Wire Rope and Mechanical Cable Information Wire rope and mechanical cable is wound from high-strength metal strands for structural, mechanical actuation and motion control applications. Suppliers typically list the number of wires per strand followed by the number of strands per rope or cable. For example, products with a 7 x 19 designation have seven strands per cable and 19 wires per strand. Some wire rope and mechanical cable products are enclosed in a metal wrap or jacket to provide...

Q:
What new technologies are influencing wire rope and mechanical cable design?
11 answers
Answers:
High SWL of new cranes, reliability of cranes and machines in process (availability) Requirements of longevity of wire-ropes, constant quality Higher density of pre-material, e.g. Dyneema or steel-materials
~Stephan S, Marketing/Sales, Hamburg, Germany
Currently, in the lift industry gearless machines are being used which require a much higher angle of wrap in some applications. Therefore, the life of the ropes is being reduced due to reverse bending.
