What type of information should be clearly posted and readily available to the operator?

The type of information that should be clearly posted and readily available to the operator includes labels for each function of the crane. This is crucial because clear labeling enables the operator to quickly identify and understand the controls and functions of the equipment they are operating. It serves as a visual aid that can help prevent operational errors, enhancing safety during crane operation. Each label should provide clear and concise information about what each button, lever, or switch does, ensuring the operator can respond effectively to various situations they may encounter on the job site.

While emergency procedures, maintenance schedules, and operator training materials are also important, they may not be as immediate or crucial to the operator's ability to control the crane during operation. Emergency procedures can provide guidance in critical situations, but they are not as frequently referred to during normal operations as function labels. Maintenance schedules and operator training materials are more suited for reference outside of immediate operational needs and are essential for upkeep and knowledge but do not directly aid in the operational control of the crane like clearly labeled functions do.
