Introduction:
The closed chock is made according to the standard of ISO 13729. The type of the mooring chock is normally applied for the ship which uses wire ropes. The radius of the surface was designed based on the bending ratio of rope through the chock of not less than twelve times the wire rope diameter. The foundation of the closed chocks shall be determined by considering the actual load direction. The foundation and welding connections to the hull shall be guaranteed reliable transmission of the maximum loading to hull construction without any plastic deformation or cracks. The ISO13729 chocks can also be classified into two types by its installation site including deck-mounted closed chock and bulwark mounted one.
The marine chock is an important mooring equipment. There’re different types of mooring chocks with different standards including ISO, JIS, DIN, NS. SWL will be from 8KN to 3000KN according to your requirements. In the process of mooring ship, it bears huge loads. Usually, the ship bollards and mooring chock are for the whole ship mooring use. The general bow and stern of ship block the bollard fairlead, quantity large. Of intermediate section above without or bollards, fairlead rarely. Fairlead is oblique chock more insurance, because it is closed, the cable will not jump out. The triangle chocks are widely used for small boats and different vessels, such as container vessels, tankers, bulk carriers, tug, dry cargo vessels, etc.
Marine mooring chock has two types: deck mounted chock & bulwark mounted chock. The material is casting steel ZG230-450 normally. IACS approved quality to withstand all conditions. Certificated by BV, ABS, LRS, DNVGL, RS, IRS, CCS, KR, NK, etc. We could also provide you with a customized design with CAD drawings.
