CABLE LAID WIRE ROPE GROMMET /ENDLESS SLING

Construction and specification

General information on wire ropes

In the above example, each individual wire is arranged around a central wire to form a 7-wire strand. Six of these strands are formed around a central core to make a wire rope. The rope is specified as 6×7 (6/1) – i.e. six strands each of seven wires.

The specification of a wire rope type – including the number of wires per strand, the number of strands, and the lay of the rope – is documented using a commonly accepted coding system, consisting of a number of abbreviations. This is easily demonstrated with a simple example. The rope shown in the figure “Wire rope construction” is designated thus: 6×19 FC RH OL FSWR.

• 6 – Number of strands that make up the rope
• 19 – Number of wires that make up each strand
• FC – Fibre core
• RH – Right hand lay
• OL – Ordinary lay • FSWR – Flexible steel wire rope

Each of the sections of the wire rope designation described above is variable. There are therefore a large number of combinations of wire rope that can be specified in this manner.

Applications:

1. Lifting and Rigging: Ideal for heavy lifting and rigging applications, providing strength and durability for secure load handling.
2. Marine and Offshore: Suited for maritime and offshore operations, enduring harsh conditions and resisting corrosion.
3. Construction: Essential in construction projects for hoisting materials, ensuring stability and safety.
4. Mining: Reliable in mining environments, withstanding abrasive conditions and heavy loads.
5. Material Handling: Versatile for various material handling tasks, providing a reliable means of lifting and securing loads.

How to Use:

1. Inspect Regularly: Before each use, visually inspect the grommet or sling for any signs of wear, damage, or deformities. Replace if any issues are detected.
2. Proper Attachment: Ensure correct attachment to the load and lifting equipment, following recommended procedures and guidelines.
3. Load Calculation: Determine the weight of the load to be lifted and choose a grommet or sling with an appropriate Safe Working Load (SWL).
4. Consider Environmental Factors: Adapt usage based on environmental conditions, such as exposure to moisture, chemicals, or extreme temperatures.
5. Adherence to Guidelines: Follow industry standards and regulations for the safe and effective use of cable-laid wire rope grommets or endless slings.
