* Stall Gradeability Limit
** Equivalent Grade = Grade + Rolling Resistance

EVW = Empty Vehicle Weight
GVW = Gross Vehicle Weight

All applications must be approved by GE Transportation, Mining - Erie, PA

To determine truck speed at a specific equivalent grade and weight, start with the truck weight, trace down to the specific equivalent grade, and from that intersection, move horizontally until you reach the motoring curve. At the intersection, trace down to determine the corresponding truck speed.
