It is a very simple pitchfork. It has a thick wooden handle and two iron prongs. It was used to load and unload bales, straw or hay. TIt is currently used very little. But where I am now, in the Vall Fosca, it also had another function. That is why it is exhibited at the Capdella Hydroelectric Museum, which I am visiting today.The funicular driver was touching the two electric cables of the line that ran parallel to the funicular track with both ends of the fork, and with this action he made a bell ring at the stations to to speak with the workers who operated it. This was the code: with one bell it indicated that the operator should stop it, with two bells, that he should go up, and with three, that he should go down.
