ITEM NUMBER:  
kipsTotal load, includes the weight of vessel, trays, insulation, piping, rigging, etc
degAngle of the left sling. Use the smallest sling angle if CG is off center
Number of parts of lift sling at each end of bar, ie, a doubled sling is two parts
inHorizontal distance, bearing to bearing on a duplex crane hook
inHorizontal distance from the CG to the centerline of the left vertical lift sling
inHorizontal distance from the CG to the centerline of the right vertical lift sling
SELECT: Lift sling type, diameter, and SWL. Program will prompt for larger capacity sling if required
SELECT: Pipe diameter and schedule

OUTPUT:
inLength of the left lift sling, centerline of the bar to bearing on the hook
inLength of the right lift sling, centerline of the bar to bearing on the hook
inLength of the left support sling, centerline of lug hole to bearing on hook
inLength of the right support sling, centerline of lug hole to bearing on hook
inRigging height, centerline of the bar to bearing on hook
degAngle of the right sling
kipsTension in the left lift sling above the bar
kipsTension in the right lift sling above the bar
kipsTotal lift sling capacity at each end of the bar, ie, number of parts*SWL
kipsMaximum tension in the support slings
kipsCompression in the bar due to the influence of the lift slings
kip-inMoment due to compression force times the eccentricity, left end of bar
kip-inMoment due to compression force times the eccentricity, right end of bar
kip-inMoment due to the deflection of the bar due to self weight
kip-inMoment due to the self weight of the bar
kip-inNet bending moment, left end of barA minus value indicates the bar
kip-inNet bending moment, right end of baris being bowed up at the center
