What is an example of critical information found on a crane's load chart?

The maximum lifting capacity at various boom angles is crucial information because it allows operators to determine how much weight they can safely lift depending on the configuration of the crane. Load charts are essential documents that help ensure proper and safe operation of the crane by detailing how the crane's lifting capability changes with different boom angles, extensions, and other factors. This information helps prevent overloads, which can lead to dangerous situations such as tip-overs or equipment failure.

In contrast, while color coding for different loads may provide visual guidance, it does not offer the specific quantitative data needed for safe operation. Maintenance schedules and operator guidelines, although important for overall safety and functionality, are not considered critical information directly related to the immediate load-carrying capacity of the crane at that moment.
