Load charts are used to indicate what?

Load charts are essential tools in telehandler operations, providing critical information about the machine's lifting capabilities under various conditions. The correct option highlights that load charts indicate the maximum machine capacity in different lifting zones and configurations. This means that operators can refer to these charts to understand how much weight the telehandler can safely lift at specific distances from the pivot point, as well as how the lifting capacity changes depending on the attachment being used and the orientation of the load.

Understanding the load chart is crucial for safe operation, as exceeding the indicated capacities can lead to tipping, instability, or equipment failure. Operators must be aware of how factors such as the height of lift, extension of the boom, and the configuration of the telehandler (for instance, using stabilizers) affect its overall capacity to ensure safe lifting practices.

The other choices do not provide a complete or accurate description of the function of load charts. For example, those indicating only the maximum engine speed or the telehandler’s weight are not relevant to lift capacities in different configurations, while guidelines for loading procedures pertain to safety protocols rather than the core function of defining the lifting limits of the machine itself.
