HEAVY LIFT

The so-called "heavy indivisible loads" are commonly defined as the weights which cannot be handled by means of the normal gear normally available on board vessels or on the quay, due to their mass or shape. Since the traditional ships are usually equipped with five-ton or maybe even ten-ton cranes or derricks, the handling of a standard twenty-foot container may be treated as heavy lift.

In the meantime, same container on ships equipped with specialist gear, for instance container feeders, will be handled swiftly and as merely routine. So, the definition of "heavy lift" will therefore mainly depend The definition of heavy lift is therefore very much depend on the type of the vessel and the gear installed on board as well as the facilities available on the quayside. The present publication will cover all important aspects of heavy load lifting.

The authors start with the description of the ship types and shipboard cranes and derricks, and then proceed to the stability calculation giving readers brief introduction. Lashing equipment used for heavy lift is dealt with in a separate section. The other sections of the volume are dealing with the loading and lifting operations, lashing cargo and securing it, and associated documentation, such as the Cargo Securing Manual.
