5-6.6
Front Axle Steering. Since most craning operations are performed with the
front axle to the rear of the superstructure, the FRONT AXLE STEERING Control (55, Figure 5-
desired position actuates the front axle steering cylinders, turning the front wheels to steer the
crane in the desired direction as indicated by the light to the left or the right of the FRONT AXLE
STEERING Control (55) on the superstructure cab console.
WARNING
The Steering Wheel (7, Figure 5-1) in the carrier cab
will turn when performing front axle steering from the
superstructure cab. Use care to avoid injury to
personnel occupying the carrier cab.
WARNING
To avoid personal injury and/or catastrophic
steering gear failure, remove any restraining devices
from the carrier cab steering wheel before operating
from the superstructure cab.
CAUTION
Operate front axle steering only for added job site
maneuverability when traveling at low speeds.
a.
Place FRONT AXLE STEERING Control (55, Figure 5-2) to right to steer
right or to the left to steer left.
b.
Observe front axle direction lights, to the left or right of the FRONT AXLE
STEERING Control (55), for an indication of which direction crane will
turn, except when crabbing.
c.
Return FRONT AXLE STEERING Control (55) to center (off) position.
5-6.7
Four-Wheel Steering. Four-wheel steering is accomplished by using both the
Steering Wheel (15, Figure 5-2) and the FRONT AXLE STEERING Control (55). Depending upon
which direction the operator wishes to travel, the steering wheel is turned in the same direction of
the FRONT AXLE STEERING Control (55) position. This method of steering allows the crane to
turn or maneuver in close, restricted areas.
5-6.8
Wheel (15, Figure 5-2) and the FRONT AXLE STEERING Control (55). Depending upon which
direction the operator wishes to travel (crab), the steering wheel is turned in the opposite direction in
which FRONT AXLE STEERING Control (55) is positioned. This method permits driving the crane
forward or in reverse at an angle from straight ahead in the crabbing manner.
