However, there are no images of krönbult and therefore the only person who can answer the question is probably the author.

crown bolt (bolt in crown/roof)

I've been using 'crown bolt' and got to explain it in a text ... the roof/ceiling is also called the crown (of the tunnel) and is 'krön' in Swe. My understanding is these are just rock (or anchor) bolts placed in the tunnel crown. But that is an 'armchair' conclusion. My customer, who has been kind of picky about things, has accepted this.
