Nostalgia de lo húmedo

We can see a solitary sand elevator. Its function is somewhat similar to drawing water from a well, which involves, through a traditional mechanism, lowering a bucket into the well and filling it before raising it back up. In the case of the sand elevator, sand is loaded into the object and lifted by chains to a surface with a mini slide with a wheel that turns as the sand descends. It falls back to the starting point and the process begins again.
