What is the purpose of a load chart in crane operations?

• A. It shows the maximum load at different radii and boom configurations
• B. It shows the crane's maintenance schedule
• C. It shows the load chart values for various configurations
• D. It documents operator training

Answer: (B)

The load chart communicates safe lifting capacity for a crane across different geometries. It shows the maximum load the crane can lift at each radius and with each boom configuration (length, angle, and any jib extension). This allows you to choose a setup that stays within the crane’s rated capacity, preventing overloads during a lift. Maintenance schedules or training documentation aren’t part of what a load chart provides, and while the chart does present capacity values for various configurations, its main purpose is to guide safe lifting by indicating the maximum permissible load for each configuration.
