14000 OPERATOR MANUAL OPERATING CONTROLS AND PROCEDURES
H – Travel Controls
See Figure 3-15 for the travel controls.
Crawlers have spring-applied, hydraulically-released disc
brakes.
• Both crawler brakes release when either crawler handle
is moved in either direction from off
• Both crawler brakes apply when both crawler handles
are moved to off
• Both crawler brakes apply to hold crane in position if
power is lost for any reason
H1. Travel Park Switch
Press TOP of rocker to TURN ON travel park switch. With
travel park switch on, travel handles are inoperable and
brakes are applied.
Press BOTTOM of rocker to TURN OFF travel park switch.
With travel park switch off, travel handles are operable and
brakes are applied and released in conjunction with handle
movement.
H2. Travel Speed Selector
Press TOP of rocker to operate travel motors in HIGH speed.
High speed operation provides maximum available travel
speed for traveling long distances.
Press BOTTOM end of rocker to operate travel motors in
LOW speed. Low speed operation provides smooth starts
and stops and more precise control of travel motors than
high speed.
In low speed, travel motors operate at approximately 1/3 the
speed of high speed.
NOTE: It is all right to change travel speed while traveling:
Travel motors will shift immediately from high to low
when low speed is selected.
Travel motors will not shift from low to high when
high speed is selected until:
• Engine speed is at high idle
• Hydraulic pressure is low enough to allow
motors to shift from low to high speed
H3. Travel Cruise Selector
Travel cruise selector allows crawlers to be operated in
either direction at a selected speed without the operator’s
hand on crawler handles.
Move both crawler handles in either direction from off to
select desired speed and direction of travel. Press TOP of
rocker to TURN ON travel cruise. Release handles to off.
Crawlers continue to travel at selected speed and direction.
