What is a swing-away lattice extension commonly referred to as?

A swing-away lattice extension is commonly referred to as a fly. This terminology is used in the context of cranes and lifting equipment where the fly serves to extend the reach of the main boom or provide additional height. The fly assists in achieving greater lifting capabilities and versatility while maintaining stability during operations.

In addition, a fly's design allows it to pivot or swing away from the main structure, facilitating easy maneuverability and placement of loads, which is essential in construction and heavy lifting scenarios. Understanding the function and terminology associated with different crane components is crucial for safe and efficient operation in the field.
