What is the German term for 'pylon'?

The German term for 'pylon' is indeed "Lastenträger." This term literally translates to ‘load carrier’ and is commonly used in engineering contexts to refer to large supporting structures that bear loads, similar to the function of pylons. Pylons are typically seen in applications such as bridges, power lines, and towers, where they support significant weight and provide stability.

The other options do not accurately represent the term 'pylon' in their meanings or uses. For example, "Rohr" means 'pipe,' which relates to cylindrical tubes used for fluid transport but has no connection to the structural implications of a pylon. "Vorsichtsmaßnahme" translates to 'precautionary measure,' and while it pertains to safety, it does not relate to structural elements. Lastly, "Felge" refers to a 'rim,' typically associated with wheels and tires rather than the supporting significance of a pylon. Therefore, "Lastenträger" is clearly the most contextually appropriate choice for the term 'pylon.'
