 100 ft. line parsed to a 45 ft. tail and 55 ft. working line, I put an alpine butterfly-type mechanical connection on the tail side of the mid line and pull the line through and out after I'm in position for a cut. I understand there are details, but what is problematic with the overall idea of treating a crane ball like an srt spar?

Is it the length of the tail one has to pull?

I think so. The time that takes, and the time of resetting it to make your cuts and back onto the crane.
Seconds holding up the crane add time to the job. Ddrt doesn't take advantage of redirects or fast, easy ascent, but down is quite fine and nothing is faster than tossing your line around and clipping a biner.
 
I've srt'd the spar before but by the time you set your butterfly and retrieval tail, you can just wait for the ball to come back and tie back in. Sometimes I will set an srt line in another leader for work positioning or safety reasons, or just to be able to be in place for the next pic, if I'm feeling froggy.
Interesting about the shackle and friction saver combo. I guess that's why treestuff's setup girths thru the big ring. I used to climb off just a big shackle but recently went to a ring and ring with tritech and steel rings that I kleimheist just above the ball. The crane we primarily use can't pull the ball up to the point of cutting the cordage.

The only ddrt I do with crane work is riding they ball. Spar work is totally quick pulling the tail to reset position is super efficient for me and I use my rope to measure mill lengths. If it's a fatty I'll ddrt off the ball to reset or if I'm taking branches with the trunk sections. I do my absolute best to not leave stubs to catch the line on retrieval.
