This Standard specifies general requirements for the design, testing, marking and correct care and use of lifting devices that can be fitted directly or indirectly to the hook or any other coupling device on a crane, hoist or winch, as defined in AS 2549, without affecting its integrity. This Standard does not cover lifting equipment such as slings, lifting gear, workboxes and items covered by other Australian Standards.
