Estimate the hourly production in loose volume LCM of a

$2\mathrm{.}68-m3$ wheel loader excavating sand and gravel $($average

material$)$ from a pit and moving it to a stockpile. The

average haul distance is $61m,$ the effective grade is $6\%,$ the

bucket fill factor is $1\mathrm{.}00,$ and job efficiency is $50mi\frac{n}{h}.$
