Cranks hitting the rear triangle/frame?

Hi,

I recently bought new cranks and a new bottom bracket for my MTB.

The only problem is that the cranks hit the frame when I pedal hard.

Unfortunately, I don't know the exact name of the frame.

These are the cranks:

And this is the bottom bracket:

I haven't tried any spacers or anything like that yet.

Thanks for all answers in advance.
