An excavator is loading poorly blasted rock from a $8-$ft high surface. What is the

calculated production in LCY$/$hr$?$

$$ Bucket: $8$ LCY heaped capacity

$85\%$ fill factor for poorly blasted rock

$$ Maximum rated digging height of $32$ ft$.$

$$ Optimum height is $(1)/(2)$ max height

$$ The swing angle used is $75\backslash$deg

$$ Ideal cycle time is $30$ seconds

$$ Efficiency is $45$ minutes$/$hour
