What is the SWL of an 8mm diameter flexible steel wire rope (FSWR)?

The Safe Working Load (SWL) of a flexible steel wire rope is determined through the rope's diameter and construction characteristics. For a flexible steel wire rope, a common rule of thumb is to use a standard ultimate tensile strength from which the SWL is derived by applying a suitable safety factor.

In this case, an 8mm diameter flexible steel wire rope typically has an SWL of 512 kg, reflecting a general industry standard. This calculation often considers the material properties, the number of wires in the rope, and the construction method, which all influence the rope's strength and load capacity.

Understanding the basis for these figures is essential. The SWL indicates the maximum load that can safely be applied to the rope without risking failure. Using the standards in practice helps ensure safety, especially in high-stress environments where equipment is subjected to powerful forces. Safety factors are vital since they account for variability in load distribution, potential wear and tear, and dynamic forces during operation.

The other provided figures do not align with the common specifications recognized for an 8mm flexible steel wire rope, which is why they are not the correct answers.
