The structure and composition of wire rope

Wire rope is a highly engineered product consisting of several key components. Its structure and composition determine its strength, flexibility, resistance to wear, and suitability for different applications. Here’s a breakdown of its structure and composition:

1. Core

The core is the central part of the wire rope, around which the strands are wound. It provides support and helps maintain the rope’s shape. There are three main types of cores:

  • Fiber Core (FC): Made from natural or synthetic fibers, providing flexibility and cushioning for the strands.
  • Independent Wire Rope Core (IWRC): A small, separate wire rope acts as the core, providing additional strength and resistance to crushing.
  • Wire Strand Core (WSC): A single wire strand acts as the core, offering greater strength than fiber cores but less than an IWRC.
2. Strands

Strands are groups of individual wires twisted together around the core. The number of wires and their arrangement within the strand affect the flexibility and strength of the rope. The strands are typically laid helically around the core.

  • Standard strand construction: The most common types include 6-strand, 7-strand, and 8-strand wire ropes, each with a different wire arrangement.
3. Wires

The individual wires within the strands are made of materials such as high-carbon steel, stainless steel, or galvanized steel, depending on the application. The wires are responsible for bearing the load.

  • High-carbon steel: Offers high strength and is the most common material.
  • Stainless steel: Provides corrosion resistance for environments exposed to moisture or chemicals.
  • Galvanized steel: Steel coated with zinc for added corrosion resistance.
4. Lubrication

Wire ropes are often lubricated during the manufacturing process to reduce friction between the wires and strands, minimize corrosion, and extend the rope’s service life. The lubrication can be applied externally or internally to the core.

5. Construction Configurations

Wire ropes come in different constructions depending on the number of strands and wires per strand:

  • 6×19 construction: Six strands, each consisting of 19 wires. This type offers a balance between strength and flexibility.
  • 6×36 construction: Six strands, each with 36 wires, providing greater flexibility but lower abrasion resistance than 6×19.
  • 35×7 non-rotating construction: Used in lifting operations, where rotational stability is required, such as in cranes.
6. Coatings

In addition to galvanizing, wire ropes can have coatings like plastic (EPIWRC) for additional protection in specific applications, such as marine or rotary drilling.The selection of wire rope for specific uses involves balancing factors such as strength, flexibility, resistance to abrasion, corrosion, and fatigue, depending on the operating environment and mechanical requirements.

How Do You Correctly Install Duty Cycle Crawler Cranes Wire Rope?

Correctly installing wire rope on duty cycle crawler cranes is critical for ensuring safety, extending the rope’s lifespan, and maximizing crane performance. Here’s a step-by-step guide to installing wire rope properly:

1. Prepare for Installation

Before installation, gather all necessary tools, equipment, and personnel to ensure the process goes smoothly and safely.

  • Inspect the new wire rope: Examine the wire rope before installation for any signs of damage, such as kinks, broken strands, or corrosion. Even new wire ropes can sometimes suffer from transport or storage issues.

  • Review the crane’s manual: Familiarize yourself with the crane manufacturer’s guidelines for installing wire rope, including proper routing, tensioning, and drum winding procedures.

  • Check the drum and sheaves: Inspect the crane’s drum, sheaves, and other components for wear or damage that could affect rope performance. Ensure the sheave and drum grooves are free from debris and are in good condition.

2. Handle the Wire Rope Correctly

Wire rope is prone to kinking and twisting if not handled properly during installation. Follow these guidelines:

  • Use a turntable or reel stand: Place the wire rope on a reel or turntable that allows it to unwind smoothly. The rope should come off the reel or drum in the same direction it will be wound onto the crane’s drum.

  • Avoid dragging the rope: Never drag wire rope across the ground or sharp surfaces, as this can cause damage or contamination.

  • Unwind, don’t twist: Ensure the wire rope unwinds smoothly and does not twist or form loops. Twisting can lead to internal damage and significantly weaken the rope.

3. Attach the Wire Rope to the Drum

Follow these steps to secure the wire rope to the drum correctly:

  • Anchor the rope: Securely attach the end of the wire rope to the drum’s anchor point or clamping system. Ensure the rope is clamped or anchored as per the crane manufacturer’s specifications, ensuring it will not slip or come loose under load.

  • Ensure proper rope direction: The rope should be wound in the correct direction on the drum, either left-hand or right-hand, as specified by the crane’s operating manual. Incorrect winding can cause operational issues.

  • Wind under tension: When winding the rope onto the drum, ensure there is sufficient tension in the rope to prevent it from loosening or “birdcaging” on the drum. Applying tension can be done by pulling the wire rope taut with a truck or another piece of equipment.

  • Ensure smooth winding: Make sure the wire rope is wound smoothly, with each layer neatly arranged. Avoid crossing or overlapping layers, as this can lead to crushing or uneven wear.

4. Install the Rope Over the Sheaves

Properly routing the wire rope over the crane’s sheaves ensures optimal performance and minimizes wear.

  • Use the correct sheave size: Verify that the sheaves and pulleys are of the correct size and diameter for the wire rope being used. Using undersized sheaves can cause sharp bends, reducing the rope’s strength and lifespan.

  • Check for alignment: Ensure the wire rope is aligned properly with the sheave grooves. Misalignment can cause uneven wear, abrasion, or even derailment of the rope.

  • Monitor for twist: Watch for any signs of twisting or untwisting as the rope passes through the sheaves. Excessive twisting can lead to rotation of the load or premature rope failure.

5. Tension and Adjust the Wire Rope

After installing the wire rope, it’s crucial to ensure that it’s properly tensioned for optimal performance.

  • Pre-tension the wire rope: Once the rope is installed, apply light tension across the rope’s entire length by lifting a load slightly off the ground. This helps seat the rope in the drum grooves and over the sheaves, reducing the risk of slack or loose layers.

  • Cycle the crane: Operate the crane under light loads, cycling through its full range of motion several times. This allows the rope to stretch and settle into place. Make any necessary adjustments to the rope’s tension during this process.

6. Secure the End of the Rope

Once the wire rope is properly installed and tensioned:

  • Secure the rope’s free end: If there is excess wire rope, properly secure the free end to prevent it from unraveling or getting caught during operations. Use clamps or wire rope grips as required.

7. Perform a Final Inspection

After installation, conduct a thorough inspection of the wire rope and crane setup:

  • Check tension: Ensure the wire rope is properly tensioned with no visible slack or looseness on the drum or through the sheaves.

  • Inspect for twists or kinks: Look for any twists, kinks, or uneven winding on the drum. Correct any issues before putting the crane into full operation.

  • Lubricate the rope: If needed, apply a compatible lubricant to the wire rope to reduce friction between the strands and prevent corrosion.

8. Document and Track the Installation

Keep a detailed record of the wire rope installation, including the date, rope specifications, and any observations made during the installation process. Regular maintenance and inspections should also be documented to track the rope’s condition over time.

9. Monitor During Initial Operations

During the first few cycles of crane operation with the new wire rope, observe the performance closely to ensure the rope is functioning properly. Adjustments to tension or positioning may be required as the rope settles.

Key Points to Remember:

  • Always follow the manufacturer’s specifications for rope installation, tensioning, and winding.

  • Handle the rope carefully to avoid kinks, twists, or damage.

  • Ensure proper alignment and smooth routing through sheaves and over the drum.

  • Regular inspections and maintenance after installation are critical for long-term performance.

By following these steps, you can ensure that the wire rope on duty cycle crawler cranes is installed correctly, performs optimally, and has an extended service life.
