When using a push-loaded scraper, the swell factor increases by what percentage?
Recall how compaction affects material density.
If a scraper's empty weight is 43,944 kg and the load weight is estimated at 32,901 kg, what is the gross weight? How does this compare to the maximum rated load?
Sum the two weights and compare with the manufacturer's specified maximum rated load.
Given a heaped capacity of 23.7 m³ and a swell factor of 0.88, calculate the bank volume for 95% of capacity. How would this affect productivity estimations?
