HORSEPOWER- INCLINE/DECLINE - SLIDER BED
BELT CONVEYORS (INCLINE OR DECLINE)
+ Product (Total Live Load)
+ Belt Weight (See Belt Weights Chart)
+ Drive Weight (250#)
= Subtotal
x .30 Friction Factor
= Subtotal
+ (Actual Live Load on Incline Portion of
Conv. x Sine of Incline--See Sines Chart)
= Subtotal
x 1.25 (25% Contingency Factor)
= Effective Belt Pull
x Speed of Conveyor
÷ 33,000 Horsepower Factor
÷ .95 Chain Reductions
÷ .85 GRE / Reducer Losses
