With the variation of temperature cables tend to contract/expand and this systems allows the cables to do so freely with a constant tension provided by the weights.

minus-square@someacnt_linkEnglish1•3 hours agoIs it simple? It looks quite complicated, but maybe that’s just me forgetting how to compute forces.

What’s it pull?
