Where the qualified person determines that engineering expertise is needed for the planning, the employer must ensure that it is provided. The plan must be developed by a qualified person and be designed to ensure that all requirements of this standard are met. Accordingly, when more than one crane/derrick is used to support the load, a plan must be developed and implemented.
It is particularly important to determine how the weight of the load will be distributed among the multiple pieces of equipment during all phases of the operation to ensure that all are operated within their rated capacities. Lifts in which more than one crane or derrick is used require careful planning and precise coordination.
