a. is the relative angle of ropes on the roller fairlead. b, SWL is the maximum applicable rope tension based on ( = ) and 16 ( = 2 ) deflection of rope direction by roller fairlead. SWLs shown in the Table are for reference only. These are based on the loadings as mentioned in Annex A. SWL may be adjusted depending on the actual loading conditions, and the actual marking is to be per the agreement between the user and the manufacturer. c. P and W is for reference. The opening size on the shell or bulwark is to be determined considering overhauling space of the roller. |
