The overall damping, at 60-70%, is given by the compression of the spring made of a special stainless steel alloy with high elasticity. Under conditions of higher stress, the Mollaflex-Elastomer component intervenes. In case of failure of the steel spring, by the end of its technical cycle, the action of the Mollaflex-Elastomer component intervenes, which continues to perform its cushioning function, preventing possible accidents and damage that the boat may suffer if not properly moored, in rough conditions. It is very important to note, therefore, that this Mollaflex-Elastomer component not only greatly increases the damping load, along with the mechanical work of the already very elastic spring, but can replace the spring in the case illustrated above.
