Define what a scraper does in construction.
Consider its role in material handling.
What is cycle time?
Think of the entire operation process.
What is the primary function of scrapers in construction?
Think about the materials typically handled by these machines.
True or False: Having more scrapers always reduces production costs.
Consider the relationship between cost, efficiency, and productivity.
Given that four scrapers yield a production of 500 bcm per hour and the cost per cubic meter is ₹50. Calculate the new cost per cubic meter if the number of scrapers is increased to six and output increases by 20%.
Think of how the productivity increases impacts the overall cost.
If the hourly cost of operating a scraper is ₹4500 and a pusher is ₹5600, calculate the total operational cost if you are using 5 scrapers and 1 pusher for one hour.
Break down each component of the operational cost for clarity.
