Which type of wire rope construction involves all wires laid in the right-hand direction?

The correct choice highlights the specific construction of wire rope characterized by all wires being laid in the right-hand direction, commonly referred to as right-lay. In this construction method, not only are the individual wires twisted in a right-hand direction, but the overall arrangement aligns with this right-hand lay orientation as well.

Lang-lay refers to the method where the wires or strands are laid in a way that they are more parallel to the central axis of the rope. This construction enhances the rope's flexibility and shock absorption characteristics, making it suitable for specific applications such as lifting or rigging where those properties are vital.

In contrast, various other constructions like left-lay or regular lay involve different arrangements that do not follow this complete right-hand twisting. Understanding this distinction is crucial for riggers when selecting the appropriate type of wire rope for safety and performance in lifting applications.
