What is the meaning of the term 'pulley' in German?

The term 'pulley' translates to 'Flaschenzug' in German, which specifically refers to the mechanical device used to lift or move materials by changing the direction of force through a wheel over which a rope or cable runs. This device is common in various applications, such as cranes, elevators, and theater rigging, where it is essential for reducing the effort needed to lift heavy objects.

The other terms presented do not relate to 'pulley' in a mechanical context. 'Blown' generally denotes something that has been inflated or is in the act of being blown, 'Kabinendach' refers to a cabin roof, and 'Kohlenstoff' translates to 'carbon.' Therefore, the choice aligning with the definition of a pulley is clearly 'Flaschenzug.'
