Exploring the Anatomy of 4x36WS (1-7-7+7-14) + FC Steel Wire Rope

4x36WS (1-7-7+7-14) + FC Steel Wire Rope: In the industrial world, the efficiency and safety of lifting, hoisting, and material handling operations depend heavily on the strength and reliability of the wire ropes used. Among the wide range of wire ropes available in the market, the 4x36WS (1-7-7+7-14) + FC steel wire rope stands out for its superior flexibility, fatigue resistance, and performance under dynamic loading conditions.

At SSTC (Safe and Secure Trading Company) in Saudi Arabia, we are proud to offer premium-grade steel wire ropes that meet international standards and serve critical roles across sectors like oil & gas, construction, marine, transportation, mining, and logistics. This blog explores the full anatomy, structure, and industrial utility of the 4x36WS + FC wire rope, focusing on its advantages and real-world applications in Saudi Arabia’s ever-growing infrastructure and industrial landscape.

Understanding the Construction: What Does 4x36WS (1-7-7+7-14) + FC Mean?

The naming of wire ropes can seem technical, but each element of the designation 4x36WS (1-7-7+7-14) + FC has specific meaning and engineering significance.

Let’s break it down:

• 4x36WS: This denotes a wire rope composed of 4 strands, each containing 36 individual wires. The “WS” stands for Warrington-Seale, a strand design that combines both large and small wires for optimal performance.
• (1-7-7+7-14): This part details the anatomy of each strand:
  • 1 wire at the center
  • First layer: 7 wires around the center
  • Second layer: another 7 wires
  • Third layer: 7 more wires
  • Fourth layer: 14 outer wires
  This multi-layered construction enhances load distribution, bending performance, and wear resistance.
• + FC: The fiber core (FC) provides internal cushioning, improving flexibility, reducing internal wire stress, and extending the rope’s service life in repetitive loading operations.

Applications of 4x36WS + FC Wire Rope in Saudi Arabia’s Industrial Sectors

The unique construction and durability of this wire rope make it highly suitable for the most demanding sectors across the Kingdom:

1. Oil & Gas Drilling and Hoisting

Saudi Arabia’s oil industry relies heavily on durable, high-performance rigging equipment. The 4x36WS + FC wire rope is ideal for:

• Drill line applications
• Mast raising and lowering
• Wireline operations
• Service rig hoisting

Its flexibility and fatigue resistance help handle continuous, high-load cycles without structural compromise.

2. Construction and Infrastructure Development

In major projects across Riyadh, NEOM, and the Red Sea area, tower cranes, hoists, and lifting gear depend on ropes that can handle frequent bending. 4x36WS excels in:

• Tower and mobile crane applications
• Construction hoists
• Material lifts
• Scaffolding hoisting systems

The rope’s smooth winding properties reduce wear on drums and sheaves.

3. Marine and Offshore Platforms

This wire rope is widely used in offshore rigs, shipyards, and ports, especially for:

• Cargo loading and mooring
• Deck winches and lifeboat davits
• Riser tensioning systems

Optional galvanized coating helps resist saltwater corrosion, enhancing rope life on offshore vessels and platforms.

4. Mining and Quarrying

In operations like those in Al Jalamid and Ma’aden’s phosphate projects, material handling and cage hoisting rely on ropes like 4x36WS for:

• Mine shaft lifting
• Conveyor belt drive systems
• Crusher feeder systems

Its ability to handle abrasive environments and constant tension makes it a dependable solution.

5. Logistics and Warehousing

In the logistics hubs of Dammam and Jeddah, this wire rope is used in:

• Overhead cranes
• Automated storage & retrieval systems
• Forklift hoisting mechanisms

With its superior flexibility and reduced wire fatigue, this rope ensures safe, reliable, and long-term operation.

Safe Handling and Maintenance: Our Responsible Approach

At SSTC, we promote safe, responsible, and compliant usage of all our wire ropes. While we provide only quality-tested products, maintaining those products correctly is essential to ensure performance and safety.

Best Practices for Wire Rope Use:

1. Inspection Before Each Use:
   • Look for frayed wires, rust, deformation, kinks, or flat spots.
2. Follow Safe Working Load (SWL):
   • Never exceed the rated capacity.
3. Proper Spooling:
   • Avoid cross-winding and layering errors.
4. Scheduled Lubrication:
   • Maintain internal wire condition by applying lubricant, especially in dusty or corrosive environments.
5. Regular Training:
   • Ensure workers understand proper handling, storage, and inspection procedures.
