4. Balancing Interdependent Machines

Try these first

1. 1.

   What does gravimetric capacity refer to?

   Hint

   Think about the manufacturer's specifications.

2. 2.

   Why is it important to check the load weight against the gravimetric capacity?

   Hint

   Consider the consequences of exceeding limits.

3. 3.

   What is the gravimetric capacity?

   • Maximum safe load of a machine
   • Total weight of materials
   • The speed at which materials are processed

   Hint

   Think about safety limits within machine operations.

4. 4.

   True or False: Overloading a truck increases productivity.

   • True
   • False

   Hint

   Consider long-term effects of overloading.

5. 5.

   A project requires a loader operating at 4 bucket loads for a truck that has a capacity of 8.5 m³, adjusted for a 0.85 fill factor. Calculate the number of trucks needed if the excavator has a cycle time of 1.5 minutes and the truck cycle time is 30 minutes.

   Hint

   Adjust the truck capacity and use the provided cycle times.

6. 6.

   Discuss the long-term effects of continuously overloading a truck on operational costs and productivity. Use specific cost percentages if applicable.

   Hint

   Reflect on the implications beyond immediate productivity gains.
