Should the calculated weight be measured in excess of 50 tons, or classified as critical (exceeds 90% of the crane capacity chart), a detailed rigging plan, including supporting calculations, will need to be developed for review and acceptance prior to lift. Shackles, hoist rings, and other hardware.When calculating the total weight of the load, calculations used must account for every piece of lifting gear involved in the lift. Type of lifting slings, rigging hardware and below-the-hook devices if required.Examples of the things which are affected includes: This should be determined in the early planning stages of a lift, as everything else about the overhead lift will need to account for the weight of the load. One of the very first things to do prior to lifting a load is determine the total weight of the load. Selection of the appropriate rigging gear to suit lifting points.

Location and quantity of approved lifting lugs or lifting points.

Overall maximum dimensions of the load.

Location of the load’s center of gravity.

The items listed below are the points of consideration for the decision maker.

Any party who has the expertise and relevant knowledge can create the lifting plan. The Lifting Plan is a set of plans developed for use in any crane lifting operation. 8 Steps to consider when drafting a lifting plan There are a few steps to consider when drafting a Lifting Plan. Thus, with lives at stake during such high-risk operations, it is of paramount importance that Lifting Supervisors is confident enough to take charge of the lifting plan, while the lifting team is clear and familiar with the steps present in the Lifting Plan. Lifting operations are often hazardous processes, due to the involvement of many large machinery and heavy loads.
