What are the three elements contained in each series of voice signals for crane operations?

The correct answer includes three essential elements often used in voice signals during crane operations: Function and Direction, Distance and Speed, and Function Stop.

Understanding each of these components is crucial for efficient and safe crane operation.

"Function and Direction" refers to the specific task the crane operator is to perform, such as lifting or lowering the load, along with the direction of movement. This ensures clarity and precision in conveying the operator's intent.

"Distance and Speed" provide additional parameters that help to communicate how far the load should be moved and at what speed. This is particularly important for maintaining safety and control when working with heavy loads.

Lastly, "Function Stop" signals the operator to halt movement, which is vital for preventing accidents and ensuring the safety of workers on the site.

Together, these elements create a clear and concise communication protocol that enhances coordination between the crane operator and the personnel on the ground, promoting a safer working environment.
