What is the primary purpose of crane signals?

The primary purpose of crane signals is to communicate instructions clearly and effectively between the signal person and the crane operator. This communication is vital to ensure that all actions taken during lifting operations are performed safely and according to plan. A clear set of signals helps prevent misunderstandings that could lead to accidents or injuries on site.

While safety is an important aspect of crane operation, the correct option specifically emphasizes the role of signals in facilitating effective communication. This direct linkage allows the operator and signal person to work in tandem, ensuring that the movements of the crane correspond perfectly with the intentions and needs expressed through the signals.

Other considerations, such as safety during operation, can be seen as a broader goal achieved through effective communication. However, the essence of the function of crane signals lies in their ability to convey precise instructions, ensuring that everyone involved has a shared understanding of actions being taken.
