If a digger derrick has a work platform, where is the jib capacities chart normally located?

The jib capacities chart is typically located on the platform of the digger derrick because it serves as a critical reference for the operator while working at height. This placement ensures that the operator has immediate access to essential information regarding load capacities and safe working limits, which is crucial when performing tasks that require precision and safety. By keeping the chart on the platform, the operator can easily view it during operation without having to divert their attention to other areas of the machinery, helping to promote safety and efficiency in the work environment.

In contrast, having this information on the control panel or under the operator seat would not provide the same level of accessibility during operation. Similarly, placing the chart on the lift arm would not allow for easy viewing while using the equipment. Therefore, the platform's location is the most logical and safe choice for the jib capacities chart.
