772 Off-Highway Truck specifications
To determine gradeability performance: Read from gross
weight down to the percent of total resistance. Total resistance
equals actual percent grade plus 1% for each 10 kg/t (20 lb/ton)
of rolling resistance. From this weight-resistance point, read
horizontally to the curve with the highest obtainable gear, then
down to maximum speed. Usable rimpull will depend upon
traction available and weight on drive wheels.
