What action should a crane operator take if both fists are in front with thumbs out?

When both fists are in front with thumbs out, this hand signal indicates the instruction to extend the boom sections. This signal is crucial for communicating the desired action clearly and safely during crane operations. Understanding hand signals is essential for effective communication between the crane operator and ground crew, ensuring coordinated movements that prevent accidents and ensure the load is maneuvered as intended.

The other actions, although important in their respective contexts, do not align with the specific signal represented by the fists and thumbs out. For instance, raising the boom or retracting the boom sections would require different hand signals. Similarly, extending the outriggers involves stabilizing the crane rather than adjusting the boom length. Recognizing these signals helps maintain safety and efficiency on site.
