What type of diagram illustrates a crane's full range of boom lengths, jibs, and boom extensions?

The correct answer is that a range diagram illustrates a crane's full range of boom lengths, jibs, and boom extensions. A range diagram is specifically designed to provide a visual representation of the capabilities of a crane, showing how its various configurations can affect its operation. This includes the maximum and minimum boom lengths, the angles at which the boom can operate, and how these factors relate to the crane's lifting capacity at different radii.

This diagram is essential for operators, as it helps them understand the operational limits of the crane under different setups, ensuring safety and efficiency when planning lifts. Understanding the range diagram is crucial for making informed decisions about crane operations, including load placement and ensuring that the crane is being used within its designed specifications.

In contrast, a load rating chart focuses on the maximum weight a crane can safely lift at various boom angles and radii, while a site preparation diagram pertains to the layout and physical arrangements required for safe crane operation. An operation quadrant diagram represents the areas of operation related to lifting capabilities at different angles and distances but does not provide the full details of boom lengths and extensions as depicted in a range diagram.
