Say that you want to tension the chain on an arm robot. The chain is going vertically, so you add springs to each side of holes and the tensioner now just hangs: suspended by springs and it still tensions the chain. Also you can attach zip ties or springs to limit how far it floats or if you just want it to stay stationary. Example shown below:


Look at the white tensioner on the lift mechanism, it is suspended by springs and zip ties. The sprockets lifting the arm were of different sizes (a 60 tooth and a 15 tooth), so the tensioner had a tendency of diving down to the smaller sprocket.
