This training package illustrates and explains the many different ways to lift a load by cranes, hoists and winches during the varied operations seafarers are involved in when moving provisions, machinery and cargo.

It establishes that it is most important to know the weight of the load so that the correct weight load limit for each of the shackles, hooks, clamps and slings employed in the lift can be determined. If the weight is unknown, the package explains the method of calculating it for both regular shaped and irregular shaped objects.

The method of selecting the various shackles, hooks, blocks and slings is shown and their range of configuration and material is illustrated, including steel wire, rope, webbing etc.

The video package then discusses and illustrates the different hitches that are normally employed in typical lifting situations in the engine room and on deck. These include the vertical hitch, bridal hitch, the basket hitch and the choker hitch. In each case graphic illustrations are provided to show the various forces and the angles at which they prevail which affects the weight load ratings of all the rigging involved.

Finally, there are a number of special cases discussed and illustrated, for example, lifts which involve tandem application of rigs; rigs which lift through openings; unusual hitching and multiple hitching. The video places great emphasis on the need for operators of lifting equipment to undergo thorough training.
