Shock absorber (recreational shipping)

Shock absorber with coils
Classic shock absorber
Mooring springs

Cush , Mooring springs and Zugdämpfer be at mooring lines of boats used and other small boats to strong jerks caused by the wake and waves attenuate.

Mooring lines of yachts, as opposed to commercial shipping , not tightened and usually hang by lightly so that the relatively light boat always something can move. The shock absorber acts as an elastic point, which expands in the event of a sudden load and slowly transfers the tensile energy to the mooring line and cleat on board. This minimizes damage caused by extreme loads.

Executions

  • Shock absorbers made from ethylene-propylene-diene rubber (EPDM) are easy to assemble, withstand stormy weather and are insensitive to UV radiation and seawater . The expansion of the shock absorber can be adapted to the conditions of the berth by the number of turns.
  • Classic shock absorbers, also known as jerk fenders, are also made of EPDM and are accordingly resistant. However, the degree of damping cannot be varied.
  • Contact springs are springs made of steel or stainless steel with limited elongation . If you use it between a chain attached to land and the mooring line, the line is also protected from shame filing . Older metal springs, however, tend to make annoying noises.
  • Pull dampers ("Bungy" or "Smart Snubber") are mounted individually or several times on the mooring line without the need for a free end. The degree of damping can be varied afterwards.
  • Ready-made mooring lines with integrated shock absorbers.
