With the continuous development of the shipbuilding industry, the chain stopper more extensive range of applications, the importance is growing. Its compact structure, stable performance and high reliability. For chain stopper I have described below instructions.
The chain's system types:
Spiral chain stopper: the two plywood and there are threaded screw down with the handle of a composition. When you turn the crank so that the two clamping jaws that grip the chain; contrary loosen plywood, chain can freely. Although its elastic action is slow, but the structure is simple and reliable, so medium and small vessels still widely used.
Knife-type chain stopper: simple structure, rapid operation. But its large size when cumbersome, generally used only on small and medium sized vessels.
Chain stopper: consists of a chain hook, a screw and a short telescopic chains. It is fixed with a shackle on deck when using the chain hook on a horizontal chain link, and then tighten the screws stretching that cho taut chain. It is often associated with spiral chain system supporting the use of a spiral chain stopper auxiliary devices.
