The world’s largest screen cleaning machine – in LEGO dimensions! Big engineering, recreated with tiny bricks! Our Erhard Muhr GmbH Trash Rack Cleaning Machine has been brought to life as a fully functional brick-built model. Just like the original, it moves along LEGO rails, rotates, moves its arms and extends its telescopic boom – all fully automated. The model is displayed on a custom-designed stand featuring an illustration of the submerged intake screens at the Muskrat Falls hydroelectric facility in Canada, where our original machine is in operation. 📍 𝗩𝗶𝘀𝗶𝘁 𝘂𝘀 𝗮𝘁 𝗛𝘆𝗱𝗿𝗼 𝟮𝟬𝟮𝟲 𝗶𝗻 𝗕𝗼𝗹𝗼𝗴𝗻𝗮, 𝗕𝗼𝗼𝘁𝗵 𝟬𝟳𝟳, to see our miniature version in action and discover the engineering behind the world’s largest screen cleaning machine! A big thank you to Alexander Ludewig for bringing this extraordinary project to life. # National Hydropower Association
