True or False: The swell factor for push-loaded scrapers is defaulted to increase by 10%.
Consider the impact of additional pressure on the material.
A scraper has a heaped capacity of 30 m³. If loaded to 90% capacity with a swell factor of 0.85, what is the effective bank volume?
Remember to apply the swell factor after calculating the load volume.
If one pusher can support 5 scrapers, what should their combined cycle time for optimal efficiency be if each scraper cycles 8 minutes?
Consider how cycle times overlap to maintain constant work.
