The backhoe is mainly used for deep excavations? (True/False)
Consider what type of excavation it is used for.
Given a project needing extensive excavation of hard material, how would you decide between using a front shovel or a backhoe, considering productivity metrics?
Think about the characteristics of both machines.
Calculate the optimal productivity for a front shovel with a maximum digging height of 5 meters and actual cutting height of 3 meters. Apply the lifting time, dumping time, and return swing time.
Evaluate how height affects the cycle time in the operation.
