Wire Rope

A wire rope can meet the stated load and still be the wrong choice for the job. That is where many selection problems begin. The issue is not always that the rope was undersized; it is that critical parts of the application were never weighed properly in the first place. Bending conditions, duty cycle, environment, and whether the rope is used for lifting or...

A bird-caged wire rope creates a decision problem before it creates a replacement order. The rope has already changed shape, the outer strands have already moved away from the rope body, and the damaged section no longer deserves normal service assumptions. Customers who know wire rope often call this bird caging by name. Other customers know something looks wrong before they know the technical...

Recognizing when wire rope has reached the end of its service life is a critical safety measure for lifting, rigging, or hoisting operations. No one wants to risk a sudden cable failure that could endanger personnel or damage valuable equipment. Understanding specific “discard” criteria ensures that worn or compromised rope is removed from service before an accident happens. Below are the most common signs...

For any operation that uses synthetic ropes, adequate chafing protection is extremely important.  There are a large variety of synthetic fibers that serve as chafe gear and chafe protection. Chafe gear helps to prevent substantial wear and tear on synthetic rope, which increases the longevity of the strands. Without chafe gear, wire ropes would have a much shorter lifespan and would degrade much faster...

At Bilco Group, selecting between our steel wire rope and high-performance synthetic rope is no longer a matter of tradition. Our modern synthetic ropes made from ultra-high molecular weight polyethylene (UHMWPE) fibers can match the tensile strength of steel rope while weighing only one-ninth as much. This dramatic weight savings changes how cranes, winches, and rigging crews operate: lighter lines reduce equipment wear, speed...

Wire ropes are integral components for many buildings, machines, and structures. This material is comprised of contiguous wire strands that are wrapped around a centralized core.  It is important to lubricate wire ropes in order to limit friction and prevent corrosion. There are two main types of wire rope lubricants: penetrating and coating.  A penetrating lubricant contains a solvent that transports the lubricant into...

Wire Rope Rigging supplies tend to fail when paired with the wrong rope. The label on the old cable does not tell the whole story. A customer may ask for 7x7, 7x19, or GAC wire because that label appeared on a prior order, an old invoice, or the cable being replaced. We still need to know what the cable is doing in the application....

Fatigue life in large-diameter wire ropes is a key concern for professionals relying on heavy-duty lifting and surface mining. Despite advancements in wire rope manufacturing, one recurring issue is premature rope failure when operating under excessive loads. Research shows that catastrophic failures frequently occur when large-diameter wire ropes are subjected to loads above 45% of their ultimate tensile strength (UTS). This finding underscores the importance of...

A Crucial Safety Perspective In industrial operations, wire ropes are critical in various applications, from construction to maritime activities. However, with their extensive use come significant risks, particularly abrasion, bird caging, and kinking. These issues are not just technical concerns; they threaten business operations and human safety. The Dangers Posed by Wire Rope Damages Abrasion in wire ropes typically occurs when the ropes rub...

One of the most common questions we get asked is the difference between 7x19 and 7x7 wire cables. This question is frequently asked because these two types of cables are the most common cable constructions for many industries, including aircraft controls. Because of the number of mechanical applications that both cables boast, it is essential to recognize the difference between the two for your...
