How to Use This Calculator

Enter the belt length and conveyor incline angle.
Set the material load in pounds per foot and belt weight.
Input drive efficiency and friction coefficient.
Review effective belt tension (Te), maximum belt tension (T1), and slack-side tension (T2).
Use maximum belt tension to verify belt rating is adequate for the application.
