1.5. Dump Time

Try these first

1. 1.

   What is the formula for calculating cycle time?

   Hint

   Think about what each component stands for.

2. 2.

   Can dump time be influenced by the type of material being handled?

   Hint

   Consider how easy it is to unload different types of soil.

3. 3.

   What components are included in cycle time?

   • Only fixed time components
   • Only variable time components
   • Both fixed and variable time components

   Hint

   Remember the equation provided in the section.

4. 4.

   True or False: Loading beyond 85% capacity can lead to increased productivity.

   • True
   • False

   Hint

   Think about how materials interact when too much is packed.

5. 5.

   A construction site has scrapers with a cycle time of 4.5 minutes. If the project shifts to a new area that increases haul time by 30 seconds, what is the new cycle time?

   Hint

   Consider how each increment in time affects the overall cycle.

6. 6.

   If a loader scrapes 100 tons in an hour but increases the payload by 100% without modifying the loading efficiency, what will be the effect on the loading time and the production rate?

   Hint

   Analyze the implications of load growth on the overall time.
