Claim 19:
20. A method for inspecting a quality and/or condition of an elongated composite member, which is a load bearing member of a hoisting rope of a hoisting apparatus or a precursor of the load bearing member, the method comprising:
providing the elongated composite member;
changing a temperature of said elongated composite member by cooling said elongated composite member via a flank thereof, the cooling including inducing heat transfer from the elongated composite member to a fluid that is in relative motion with respect to the elongated composite member such that the elongated composite member is in a cooled state after said changing of the temperature is complete;
scanning said elongated composite member from a lateral side thereof with a thermal imaging device after said changing of the temperature is complete and the elongated composite member is in the cooled state; and
creating thermographic images of said elongated composite member based on the scanning,
wherein in said providing said elongated composite member, said elongated composite member is provided having heat accumulated from a manufacturing process of the elongated composite member or from a manufacturing process of the hoisting rope including the elongated composite member.
