Software-generated lift plans rely on information such as equipment weight, equipment dimensions, and site conditions to create a scaled drawing of the project site including proposed crane locations, lift area, boom length and angles, and locations of equipment being lifted. Lift plans include necessary details for the crane operation sequence and a plan for job safety.Ĭontractors begin the planning effort by working with a crane company to develop a lift plan. At SEFA, we recognize that there are number of conditions that can make a lift “critical,” such as tight site constraints, people working in lifts next to a suspended load, or awkward loads that might shift during rigging. A critical lift is defined by OSHA as a lift that exceeds 75% of the rated capacity of the crane or requires the use of more than one crane.
