What does 6×19 IWRC mean?
6×19 IWRC. The 6×19 classification of wire ropes includes standard 6 strand, round strand ropes with 16 through 26 wires per strand. This is a good rope to withstand abrasion or crushing on the drum.
Which is stronger, wire rope or chain?
wire rope is stronger the cross sectional area of a wire is usually greater than that of the links in a chain. Therefore, more pressure is exerted on a chain than on a wire if each are holding the same weight. It depends on the material, but in most practical cases the wire rope will be stronger.
How is wire rope specified?
• Multi-wire strands laid geometrically around a core • Wire rope is specified by the number of strands in the rope, the number of wires in each strand, and a description of the type of construction. For example, the notation 6×7 FC means that the rope has six strands, and there are 7 wires in each strand around a fiber core.
What is IWRC wire rope?
Wire core rope is abbreviated “IWRC”, for Independent Wire Rope Core, and is approximately 10% stronger than fiber core wire. Torque is a problem inherent in twisted ropes. As the rope comes under strain, it tries to “unlay” and creates twisting forces, which may cause the wings of trawls or bridles to spin up.
