4.2.1. When Trucks are Less Than the Balanced Number

Try these first

1. 1.

   What is gravimetric capacity?

   Hint

   This capacity is crucial for preventing overload.

2. 2.

   How do you calculate the payload of a truck?

   Hint

   Remember to multiply the volume by density.

3. 3.

   What does gravimetric capacity refer to?

   • The total weight
   • Maximum safe load
   • Machine age

   Hint

   Think about what it signifies for machine operation.

4. 4.

   True or False: An overloaded truck can cause excessive wear on tires.

   • True
   • False

   Hint

   Consider the impact of weight on tire performance.

5. 5.

   A loader operates with a 2.5 m3 bucket and a cycle time of 1 minute. If the truck has a capacity of 10.5 m3 and takes 40 minutes for a full cycle (loading + hauling + unloading + return), determine the optimum number of trucks needed for balance.

   Hint

   Don’t forget to factor in the fill factor for actual buckets!

6. 6.

   Evaluate the implications of using heavier materials versus lighter ones in a construction context on machinery costs and efficiency.

   Hint

   Analyze operational differences in machine load outputs.
