This photo is from Wikipedia. From its name I learn that the German word for wheelbarrow is "schubkarre." My first thought is "schlep" and "cart." I await the clarification of a German. (I'll try to remember to send a link to Wolfgang Marquardt or Sabine Reichelt after this post is out.)
That wheelbarrow is in an open-air museum in Germany. The image lives here and is linked on wikipedia's Wheelbarrow page.
Deutsch: Schubkarre im Freilichtmuseum Neuhausen ob Eck
English: Wheelbarrow at the Freilichtmuseum Neuhausen ob Eck
