Materials

The materials of the following components are to be used for manufacturing the universal fairleads.
— Frame and other plates：weldable steel plates having a yield point of not less than 235N/mm2 except frame with rope guide for nominal size 400A，400B and 400C shall be made of weldable steel plates having a yield point of not less than 315N/mm2.
— Roller：weldable steel plates having a yield point of not less than 235 N/mm2 except rollers for nominal size 400A，400B，and 400C shall be made of weldable steel plates having a yield point of not less than 315N/mm2，or equivalent steel tubes.
— Axle：carbon steel having a yield point of not less than 345N/mm2.
— Bush：brass or bronze or equivalent.

Manufacturing and inspection

All surfaces of the universal fairleads，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 universal fairleads shall be coated externally with an anti-corrosion protective finish.
All rotating parts shall be provided with greasing.

a Welding with chamfering is available based on the same welding volume/strength b Welding otherwise mentioned in the figures in this international Standard and in this table: minimum leg length is to be 1/2 of thinner plate thickness. c The SWL is the maximum application rope tension. The SWLs shown in this table are for reference only. These are based on the loadings as mentioned in Annex A . The “SWL” may be adjusted depending on the actual loading conditions, and the actual marking shall be agreed between the user and the manufacture. d The calculated weight is for reference only excluding foundation.
