A multi-crane lift requires which of the following?

  1. A critical lift plan

  2. Coordination between operators

  3. Reduction of gross capacity by 10%

  4. A single operator for all cranes

The correct answer is: A critical lift plan

A multi-crane lift necessitates a critical lift plan due to the complexity and risks involved in using multiple cranes simultaneously. Such a plan outlines specific procedures to ensure safety, proper coordination, and effectiveness during the lift. It addresses critical factors such as the weight of the load, the capacity of each crane, the rigging methods, and any potential hazards in the environment. This comprehensive planning is essential to mitigate risks associated with multi-crane operations, including load shifting, potential collisions, and maintaining stability throughout the lift. The other choices, while relevant to certain aspects of crane operations, don't encompass the full scope of what is required for a multi-crane lift. Coordination between operators is indeed vital, but it is a part of the broader critical lift plan rather than a standalone requirement. Similarly, reducing the gross capacity by 10% may apply in specific scenarios, but it is not a universal requirement for all multi-crane lifts. Having a single operator for all cranes is impractical and not typically safe, as each crane should be operated independently to ensure focused and effective control during the lift. The critical lift plan integrates all these elements, making it imperative for safe multi-crane operations.
