Gradeability/Speed/Rimpull
To determine performance, read from
Gross Weight down to % Total Resistance.
Total Resistance equals actual % grade plus
1% for each 10 kg/metric ton (20 lb/ton) of
Rolling Resistance. From this point, read
horizontally to the curve with the highest
attainable speed range. Then, go down to
Maximum Speed. Usable Rimpull depends
on traction available.
