1. Bucket Ratings and Capacity

Try these first

1. 1.

   What does heaped capacity refer to?

   Hint

   Think about how a bucket can be filled above its rim.

2. 2.

   What impact does the type of material have on bucket fill factor?

   Hint

   Consider the differences in particle size and shape.

3. 3.

   What is the heaped capacity of a loader?

   • The volume of water it can hold
   • The maximum material volume that can be heaped in the bucket
   • The weight limit of the bucket

   Hint

   Think about what it means to fill something up.

4. 4.

   Is the bucket fill factor constant for all materials?

   • True
   • False

   Hint

   Consider examples like sand and gravel.

5. 5.

   A loader has a rated bucket capacity of 1.5 m³. If the fill factor for gravel is 75%, what is the actual load volume?

   Hint

   Consider how to apply the fill factor to the rating.

6. 6.

   If your loader tips at 6,000 kg, what’s the maximum allowable load for a wheel-mounted loader to maintain safety?

   Hint

   Use the safety factor percentages discussed.
