Gradeability/Speed/Rimpull

To determine gradeability performance: Read from grossweight down to the percent of total resistance. Total resistanceequals actual percent grade plus rolling resistance. As a generalguide use 2% for rolling resistance in underground applicationsor refer to the Caterpillar Performance Handbook. From the

total resistance point, read horizontally to the curve withthe highest obtainable gear, then down to maximum speed.Usable rimpull will depend upon traction available andweight on drive wheels.
