What type of movement is allowed by a swivel hoist ring?

The correct answer identifies the movement allowed by a swivel hoist ring as rotational. Swivel hoist rings are specifically designed for lifting and moving loads in a way that allows the lifted object to rotate around the vertical axis of the hoist ring. This is essential in many lifting operations because it provides the flexibility to align the load with the intended direction of movement without having to reposition the hoisting equipment or the load itself.

The design of a swivel hoist ring includes a mechanism that allows it to pivot freely, which eliminates the risk of the load becoming twisted or unbalanced during lifting. This rotational capability is particularly valuable when maneuvering loads in tight spaces or when positioning them accurately.

Other potential types of movement, such as linear or diagonal, are not characteristic of a swivel hoist ring's operation. Instead, its primary functionality is to facilitate smooth and controlled rotational movement, ensuring safety and efficiency in lifting operations.
