Re: 500-ish ton mobile crane
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.
