Brushing out a big pine

I actually find it much easier to estimate brush and tops the large crotch wood. Anyone else notice that crotch wood seems to be much heavier than normal straight wood?

Cuz it is...lots of layers in there...notice when you lay down a piece that is full of knots on one end and clear on the other where you have to strap it with one choker to balance it. I.e. full of knots = go smaller.
 
It's all about the grain. Straight wood grows faster then anything with any sort of twisty grain. Look at the size of the growth rings to compare. The tighter the grain, the denser and heavier the wood is.
 
At the job site Monday morning. Here are the yard pics and drop zone (or not). Considering using our 26-ton as a secondary rigging point to set a drift line for brush. Maybe a speed line over the street, but ground anchor points are poor. More pics later.

image.webp image.webp So far so good. We have the small crane working at nearly max reach and picking limbs 2-3 at a time. It's kinda slow but working well. A bit dicey picking larger limbs at low capacity. But it's not my show. I'm just pounding the ground today.

Now transitioning to rigging and speed lines for the side and back limbs.

A pretty good day. 60% of the brush out and chipped. The easy part is done.

I'm still skeptical about the "big cranes won't pick brush in Seattle" answer. I heard mixed answers in that from crew members. We will see what happens.
 
Nice job so far! Only if you had a few more feet on that boom eh ! there was a video of a big elm
Someone posted a few years ago where's that crane co? Looked like easy pickings for a bigger crane if only there was a co willing to do brush ( still a weird concept to me not too!!!) is what it is though.

Ok. The tree is now brushed out. Lots of rigging and then transferring the load to the 26-ton crane. Gotta give credit. It worked pretty smoothly. The crew was great. Tomorrow picking the wood with a 175-ton. That'll be plenty big.

Ps. The stem was measured at 52". Dang. One of the biggest Austrian/Black Pines any of us has ever seen.
 
It'd be fun to try one pick, but it's still a little too big for that. At the end of the day, I lowered off my tie in at 95 ft and I was a few feet below the top. Then there's the weight issue. We've got around 50' to the main crotch. There was no listing for Black Pine on the long weight chart I used, but Ponderosa is listed at 678 lbs/ft at 52" diameter.

So, if we assume an average of 42" diam. to the first crotch, and it's 50', that gives us just over 22,000 lbs not including added wood density of that crotch. My guess is we have a total of 45-50,000 lbs of wood to pick at a radius of 95+ ft. Probably not gonna be one pick, but I'll ask. LOL
