Driving on a slope
Determine the uphill, downhill and side slope
ratings for the machine and determine the slope
grade.
Maximum slope rating, platform
downhill (gradeability):
Z-34/22N: 35% (19°)
Z-34/22 DC: 30% (17°)
Maximum slope rating, platform
uphill:
20% (11°)
Maximum side slope rating:
25% (14°)
Note: Slope rating is subject to ground conditions
with one person in the platform and adequate
traction. Additional platform weight may reduce
slope rating. The term gradeability applies to the
platform downhill configuration only.
Be sure the boom is below horizontal and the
platform is between the non-steer wheels.
To determine the slope grade:
Measure the slope with a digital inclinometer OR
use the following procedure.
You will need:
carpent
er’s level
straight piece of wood, at least 3 feet/1 m long
tape measure
Lay the piece of wood on the slope.
At the downhill end, lay the level on the top edge of
the piece of wood and lift the end until the piece of
wood is level.
While holding the piece of wood level, measure the
vertical distance from the bottom of the piece of
wood to the ground.
Divide the tape measure distance (rise) by the
length of the piece of wood (run) and multiply by
100.
Example:
Piece of wood = 144 inches (3.6 m)
Run = 144 inches (3.6 m)
Rise = 12 inches (0.3 m)
12 in ÷ 144 in = 0.083 x 100 = 8.3% grade
0.3 m ÷ 3.6 m = 0.083 x 100 = 8.3% grade
If the slope exceeds the maximum uphill, downhill
or side slope rating, then the machine must be
winched or transported up or down the slope. See
Transport and Lifting section.
