second (II) gear position to continue to increase speed.
For additional speed, continue shifting to a higher gear.
Traveling — Reverse
NOTE: Cab must be in the fully lowered position for the
drive functions to operate. If cab is not in the fully
lowered position, the Cab Not Fully Lowered
Indicator is on.
NOTE: The standard driving configuration for the
GRT9165 is with the boom centered over the single
front axle. The crane can also be driven with the
boom centered over the dual rear axles. Before
driving with the boom over the rear of the crane,
operator must press the Steering Reversal Switch
to reverse the driving controls, including the
transmission shift lever control. Thus, the direction
the boom is pointing, and the operator is facing, is
always considered forward.
Traveling in reverse is similar to traveling forward, except for
shifting Transmission Shift Lever to reverse (R). Refer to
Traveling — Forward, page 4-17
Steering
Steering is accomplished by the Steering Wheel
(1, Figure 3-2) and the Rear Steer Switch (19, Figure 3-17).
These two controls, used individually or together, provide
front wheel steering (single axle), rear wheel steering
(tandem axles), six-wheel steering, and crab steering
(Figure 4-3).
The Rear Steer Switch can only be operated when one of the
following conditions exists:
• Transmission is in Neutral
• Transmission is in four-wheel drive (low range) and
crane speed is less than 8 kph (5 mph)
• Transmission is in two-wheel drive (high range) and first
gear is selected
If operator attempts to use the rear steer switch while
transmission is in second or third gear, and two-wheel drive
is selected, the following alerts come on:
• Gear Indicator (1, Figure 4-77) on ODM Main Screen
flashes between “F1” and the current gear selected (or
“R1” and the current gear selected if in reverse)
• Buzzer comes on and goes off in sequence with the
flashing Gear Indicator
Front Wheel Steering
Conventional front wheel (single axle) steering is
accomplished with the Steering Wheel. This method of
steering should always be used when traveling at higher
speeds.
CAUTION
Possible Machine Damage!
Do not down-shift to a lower gear if road speed is greater
than maximum speed of the lower gear.
CAUTION
Machine Damage Hazard!
Engage turntable lock pin for travel. Failure to engage
lock pin may allow superstructure to swing uncontrolled,
damaging machine and/or property.
CAUTION
Possible Machine Damage!
Apply service brakes and bring crane to a complete stop
before shifting transmission into reverse.
