TRUCK CAB CONTROLS
The truck cab controls described here are those controls that
are used in conjunction with the crane controls.
Truck Cab Ignition Switch
Truck cab ignition switch must be OFF in order for crane cab
ignition switch to be operable.
Power Take Off (PTO)
Manual Shift Control
The PTO is engaged when the knob on the dash or floor is
pulled out and disengaged when the knob is pushed in. The
truck gear shift lever must be in neutral and the clutch
depressed whenever the knob is moved.
Air Shift Control
The PTO is engaged when the switch is moved to apply air to
PTO and disengaged when switch is in off position. The truck
gear shift lever must be in neutral and clutch depressed
when switch is moved. The transmission selector lever must
be returned to “N” for stationary vehicle operation. The
power take-off may be disengaged while in any transmission
range provided that the load has first been removed from the
PTO.
Electric Shift Control
Full torque electric shift PTO's are controlled by a switch. To
operate, disengage the clutch, shift to fourth or fifth gear, and
the move the switch down to engage the PTO or up to
disengage the PTO. Return the gear shift to neutral and
engage the clutch.
Power Shift Control
If the vehicle is equipped with an automatic transmission, the
power take-off must be engaged with the engine at idle. See
transmission manufacturer’s instructions for special
procedures.
Park Brake
The truck brake must be firmly set before leaving cab to
begin operation. If the ground surface is icy or slick or is
sloped, you may be required to help immobilize the truck with
wheel chocks.
Engine Speed Governor
Some diesel engines are equipped with a variable speed
governor which overrides the engine speed governor. If
equipped, two knobs in the cab select between crane
operation and normal driving operation.
Neutral Start/Safety Switch
The truck must be equipped with a neutral/start safety switch
on transmission. Check occasionally to ensure it is working
correctly and repair if it is not.
CRANE CAB CONTROLS
The following sections describe controls located in the crane
cab.
Crane Cab Operator Seat
The crane cab operator seat (Figure 3-5) is equipped with a
weight-sensitive sensor that detects of the seat is occupied.
The operator must be sitting in the operator seat to use crane
functions. Crane functions are disabled if the operator seat is
unoccupied. The outriggers and counterweights can be
operated from their respective control panels if the operator
seat is unoccupied.
Crane Cab Left Armrest
The crane cab armrest (Figure 3-5) is equipped with a
proximity switch that detects the armrest’s position. The
armrest must be in the DOWN position to operator crane
functions. When the armrest is UP, crane operations are
disabled, even if an operator is in the crane cab operator
seat. The outriggers and counterweights can be operated
when an armrest is in the UP position.
Outrigger Controls
The outriggers can be operated from three locations,
including the keypad controller located on the (Figure 3-1)
crane cab console and two ground station control keypads
(Figure 3-2) located on the left and right sides of the carrier
frame. The cab outrigger controller contains the controls for
extending and retracting the outrigger beams, for raising and
lowering the outrigger stabilizer (jack) cylinders and for
raising and lowering the single front outrigger (SFO), if
equipped. The right (passenger) side ground station controls
all vertical outrigger cylinders and the SFO (if equipped), but
only the horizontal beams on the right (passenger) side of
the crane. The left (driver) side ground station controls all
vertical outrigger cylinders and the SFO (if equipped), but
only the horizontal beams on the left (driver) side of the
crane.
The outrigger midspan selector pin (1, Figure 3-1) can be
used to extend the outrigger to 50% of its length. On the
NTC60L only, the outrigger 75% selector pin (11) can be
used to extend the outrigger to 75% of its length. For more
information about deploying the outriggers, see “Outrigger
Setup” on page 4-1.
