Panama chocks A type

ISO 13728:2012(E)

Materials

The following material shall be used for manufacturing the Panama chocks: Chocks:steel casting material having a yield point of not less than 235 N/mm2 or equipment . The carbon contents of the steel casting not be more than 0.23% considering welding.

Construction

The foundation of the Panama 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 of the Panama chocks to hull construction without any plastic deformation or cracks.

Manufacturing and inspection

All surfaces of the Panama chocks, including welding,shall be free from any visible flaws or imperfections All surfaces in contact with the ropes shall be free from surface roughness or irregularities likely to cause damage to the ropes by abrasion The Panama chocks shall be coated externally with an anti-corrosion protective finish.
