In technical parlance, the American Society of Mechanical Engineers (ASME) defines a below-the-hook (BTH) lifting device as "a device employed for the purpose of affixing a load to a hoist. This apparatus encompasses constituent elements including slings, hooks, and rigging hardware..." In a more accessible context, a BTH lifting device essentially operates as a specialized mechanical tool designed for integration with cranes or analogous lifting machinery. Its primary function revolves around the adept capture and securement of a load, facilitating its safe and controlled transportation from one spatial point to another. In essence, this equipment serves as an intermediary link, augmenting the crane's ability to delicately yet robustly lift and relocate substantial loads by providing a reliable means of attachment and stability.
