I get what your saying Royce. I would add that the LMI doesn't make the current pick safer. Once you cut it, you own it. The LMI helps you to fine tune your weight "guess" for the next pick.

Yes, you get me!! That is what I was trying to say. Your correct, once the piece is cut you own it.

I understand you completely Royce. Used it friday for the first time. It was interesting working with such a small crane. Kinda freaks me out a little bit. Strange having to adjust the cuts because the ball is next to the load instead of above it. It was pretty much guess work on the weights. One pic was pretty much at the max and he had to bounce the base section across the yard to the log truck. Alarms screaming the whole time. I would have loved to have know what the actual weight was. Gonna take a while for me to get used to this.

That is kinda scary. Sometimes the alarm will go off when your trying to bounce the final log pick close to your truck. I hate doing that. I would rather take it in two. You will get used to it though.

Just be careful man. I want to see you posting in this forum from day to day. Whenever I do crane work, and I'm cutting, I do all initial cutting at shoulder level. Then the last bit of cut I spike down the spar a bit so I'm clear before I give the pick to the op. Sounds like it may be good practice for you with this guy.

I'm relatively new to crane operating but our standard approach is to make a few test picks to get a gauge for the density of the tree, check the lmi readout and adjust from there. I would also add that I don't trust my lmi to be accurate, luckily I think it over reads. The bottom line is it is all guess work, you just get better at guessing .
Steve you are a capable and cautious climber I'm sure it will work out.

Understanding the load chart of a crane is the most critical point of knowledge needed to work with cranes in my opinion.

Remove the "in my opinion" from that statement.

First full day of crane work. 4 jobs. Did 5 full trees not just poles like the last crane day. Man that little crane is pretty awesome when it's rite up to the tree. Sure can take more than its looks. Even with the jib.

Nice counter weight haha. We have a 3k pound chunk of steel that sits on our 15t. Picking 2 thousand pounds sure beats roping that over a house! Small cranes go places you would never think about putting a monster
