Can a hoist be hung from a wire rope sling without a shackle installed, if the diameter of the hook is equal to or greater than the diameter of the sling?

The practice of hanging a hoist from a wire rope sling without a shackle can be safe under certain conditions, particularly if the diameter of the hook is equal to or greater than the diameter of the sling. This suggests that the hook can adequately secure the sling without compromising the integrity of either component. A hook that matches or exceeds the sling's diameter helps ensure that there is sufficient strength and a proper fit to prevent slippage during lifting operations.

When the hook is appropriately sized, it can provide a secure connection that minimizes the risk of accidental disconnection or failure during use, especially if the load remains within acceptable limits. However, it's essential to consider factors such as load weight, the condition of the sling and hook, and the nature of the lift.

In contrast, the other choices invoke scenarios that overlook these considerations. For instance, stating it is always unsafe does not account for the specific circumstances where the hook's size could provide a safe connection. Similarly, claiming it is safe only for light loads does not accurately reflect the fact that when conditions permit, heavier loads could also be handled safely. Lastly, simply suggesting it depends on conditions without addressing the sizing provides an unclear guideline for safe practices. Thus, understanding the relationship between the sizes of the
