CALCULATING
HORSEPOWER - CHAIN DRAG
CHAIN DRAG
+ Product (Total Live Load)
+ Chain Weight (see below)
+ Drive Weight (100#)
= Subtotal
x .20
x 1.25 (25% Contingency Factor)
= Effective Chain Pull
x Speed of Conveyor
÷ 33,000 Horsepower Factor
÷ .95 Chain Reductions
÷ .85 GRE / Reducer Losses
= Horsepower
