500-ish ton mobile crane

picked up some stock for the boom today and chopped up a cab







the main part of the boom is 3 x 1 1/2 tube 36inches long and is going to have 3 stages to it. i'm going to have to build some bad azz outriggers

If you have the counter weight correct your out riggers only need to support the total weight of the crane. It shouldn't tip. I saw a guy at a show last year who was retired from Grove and he built a truck crane like yours only a older model that has a lattice boom he built from Stitka Spruce. When he booms it up all the way and adds his jib,he has 21' of boom. Then he demonstrated the erection of a scale model cell phone tower.
