Double Cardan enables stainless steel spring operating with always perfect axiality and parallelism, regardless of traction angle the vessel exercises with its movements. This is an ESSENTIAL factor versus twisting spring fatigue – as can be seen from stopper chains twisting – that could lead to an early breakup of actual spring. Double Cardan is equipped with appropriate shackles for a perfect fitting.
This is a girdle made in double polyester fabric with longitudinal VELCRO closure and holding belts to mooring ropes to neatly contain power supply cables and water hoses on the ground. It is also equipped with a special stainless steel belt specially shaped in order to be twisted and to give elegant stifness in use. It is made in tempotest, and UV rays resistant and it has a 4 years guarantee.
Shackle Top-Line is a patent by Douglas Marine and it is used as ascent aid on bridges. It has a single connection plate for an assembly without wheelbase drilling problems. The carry-shackle sockets are watertight to avoid potential bridge infiltration. Shackle placement and disassembly are very quick and safe.
