The History of Wire Rope

Wire rope, as we recognize it today, boasts a rich history spanning nearly two centuries. The innovation dates back to between 1831 and 1834, when German mining engineer Wilhelm Albert sought to enhance safety and efficiency in the Harz Mountains’ mining operations. Albert’s original design featured four three-stranded wires, which provided unprecedented strength compared to the previously used natural fiber ropes and metal chains.

The history of modern wire rope further evolved when L.D.B. Gordon, inspired by Albert’s invention, encouraged Robert Stirling Newall in Dundee, Scotland, to invent a wire rope manufacturing machine. Newall’s machine successfully produced four-strand wire ropes, each strand containing four wires, enabling large-scale production and innovation. Gordon, Newall, and Charles Liddell established R.S. Newall and Company, and in 1840, Newall secured a patent for “certain improvements in wire rope and the machinery for making such rope.”

American innovation followed closely. In 1841, John A. Roebling began producing wire rope for suspension bridges, enhancing the safety and feasibility of long-span structures. Around the same time, Josiah White and Erskine Hazard of the Lehigh Coal & Navigation Company (LC&N Co.) introduced wire rope to coal mining and railroad transportation projects. The use of wire rope in the Ashley Planes Project in Pennsylvania in 1848 dramatically reduced return times for coal cars, increasing both efficiency and capacity.

Wire rope’s impact was felt globally, particularly in 1874 when Adolf Bleichert & Co. pioneered bi-cable aerial tramways for mining in Germany’s Ruhr Valley. These technological advancements later found applications in military transportation for the German Imperial Army and the Wehrmacht, eventually spreading across Europe and the United States.

Since the 1800s, wire rope technology has continually advanced. Modern improvements include the use of high-tensile steel, advanced coatings for corrosion resistance (like galvanization), and specialized wire rope constructions for enhanced flexibility and strength. Today, wire rope remains an essential component in infrastructure, transportation, energy, and industrial processes worldwide, forming the backbone of our modern built environment.

Design

Production Process

Wire rope is manufactured by tightly twisting or braiding individual metal wires into strands, which are then helically wrapped around a central core. The number of wire filaments in each strand can range from two to dozens, depending on the application’s requirements for tensile strength, flexibility, and load-bearing capacity.

A key aspect of wire rope construction is the core. The core can be a fiber rope, a wire strand core (WSC), or an independent wire rope core (IWRC). For applications demanding maximum strength and fatigue resistance—such as crane cables, elevator cables, or heavy-lift slings—the IWRC is often preferred. An IWRC typically increases a wire rope’s overall strength by at least 7.5%, enhances flexibility, and helps prevent crushing or distortion under load.

Materials

Wire ropes can be engineered from a variety of metals to match their intended use. While specialty ropes may incorporate aluminum, nickel, copper, titanium, or bronze, the most common material by far is steel—valued for its exceptional strength, ductility, and fatigue resistance. Steel wire rope types include galvanized wire rope, bright (ungalvanized) wire rope, stainless steel wire rope, and cold-drawn carbon steel wire rope.

Galvanized steel wire rope is favored for outdoor, marine, and corrosive environments, as the zinc coating provides long-lasting protection against rust and abrasion. Stainless steel wire rope is chosen for applications where superior corrosion resistance is required, such as in food processing, chemical plants, and marine rigging. Bright wire rope, which is ungalvanized, is used in non-corrosive indoor settings, while cold-drawn carbon steel wire rope offers high tensile strength for demanding lifting and pulling tasks.

In aerospace and aviation industries, galvanized aircraft cable is used for control cables, safety cables, and emergency systems due to its optimal balance of strength, flexibility, and corrosion resistance.

Design Considerations and Customization

When selecting or specifying a custom wire rope, it’s essential to consider a range of design factors:

• Operating Environment: Will the wire rope be exposed to moisture, saltwater, chemicals, or extreme temperatures?
• Corrosion and Rust Resistance: Is a galvanized or stainless steel finish necessary?
• Flexibility vs. Strength: Does the application require extra pliability for pulleys or maximum tensile strength for lifting?
• Diameter and Breaking Strength: What are the minimum strength requirements, and what is the intended safety factor?
• Rotation-Resistance: Is the cable required to resist spinning or twisting under load?
• End Fittings and Terminations: Are there specific hardware or attachment requirements?

Manufacturers can further customize wire rope by color-coding for easy identification, adding corrosion-resistant coatings, or incorporating plastic sheathing to prevent fraying and wear when cables are routed over pulleys or exposed to repeated abrasion.

Are you trying to determine which wire rope design is best for your application? Consult with a wire rope supplier or manufacturer to discuss your specific needs, load requirements, and safety standards.

Types

Wire rope is classified according to the number of strands and number of wires per strand—a system that allows end-users to quickly gauge the cable’s strength, flexibility, and suitability for different tasks. Wire rope distributors and suppliers also provide technical specifications regarding core type, construction, length, weight limit, and accessory compatibility.

Here are the most common wire rope configurations:

• 6 x 19, 6 x 25, 6 x 26, 6 x 36: These constructions feature six strands, each with 19, 25, 26, or 36 wires, respectively. The 6 x 19 is popular for its balance of flexibility and abrasion resistance, making it ideal for winches, cranes, and general-purpose lifting.
• 7 x 7, 7 x 19, 19 x 7: These cables are often used in aircraft, control cables, and marine applications. 7 x 19 construction, in particular, is known for its flexibility and is frequently used for garage doors, sailboat rigging, and exercise equipment.
