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.

Retarding Performance
To determine performance, read from
Gross Weight down to % Effective Grade.
Effective Grade equals actual % favorable
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. Retarding effect
on these curves represents full application of
the retarder.
