You can buy a cheaper anchor winch by reducing the chain diameter without decreasing the chain stretched length and strength by choosing
AQUA 7 is the chain for anchor winches and designed to ensure a tensile strength of 70kg per mm2.
|Artcle Code||Calibrate hot dip galva chain Description||Weight kg/m||Grade||Working load limit kg||Breaking load limit kN|
The benefit of AQUA 7 is not only its better mechanical strength and therefore its effectiveness in solving specific safety problems associated with busy waters and sea beds but is, above all, the answer to endless design problems associated with the weights, volumes and design of anchor winches, as well as the most common problems experienced by the pleasure boatman, such as the optimal stretched length of the chain.
The graph highlights the breaking load of Aqua7 (the example shown is for a dia. 8 mm chain with breaking load of around 7000 kg) compared to traditional breaking loads (grade 30 of the chain according to DIN 766 mm.8 standard) and to the grade 40 of the Aqua 4 chain mm.8 The greater elastic field (the straight section of the curve) of Aqua 7 ensures a higher working capacity (working load) in respect to traditional chains.
