Really big machine!

This is a mobile log crane on RXR type tracks at Simpson Lumber in Tacoma, Washington.
If you look just below the shack on the top of the machine on the right side you can see a port-a-pot on the stair landing ,gives some perspective to the size of this thing.
I'd guess it's at least 75 feet tall and over 300 feet long.
