The Critical Lift Plan form shall be properly completed, signed, and approved prior to the lift. It shall first be signed by the originator; then signed by the crane operator, and Contractor Rigging Superintendent designated Competent Person.

    It shall then be reviewed and approved by the Rigging Specialist. The Contractor Rigging Superintendent shall physically examine the job site and the equipment to be used prior to giving signature approval to the Critical Lift Plan.

    He shall be physically present to supervise all Critical Lifts. Blanket or multiple use Critical Lift Plans are intended to expedite operations where crane lifts are identical, yet performed on different dates, or where lifts will be performed continuously until the work is completed. Blanket and multiple use Critical Lift Plans may be used for critical lifts using the same model and capacity of crane, working from the same location, to lift the same piece of equipment during different time periods, without having to fill out and sign a new Critical Lift Plan form.

    The same Critical Lift Plan may be used for critical crane lifts, provided: The load configuration is identical, The same lifting equipment and accessories crane, load weight, location, obstructions, work environment, etc.

    Multiple use Critical Lifts Plans are crane lifts using the same model and capacity of crane and location to lift an assortment of different pieces of equipment.

    The same Critical Lift Plan may be used for multiple use critical crane lifts, provided: The most extreme radius, boom length, and load weight of the multiple lifts is used in the calculations, The same crane is used, The Crane Operator and Contractor Rigging Superintendent, who signed the multiple use Critical Lift Plan are used, and A multiple use Critical Lift Plan shall not be valid thirty 30 days from the date of signature by the Contractor Rigging Superintendent.

    After thirty 30 days, a new multiple use Critical Lift Plan shall be obtained. Continue Reading.
