Abstract
System, including methods and apparatus, for mechanically moving components with lifting machinery. In some embodiments, the system may comprise a lug mounted to a component, and a clasp. The clasp may include a body configured to receive the lug. The clasp also may include a gate mechanism configured to support the body when the clasp is supported by lifting machinery, and to move with respect to the body between (a) an open position that allows removal of the lug from the body when the gate mechanism is not supporting the body and (b) a closed position that prevents removal of the lug from the body when the gate mechanism is supporting the body.
