The parking brakes are controlled by a push-pull knob
on the front console. Pull the knob out to apply and push
the knob in to release the parking brake.
Engine Braking
NOTE:
Do not keep a foot lightly on the clutch pedal or the
throttle pedal. This will cause the engine brake not
to come on.
Compression brakes are quieter on engines with
the exhaust aftertreatment feature.
By energizing the engine brake, the power producing diesel
engine, in effect, becomes a power absorbing air
compressor. To retard a crane on a downgrade using the
Engine Brake, the operator selects a gear which will provide
a balance between engine speed and road speed, then
engages the engine brake. If the engine speed exceeds
maximum rated RPM for a desired speed, a lower gear can
be selected or intermittent use of the service brakes can be
made. This selection of a lower gear will generally allow
complete control of the crane by the engine brake leaving the
service brakes in reserve to be used for emergency stops.
With the engine brake turned on, the engine brake will not be
energized until the momentum is driving the engine.
1.
Position the engine brake On/Off switch to ON (push top
of switch).
2.
Position the engine brake switch to either HIGH (press
top of switch) or LOW (press bottom of switch) position,
depending on the amount of braking desired.
3.
Let off the throttle to activate the engine braking system
and slow the crane.
NOTE:
The engine braking system will automatically
deactivate when the throttle is depressed.
TRAILING BOOM (OPTIONAL)
The trailing boom option allows the crane to be driven on
roads or surfaces that normally cannot support the axle
loads by allowing a portion of the boom weight to be carried
on the boom trailer.
In order to use the trailer the boom lift circuit and swing brake
circuit must be opened to allow the boom to freely move.
After transporting and before using the crane the lift circuit
and swing circuit valves (Figure 3-32) must be fully closed by
turning clockwise.
Travel Configuration
1.
Swing the boom to over the rear of the crane.
2.
Align the trailer to the boom supports on the bottom of
the boom (Figure 3-29).
3.
Lower the boom onto the trailer supports.
4.
Align the support pins with the boom attachment lugs.
5.
Connect the control connector (blue) (1, Figure 3-30) to
the rear of the crane.
6.
Connect the brake supply (red) connector (2) to the rear
of the crane.
7.
Connect the electrical cable (3) to the crane.
CAUTION
Before engaging engine brake on slippery roads, be sure
crane is maintaining traction.
