3.4. Estimating Variable Time

Try these first

1. 1.

   What is a bucket fill factor?

   Hint

   Think about different materials and their filling abilities.

2. 2.

   Define tipping load.

   Hint

   Consider stability while operating machinery.

3. 3.

   What defines the bucket fill factor?

   • It is constant for all materials
   • It varies based on material type
   • It is not used in calculations

   Hint

   Consider how the material alters the ability to fill a bucket.

4. 4.

   The tipping load indicates safety in operation?

   • True
   • False

   Hint

   Is this related to how we ensure safe operation of heavy machinery?

5. 5.

   A loader with a tipping load of 14,000 kg is used with a fill factor of 0.85 and must not exceed the operating limit. Calculate the maximum allowed load in the bucket for safety.

   Hint

   Use the tipping load limits to determine safety values.

6. 6.

   If a loader has an effective bucket capacity of 3.0 m3 and a unit weight of material handled is 1200 kg/m3, how much will the loader be able to carry?

   Hint

   Consider the volume and weight relation for your calculations.
