We also see some lifting-related definitions. First, in this post, we will talk about safe crane lifting operations, and the procedure according to SABIC (Saudi Arabia).īefore projecting a lifting plan with a safety factor, firstly, we will see how to establish the preventive measures for crane lifting hazards and the correct work methods that must be applied by all the lifting crew members involved in the lifting activities. Once we have all this information, we will explain how to make the lifting plan for critical lifting operation step by step in this blog. This plan explains the details of the Boom length to be used, Boom angle and Lift height. The Lifting Plan is generally carried out by rigger level 1 by mathematical calculation among the Weight of the object, Rigging Weight, contingency weight and Crane capacity at the working radius with the help of a load chart. Crane Lift Plan Requirements to carry out critical crane lifting operations, due to their complexity, it is necessary to make a Lifting Plan to know the safety factor.
