What is meant by the term "blind lift" in crane operations?

The term "blind lift" in crane operations specifically refers to a situation where the operator cannot see the load due to obstructions. In such scenarios, it is vital to have effective communication between the operator and the signal person, as the operator relies heavily on signals to ensure safe lifting and movement of the load. This understanding is crucial because without visibility of the load, there is a higher risk of accidents if signals are not clearly communicated.

The other options do not accurately capture the essence of a blind lift: performing a lift with a clear view of the load, using cameras, or lifting very light loads without assistance involve situations where visibility and control are not compromised, which is not the case in a blind lift. This emphasizes the importance of recognizing potential hazards associated with obstructions when planning and executing lifting operations.
