However, the collision is too much to be explained by the 0.5 LDU thickness difference.
According to the photo, the crane looks like "open jaw" slightly, the strain should be absorbed by rahmen structure of posts and beams.

Yes, certainly a combination of the two. The parts have considerable natural flexibility, and then the tiny gap between bricks allows an assembly to bend even a tiny bit more (though this is more pronounced in the horizontal direction).
Either way, scaling is the simplest way to visually correct for this—not that most modelers would or should bother, of course! Theoretically, you could also build accurately-sized parts and combine that with LDCad's flexible generator to hyper-realistically model this bending, but now we're just talking crazy.
