Features
As a mechanical lifting tool, the hook assembly is normally suspended on the wire rope of the lifting mechanism by means of pulley blocks and other components. The hook assembly includes two types i.e. the one with single hook and the one with two hooks, from the point of view of structure; or forged hook and laminated hook type according to the manufacturing technique. The tool with single hooks is always used for lifting the objects less than 80 t while that with double hooks used for the cases that need to lift the heavier objects with symmetrical force. The laminated hook features better safety performance, but its dead weight is higher, thus it is always installed on the crane with large lifting, which is suitable for cranes, crown block and bridge crane used in docks, factories, mines and petrochemical industries
