The comic changed a bit, Hulk was more in a lifting position than in a bracing one but even in the original one I'm pretty sure Hulk was intended to have 150 Billion Tons on his shoulders.
Looking at the new comic, he could very well be carrying a lot more. It seems like he's supporting the entire thing in that one. The Andes is like 7000 km f*cking long, imagine supporting a mass larger than that.
And it was a base Banner Hulk.
Edit: I think the 150 Billion Ton figure was mentioned in the new comic.
