What is the purpose of using a hoist in rigging?

The purpose of using a hoist in rigging is primarily to lift heavy materials. Hoists are mechanisms equipped with gears, pulleys, or chains that are specifically designed to facilitate the lifting of substantial loads that would otherwise be difficult or unsafe to move manually. Hoists provide mechanical advantage, making it easier to raise and lower heavy items with precision and control. This capability is essential in various applications, particularly in construction, manufacturing, and maintenance environments, where heavy lifting is a common requirement.

Each of the other options relates to important rigging practices but does not capture the primary function of a hoist. For instance, while securing a load is crucial in rigging to prevent accidents, it is not the core purpose of a hoist. Similarly, tensions in ropes and the attachment of rigging components are vital processes within rigging operations, but these tasks may be accomplished through other tools and techniques rather than specifically through the function of a hoist.
