Which sling can boost closed drums or boxes easily?

The bale sling is specifically designed to handle and lift bundles, closed drums, and boxes efficiently. Its unique configuration allows it to securely grip the items, distributing the weight evenly, making it easier to carry and lift. This type of sling often features multiple loops or hooks that can accommodate different shapes and sizes of cargo, ensuring stability during lifting.

In contrast, the timber hitch is primarily used for securing logs or heavy timber for transport and does not provide the proper means to lift closed containers effectively. The mast head is a term more associated with the rigging and support of a mast rather than a lifting sling, while sheepshanks are utilized for shortening or taking up slack in rope and do not serve as a lifting device. Therefore, the bale sling stands out as the correct choice for lifting closed drums or boxes efficiently.
