1:12 SL-400 Truck Crane

[scalecranes]

Well I guess I've made enough progress to start a build thread for this project.
First a little background on the 1:1:
The original belongs to the company that I work for and is a one of a kind. SL-400 stands for Street Legal 400 ton capacity. When it was completed in the early '90s it was the largest crane able to be moved around California without removing the upper works. It can self-erect with upto 185,000 lbs of counter weight and 280 ft of boom. The max counterweight is 210,000 lbs, but it requires an assist crane for this because the stack is too high for it to swing over. It also has a fixed jib that can be upto 90 ft long.
OK enough talking, here's a picture of the 1:1

And here are two pictures of the progress I've made on the 1:12 scale model. First the bottom, 2 main, and one of the two upper counter weights that make up the 185k stack. These will be filled with about 115 lbs of lead.

Here is the rear half of the carrier frame sitting on the outrigger boxes, with one of the outrigger beams in front.
