2. Payload Weight and Stability

Try these first

1. 1.

   What does bucket rating refer to?

   Hint

   Consider what manufacturers provide about capacity.

2. 2.

   Why is the bucket fill factor necessary?

   Hint

   Think about different materials' filling abilities.

3. 3.

   What is a bucket fill factor?

   • A measurement of weight
   • A correction to bucket volume
   • A type of loader

   Hint

   Think about adjustments required for different materials.

4. 4.

   True or False: The static tipping load is the maximum weight a loader can safely carry.

   • True
   • False

   Hint

   Consider safety guidelines provided by manufacturers.

5. 5.

   A loader with a 4.0m³ capacity bucket and a fill factor of 70% has a static tipping load of 15,000 kg. If the unit weight of the material is 1,500 kg/m³, what weight can be safely loaded in the bucket?

   Hint

   Calculate the weight first and compare with tipping limits.

6. 6.

   Calculate the total cycle time for a loader operating with a fill factor of 75%, a rated capacity of 3.2 m³, and fixed cycle time of 20 seconds. If operational time per hour is 40 minutes, what is the production rate?

   Hint

   Remember to convert units to match and apply the full formula.
