How to Increase the Life of a Crane Wire Rope?

Cranes are used in almost all lifting and rigging operations. They are almost always in demand in the mining, construction, and oil and gas industries. It is one of the fastest-growing markets. Worth $33.61 million in 2021, the global cranes market is projected to reach $56.29 million by 2030, at a CAGR of 4.8%.

And crane wire rope is a critical part of the whole crane assembly. The wire rope needs to meet manufacturing specifications. And as these industrial wire ropes are often expensive, you must take good care of them. The longer you can use them, the better.

Fortunately, it is possible to increase their lifespan with proper wire rope maintenance.

Let's learn more about crane wire ropes, their maintenance, replacement, and usage.

Factors Affecting the Life of Wire Rope for a Crane

As a crane wire rope supplier, vendors and riggers often ask us about the factors affecting the life of crane ropes. Most crane wire ropes are designed to last long, endure stress, and even brave harsh weather conditions. However, they do undergo a lot of wear and tear, resulting in gradual damage. The factors affecting the lifespan of these industrial wire ropes include: 

1. Tensile Strength

The tensile strength of a wire rope is crucial in determining its lifespan for crane usage. High-quality wire ropes with superior tensile strength can withstand the stresses of lifting heavy loads for extended periods, ensuring your crane operates safely and efficiently.

2. Abrasion Resistance

When using wire rope for a crane, it often gets exposed to harsh environments that can lead to abrasion. Use crane wire ropes with more abrasion resistance if you are working in harsh environmental conditions. Only these ropes will last longer and require less maintenance.

3. Fatigue Resistance

Fatigue is also a common cause of failure when using wire rope for a crane. But wire ropes with excellent fatigue resistance are available. They can withstand repeated bending and flexing.

4. Corrosion Resistance

The last factor affecting the lifespan of industrial wire ropes is corrosion. You can opt for zinc-coated or steel wire rope for a crane. These industrial ropes have higher corrosion resistance, ensuring your crane operates efficiently in the harshest environments.

Ensuring Proper Wire Rope Maintenance

As you can see, maintenance is the key to ensuring your wire ropes remain in excellent working condition. It also prevents potential accidents and damage to the load. 

Wire rope maintenance often involves:

1. Inspection

Inspection is the first step in wire rope maintenance. It ensures the safety and reliability of cranes. Visual inspection involves examining the industrial wire ropes for signs of wear, corrosion, and damage. Running a cloth along the cable can also help you identify potential damage.

Non-destructive testing involves using specialized equipment to identify defects not visible to the naked eye, such as internal wire breaks. Regular inspection is essential to identify potential problems early and take corrective action before they lead to failure.

2. Lubrication

Lubrication reduces friction between wire strands, preventing them from rubbing against each other and causing wear. Proper lubrication also helps protect the industrial wire rope against corrosion. Different types of lubricants are available, including oils, greases, and dry films. Choose the right one depending on your application and environment.

Understanding the Best Practices for Increasing the Life of Wire Rope

Apart from regular wire rope maintenance, you will also need to take a few precautions to ensure the safety and efficiency of the crane ropes. 

Here're a few best practices you can't miss. 

• Use a suitable cable rope for the job. When selecting wire rope for a crane, ensure it meets the required strength and abrasion resistance for the loads and conditions of the job.
  
  
• Always follow recommended installation and operation practices. They are essential in minimizing stress. So, check the manufacturer's guidelines and industry standards for installation and operation.
  
  
• Regularly inspect and maintain the wire ropes. It can detect wear, corrosion, and damage early, allowing for timely repairs.
  
  
• Make sure every inspection includes measuring the diameter for acceptable tolerance and checking the sheave for proper tolerance. Similarly, the life of the wire also depends on the correct tension on the drum. So, always choose the diameter specified by the equipment manufacturer. If the diameter is smaller than specified, the stress on the rope will increase, causing failure. But, using a larger diameter rope can result in shorter service life because it gets pinched in the sheave and drum grooves.
  
  
• Poor spooling will also damage your wire rope leading to a shorter life span. When installing the wire rope, be sure every wrap on the first or foundation layer is tight and without gaps. And ensure the following layers lay in the grooves formed between adjacent turns of the preceding layer of rope.
  
  
• Train your operators and riggers to use the wire ropes correctly. Rigging training ensures operators are familiar with the safe use and maintenance of the cable ropes.
  
  
• Store and handle the wire ropes properly. Store them in a dry, clean environment and away from chemicals and contaminants. This helps prevent corrosion and damage.
  
  
• Replace the wire ropes when needed. They have a limited lifespan, and replacing them when necessary is critical. Follow crane wire rope supplier or manufacturer recommendations for replacement intervals based on usage and condition.
