Which type of sling offers the least flexibility?

Wire rope slings are constructed from steel wires that are twisted together, providing a high level of strength and durability. However, this design results in less flexibility compared to other types of slings. The rigidity of wire rope slings makes them less adaptable in certain lifting situations, especially when wrapping around load contours or fitting into tight spaces. This rigidity can limit their ability to easily conform to the shape of the load, which is a key characteristic of more flexible slings such as synthetic or chain slings.

Synthetic slings, such as those made from nylon or polyester, offer more flexibility and are better suited for applications where conformability to the load is essential. Chain slings, though strong and durable, also have a degree of flexibility that allows them to be manipulated more easily around loads compared to wire rope slings.
