4. Estimating Productivity

Try these first

1. 1.

   What is the fill factor for a material that fills 90% of the bucket capacity?

   Hint

   Fill factors are expressed as a fraction of the total capacity.

2. 2.

   Define static tipping load.

   Hint

   Consider safety and operational limits regarding tipping.

3. 3.

   What is the bucket fill factor?

   • A measure of bucket weight
   • A correction factor for capacity
   • A stability indicator

   Hint

   Think about how different materials may affect filling capacity.

4. 4.

   True or False: The allowable operating load for wheel loaders is 50% of the static tipping load.

   • True
   • False

   Hint

   Consider safety guidelines mentioned in the section.

5. 5.

   A loader with a static tipping load of 10,000 kg is operating. If a construction company plans to load the bucket with a heavy material weighing 2,000 kg/m³, what is the maximum volume of material they can load to ensure stability?

   Hint

   Use the tipping load and consider the weight per volume.

6. 6.

   Calculate how many hours a loader can operate in a day if its productivity is 4,000 kg per hour and a project requires moving 20,000 kg of material.

   Hint

   Divide total material to move by hourly output for hours needed.
