Tensioner:

Tensioner:-

A tensioner is a device that applies a force to an object to maintain it in tension. Often the amount of force is adjustable. There are tensioners for applying a tensioning force to drive belts and chains, fibers, and bolts. One type of tensioner is a large industrial spring. A tensioner is used between two objects that should be kept together but that make relative, more or less unpredicted, motions towards each other. The tensioner makes sure that independent of the motion the connection remains intact, without elements becoming overstressed. An anchor chain could be defined as the easiest tensioner.
