Hoist hours per day
public
Operating time of hoist motion per day
Input
No. of hook strokes per cycle
$ hook_{cycles} = 4 \: $
Hook travel
$ hook_{travel} = 4 \: m $
Operating hours per day
$ hours_{operating} = 8 \: h $
Hoist speed
$ v_{hoist} = 5 \: m / min $
Result
Hoist motion hours per day
$$ hoist_{hours_{day}} = {{( hook_{cycles} \cdot hook_{travel} \cdot cycles_{hour} \cdot hours_{operating} ) \over \left({ v_{hoist} \cdot 60 }\right)}} \:, h $$

hoist_{hours_{day}} = ( hook_{cycles} * hook_{travel} * cycles_{hour} * hours_{operating} ) / ( v_{hoist} * 60 )
