If ballast configuration changes, what must you consult to ensure the lift limit is correct?

• A. The weather forecast for the day.
• B. The last maintenance report.
• C. The operator's manual from the year it was built.
• D. The manufacturer's load chart for that model and ballast setup.

Answer: (D)

When ballast configuration changes, the lift limit is determined by the manufacturer’s load chart specific to that model and ballast setup. This chart shows the maximum lift capacity at different heights, reaches, and boom angles for the exact ballast configuration you’re using, ensuring you stay within safe stability limits. Other sources don’t reflect the precise combination of machine model and ballast you have, so they can’t give you the correct, current limit: weather forecasts affect ground conditions but not the machine’s rated lift capacity, maintenance reports cover service history rather than capacity, and an older operator’s manual may be outdated for your setup. Trust the manufacturer’s load chart for the exact limits of that model with that ballast.
