These tensioners function by using a large, cylindrical weight hanging from a rope which is fixed to the larger diameter on that big pulley. The smaller diameter has another rope wound around it - giving a huge mechanical advantage. A little big of weight gets a lot of pulling force. This is what keeps the overhead line tight.
Nice to see a preformed cylindrical mass here. Many such weights in Europe are simply stacks of bricks lashed together!
