You can always apply scaling to a part or assembly if you want visual accuracy, such as for rendering.
Thanks for your advice!!
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.
