24akselisilla
24akselisilla is a term that appears to be a misspelling or a non-standard variation of "24 akselisilla" in Finnish. "Akselisilla" is the adessive plural form of "akseli," which translates to "axle" in English. Therefore, "24 akselisilla" literally means "with 24 axles."
This phrase would typically refer to a very large and specialized vehicle or a convoy of vehicles
