What does "reeving" mean in the context of rigging?

In the context of rigging, "reeving" specifically refers to the process of threading a rope or cable through pulleys or similar devices. This action is crucial because it affects how a load is lifted, moved, or controlled. Proper reeving creates mechanical advantages, enabling more efficient lifting of heavy loads while ensuring safety and stability in rigging operations. The arrangement of the rope or cable around the pulleys can significantly impact the load distribution and the overall effectiveness of the rigging setup.

The other options pertain to different actions or considerations in rigging. Measuring load weight refers to the process of assessing how much weight is being lifted, securing loads involves methods of fastening items to prevent movement, and adjusting height relates to modifying the elevation of rigging equipment for specific tasks. While these elements are essential in rigging, they do not define the action of reeving.
