Gravity torque only needs to be considered when the belt is not mounted horizontally. It is a positive number when the load is moved upward, and a negative number when the load is moved downward. Equation 3: T GRAVITY (oz-in.) = rW LOAD sin ϕ In our example, the conveyor is not inclined, therefore ϕ = 0°, which means that T GRAVITY = 0. T
