3.2. Fixed & Variable Time

Try these first

1. 1.

   What is a bucket fill factor?

   Hint

   Think about how different materials might fill a bucket.

2. 2.

   Define static tipping load.

   Hint

   Remember the risk of tipping!

3. 3.

   What is the purpose of a bucket fill factor?

   • To increase load capacity
   • To adjust the rated capacity based on material type
   • To determine tipping load

   Hint

   Remember, it changes with the material type.

4. 4.

   True or False: Fixed time includes the time taken for travel between locations.

   • True
   • False

   Hint

   Think about what fixed means.

5. 5.

   Calculate the production rate of a wheel loader with a heaped capacity of 3.5 m³, fill factor of 80%, a fixed cycle time of 25 seconds, and unit weight of 1500 kg/m³ for the material.

   Hint

   Remember to convert seconds into hours for the production calculation.

6. 6.

   If a loader's tipping load is 10,000 kg and it exceeds the load by 20%, what are the safety implications?

   Hint

   Consider how safety protocols are essential for operational management.
