JIS F 2005-1975 Closed Chock

JIS F 2005-1975 Closed Chock    

The closed chock is made according to the JIS F 2005-1975 standard of the Japanese Standard Association. The JIS F 2005 closed chock is one of the commonest mooring closed chocks used on vessels. The marine chocks are used for temporary mooring to guide rope from inboard to outboard a large vessel and applied at the vessel’s bow bulwarks to prevent wear and tear of the mooring line. The nominal size of 100mm to 200mm closed chocks are made of common cast steel and there are four stiffeners around the chock. The nominal size of 250mm to 500mm closed chocks are made of cast steel according to the requirement of standard JIS G 5101, and there are five stiffeners around the chock. The surface should be polished, galvanized and painted smoothly without any visual flaws, edges and burrs, which can reduce the friction of the mooring and towing ropes. The chocks can be supplied with foundation, which can be designed and manufactured according to the requirement on the vessel. The chocks are welded at a bow ship. YSmarines provides a high quality closed chock with the certificate of CCS, BV, ABS, etc.
