No idea what it is called in English. Dad calls it “Umschlaggerät”. Figured I’d share before he sells it

Couldn’t find a Wikipedia entry or anything, but it is basically a trailer that gets placed at a construction side. You then raise the wheels, so it sits flat on the ground. After that you unfold the ramps and now a dump truck can unload sand, gravel, or concrete into it.

You’d then use the built in hydraulics to raise the hopper into a vertical position. Now you can fill crane buckets, skidsteer shovels, or even wheelbarrows at your leisure. Before concrete pumps were too common they were often used as reservoirs to fill a crane’s concrete bucket.

Afaik in Switzerland it is now illegal to use them for concrete, but when my dad regularly had small construction jobs he used it to store gravel. Having one full dump truck delivering gravel to us was cheaper than having them deliver a couple hundred kgs to various clients.
