Load spectrum factor
public
Used to determine spectrum loading
Load spectrum factor
$$ K_{p_{crane}} = 0.62999999523163 \: $$
No. of hoist cycles per hour
public
Number of hoist cycles per hour, used in class of utilisation for the crane as a whole.
No. of hoist cycles per hour
$$ cycles_{hour} = 12 \: $$
Hoist hours per day
public
Operating time of hoist motion per day
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 $$ v_{hoist} = 5 \: m / min $$
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 cycles per day
public
Number of hoist motion operating cycles in a day
Hoist motion cycles per day
$$ hoist_{cycles_{day}} = {hoist_{hours_{day}} \cdot cycles_{hour}} $$
Crane operating cycles
public
No. of operating cycles for required service life
No of operating days in a year $$ hoist_{days} = 250 \: days $$ Service life in years $$ hoist_{years} = 25 \: years $$
Total service cycles
$$ crane_{cycles} = {hoist_{cycles_{day}} \cdot hoist_{days} \cdot hoist_{years}} $$
