Loading 336F Excavator?

It's been a while since I had to load an excavator, where I had to worry about weight distribution. Where is the COG? Is it the cab, or center of rotation?

Thanks guys.

 

All I know, it's a new one from CAT PDC Tacoma.That's what I figured, but it never hurts to ask. thanks.

 

My dispatch says Cat PDC. Google says Northwest Container Services, it's on the corner of 509 and Taylor Way. the guy answering the phone just says, Hello. one of those you'll get all the info once you get there. .lol would be nice if they have a scale. Loves right here is tight getting off the scale

 

7 axle. Coronado with a trail king. It's a typical ATS truck and trailer.

 

It's been years since I loaded an excavator. When I was hauling construction equipment it was local in texas and we didn't worry about legal weight distribution. I was doing oil field for a while, then mostly pre fab stuff like buildings and tanks, ac units, ect.

 

It's dispatched at 84k, but add 10% to that right. I learned that on here. .lol
