What are lifting lugs?

Lifting lugs are specifically designed components that are attached to a steel plate (or other structures) to provide a secure point for lifting. They are typically eyelets that are welded onto the material, ensuring that heavy loads can be safely and effectively hoisted using appropriate lifting equipment such as cranes or hoists. The design of lifting lugs allows them to distribute the weight of the load evenly and minimize stress on the structure during lifting operations.

The other options are clearly related to different uses or types of materials in industrial applications. For instance, rigging materials that clamp onto surfaces are used for securing loads, pilot bits are tools for drilling, and devices for aligning plates assist with maintaining structural integrity during assembly. However, none of these functions are directly related to the specific role that lifting lugs play in lifting operations.
