How is a steel wire rope capable of carrying tens of tons made? Why is it not easy to break?

Why are steel wire ropes that can withstand tens of tons of weight, such as lifting ropes for cranes and arresting ropes for aircraft carriers, not easily broken? How are they made?

Steel wire rope is composed of steel wire, rope core, and lubricating grease. It has the advantages of high strength, light weight, and stable operation. It plays an important role in lifting, pulling, tensioning, and bearing. Especially in the fields of metallurgy, mining, oil and gas drilling, machinery, chemical engineering, aerospace, etc., it has become an indispensable component or material.

Taking the example of the arresting cable on an aircraft carrier, if a carrier based aircraft with a speed of 20 tons or more and a speed of 200 kilometers per hour comes to a complete stop within 3 seconds, the maximum pulling force that the arresting cable can withstand is about 87 tons. Each of these types of arresting ropes consists of 6 strands of steel wire rope, with each wire rope consisting of 12 main wires, 12 middle wires, and 6 triangular thin wires.

Wire rope are generally composed of information such as the number of strands, the number of steel wires, the diameter, and the rope core. The number of strands refers to how many steel wires a steel cable is composed of, the number of steel wires refers to how many steel wires are in each strand of the steel cable, the diameter refers to the diameter of the steel cable, and the core refers to the central part of the steel cable. Steel cables are made of high-strength steel wires that can withstand significant tension and bending forces. Under the support of high carbon steel, both elasticity and fatigue limits are high. This high-strength characteristic allows steel cables to withstand a large amount of weight and pressure, while also maintaining a long service life.

As the most technically demanding and demanding rigging in the world, the price of such a rope reaches 1.5 million yuan.

How is a regular steel wire rope twisted from steel wire into a rope, other than this special purpose steel wire rope?

It mainly goes through three basic processes: drawing, twisting, and tying. The raw material for producing steel wire is high-quality hot-rolled high carbon steel wire rod. Before production, it is necessary to conduct a warehouse inspection on the raw materials. Qualified steel wire can be used for the first drawing process. Only through surface acid washing, phosphating, drawing and other treatments can we obtain rope making steel wire that meets the requirements in terms of size, shape, performance and surface quality.

In order to improve performance, all steel wire ropes must be coated with oil. Some also require coating the surface with metal, alloy, or plastic. After completing this operation, you can start the second step of twisting. The qualified steel wire drum rolls on the I-wheel of the twisting machine, and the steel wires are arranged neatly. After passing through the distribution reel, pressure shoe, and rear transformer, the tight wire is finally twisted. Place the rope strands on the rope winding machine and arrange them in a spiral shape around the centerline of the rope core, thus producing a long steel wire rope.

Although steel wire rope is sturdy and not easy to break, it does not mean that it can be used continuously. Regular maintenance can extend the service life of steel wire rope. The most important thing is to add lubricating oil to the steel wire in a timely manner. Common simple oiling methods include dripping, spraying, and brushing.

Wire ropes are the most important items when ship anchoring . Stainless steel wire ropes are a cable consisting by several strands of twisted metal wire, normally in steel material, different diameter are available.
