Where I am, they are often used to move farm equipmnt, but not on a trailer. They strap 2, 2000 lb concrete blocks to the frame over the axle, for traction, and then use them for moving pin hitch farm equipment. “A trains” are also not “semi” trailers, least the back one, and the triple trailers you see UPS and hay farmers use in the west half are full trailers.
Ah yeah, I only ever see full trailers in this configuration:
Not really common practice to hook them up to a conventional “tractor” (we call it a “saddle” truck here), usually they’re hooked up to the type of truck where there’s a fixes trailer as well (as seen on the picture)
Might just have something to do with length limitations in the EU compared to the US (it’s also why we have cabovers rather than the cool looking US trucks)
Canada, they allow 2 semi trailers hooked together, a “B-train”, B trains make much more sense, unlike A trains and your picture, they can be backed up easily (with a skilled operator) around a corner. I could manage backing up both those conveyances in your picture, but the bottom one would come fairly easy, the top one would take a fair bit of practise.
My picture is significantly shorter than a B-train. We have length limits here as streets are narrow and the trucks in the picture have roughly the same wheelbase as a normal tractor
True , forgot about that. Then again, how often do you see that type of truck pull anything other than a semi trailer? I don’t think I ever have
