4.1. Formula for Productivity

Try these first

1. 1.

   Define the term 'bucket rating'.

   Hint

   Think about what the manufacturer provides regarding volume.

2. 2.

   What is the purpose of the bucket fill factor?

   Hint

   Consider why you'd need to change the bucket's rated capacity.

3. 3.

   What is the purpose of the bucket fill factor?

   • To calculate static tipping load
   • To adjust rated bucket capacity based on material
   • To determine loader speed

   Hint

   Think about how different materials fill a bucket.

4. 4.

   The static tipping load refers to?

   • True
   • False

   Hint

   Consider what tipping implies in loader operations.

5. 5.

   A loader has a bucket rated at 1.5 m³ and a fill factor of 70%. Calculate the productivity per hour if the total cycle time is 40 seconds and job efficiency is 30 minutes.

   Hint

   Convert seconds to hours for efficiency and apply the fill factor correctly.

6. 6.

   If a wheel loader operates with a maximum static tipping load of 12,000 kg, what is the maximum allowable load in the bucket to maintain a safe operational percentage of 50%?

   Hint

   Always consider the safety factor relevant to tipping load.
