1. 1.

   What is the fill factor and why is it important?

   Hint

   Think about how different materials fill a bucket.

2. 2.

   Define static tipping load.

   Hint

   Consider what happens to balance when too much weight is added.

3. 3.

   What is meant by bucket fill factor?

   • A. The total capacity of the bucket
   • B. A correction applied based on material
   • C. The speed of loading

   Hint

   Focus on how different materials affect the filling capacity.

4. 4.

   True or False: The static tipping load is determined by the manufacturer under dynamic conditions.

   • True
   • False

   Hint

   Think about how tests are conducted to ensure safety.

5. 5.

   A loader has a bucket capacity of 3.5 m³. The bucket fill factor for crushed stone is 0.75, and the loader weighs 12,000 kg empty. If the manufacturer states the static tipping load is 9,000 kg, what is the maximum allowable load for safety?

   Hint

   Remember to factor in the safety percentage.

6. 6.

   Estimate how much time a loader will take if the haul distance is 50 meters, and it takes 15 seconds to fill the bucket. The maximum speed loaded is 5 m/s, and the empty trip is 8 m/s.

   Hint

   Calculate each segment of the operation to derive total time.
