If a bulldozer’s ideal productivity, as per manufacturer's curve, is 500 m³/hour, and correction factors for operator skill (0.85) and visibility (0.9) must be applied, what is the actual productivity?
💡 Hint: Multiply the ideal productivity by both correction factors sequentially.
A bulldozer with a total cycle time of 10 minutes operates at a job efficiency of 25 minutes per hour. How many cubic meters can it potentially move if the ideal production rate is set at 400 m³/hour?
💡 Hint: Adjust the ideal production rate to reflect the hourly operation time.
