Grade distance: Continuous descent
Grade distance: 450 m (1480 ft)
To determine travel performance: Read from
gross weight down to the percent of total
resistance. From this weight-resistance point,
read horizontally to the curve with the high-
est obtainable speed range, then down to
maximum speed. Usable rimpull depends
upon traction available and weight on drive
wheels.
To determine brake performance: These
curves are provided to establish the maxi-
mum speed and gearshift position for
safer descents on roads with a given dis-
tance. Read from gross weight down to
the percent of total resistance. From this
weight-resistance point, read horizontally
to the curve with the highest obtainable
speed range, then down to maximum
descent speed the brakes can safely han-
dle without exceeding cooling capacity.
