Introduction:
The Panama chocks are made according to the ISO 13728 standard and are normally adopted for ships passing through the Panama Canal, which are normally assisted by locomotives using steel towing wire. They meet normal mooring requirements and Panama Canal requirements. The material is steel casting material, having a yield point of not less than 235N/mm2 or equivalent. The carbon contents of the steel casting for ISO13728 chock shall not be more than 0.23% considering weldability. The nominal size of the chock is denoted by reference to the width of the opening, in millimeters, which are 310mm and 360mm. It can be classified as deck-mounted Panama chock and bulwark mounted one according to their installation site.
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.
