There might be someone here that can educate me with a couple of things
What rules are ballast lorrys running under i always thought stgo was non divisible loads but some of these flatbeds are running 6+axles plus the unit yet are a divisivle load
And how does it work with excavators as ive seen 30 and 40 tonne machines being moved with a full set of attatchments
Are they just seeing what they can get away with
Ballast truck and its "trailer" are not the "load"
STGO is a can of worms that causes arguments / heated discussion amongst the lads from different outfits that run them all the time so a layman has no chance of being 100% correct

my understanding, bearing in mind I've only ever hauled up to STGO 2 and never more than 1 machine at a time.
STGO 1 is up to 50t gross, normal haulage is 44t assuming axle configuration, plating and taxation.
STGO2 up to 80t gross.
STGO 3 up to 150t gross NOTE, there are minimum number of axles required, maximum axle loadings, and speed restrictions when operating within STGO
IF an item of plant puts you into an STGO category you can load a similar item going from same loading place to same delivery place provided it doesn't take you above the initial catergory and doesn't increase the width or length of the original load.
The question up for debate most often is that if an item can be moved within normal C & U regs then it should be, so how does 2 off 13t exc become a legal move on STGO?
I think you answered this in your initial question
