  • Fluid chain-tightener
    Patent number: 7033295
    Abstract: Chain tightener comprising a first supporting surface (11) on one branch (12) of the chain and a second supporting surface (13) on the other branch (14) of the chain with each supporting surface (11,13) being connected to a respective drive piston (19,119,20,120) into which is fed fluid for thrust in a tightening direction of the respective chain branch with the hydraulic circuits of the two pistons interconnected so that when one piston (19,119 or 20,120) is thrust in the direction opposite tightening from the tight branch of the chain it sends its fluid into the other piston (20,120 or 19,119) to thrust it to tighten the corresponding slack chain branch.
