Think about what it does after loading.
True or False: The swell factor decreases when using a pusher.
What happens to the material density in the scraper?
A construction site requires you to calculate the total weight of earth moved. If a scraper has a volume of 24.5 loose cubic meters and a swell factor of 0.85, what is the bank volume and the total weight if the unit weight is 1650 kg/m³?
Remember to calculate both volume and then weight.
Assuming a pusher cycle time of 1.5 minutes, what would be the optimal number of scrapers to balance productivity if each operates in a cycle of 8.2 minutes?
Think about how to handle rounding when you get a fraction.
