There is also a lot of expertise that can be found in crane work. I have my little corner of experience at the part of it that I can do, am still learning, but fortunate to get the chance to frequently work with some very highly skilled people at it. In our main crew of four guys, I am the...
i was pretty furious inside at a crane operator that i thought dropped the pick a good foot or more after immediately after removing a top. Kind of off to the side, but it would have creamed my leg a couple inches more in my direction. Later, I asked the ground guy that was positioning the...
So, slippage would normally be more prevalent during the drier season? That would be our winter.
I watched a couple older guys doing crane removals near my shop. I know the resident, and i kind of ran by him why he didn't at least ask me for an estimate? "These guys are cheap", was his...
On lighter picks we normally use two same length cables with locking snaps. They both get wrapped around, normally twice at the same point, unless needing to balance the load. With the two cables there is some divergence of bite into the wood .
Slippage on bark when making the lift can be a potentially very hazardous occurrence when there are no limbs to bind around. Since we only use wire rope chokers, and limited experience with slings, which would have the better anti-slip tendency? With wire rope, slipping is not all that common...
Good point about tying off. There was some discussion here quite awhile ago about securing a crane pick with a rope when cutting at the base, given some potential damage to something in close proximity. Some folks didn't think it ever necessary. We certainly will tie off if there is any...
Talking about one tree is a completely different situation from doing a number of them at the same location, with the crane sitting in the same spot, when comparing climbing or riding the hook for efficiency. One tree is quite a bit less frequent for us, so that is a big point of delineation...
Mostly doing conifers exactly the way Squish describes. if you don't ride the hook to tie off, how are you going to do it? I mean efficiently without having some sort of lift or climbing? Three or four minutes up and down without wind or crown complications, the only consideration is keeping...
Pretty casual is often the case, depends on what your procedures are..how much wood is coming down, and whether it is getting cut up and cleared out before the next load. With more than one person on the ground, it shouldn't be a rush, I suspect.
Sometimes the people on the ground can help with communications between the climber and operator.
Ground guys often have free time on crane jobs. Don't fall asleep!
