Travel Operation
7. Before traveling:
• Check the Maximum Allowable Travel Specifica-
tions chart located in the Capacity Chart Manual.
• Plan the travel route. It must be free of obstructions.
• Check the crawlers for proper adjustment.
• Warn personnel to stand clear of the travel area. Do
not travel without a signal person.
8. Turn off the travel park switch.
9. When traveling with a load, position the boom at or
above the boom angle given in the capacity chart.
• When traveling with a load, carry the load as close
to the ground as possible. Stabilize the load with
taglines.
• When traveling without a load, carry the load
block and the weight ball low enough so that they
cannot swing into the boom or jib. If desired, tie off
the load block at the front of the rotating bed.
10. Align the boom with the crawlers except when swinging
is necessary while traveling. Travel with the boom facing
in the direction of travel.
11. Increase the engine speed to the desired rpm with the
hand throttle. When more power is required, press the
foot throttle to momentarily increase the engine speed.
12. Select the desired travel speed—low or high.
NOTE Travel speed may be changed while traveling. The
travel motors will shift immediately from high to low
when low speed is selected.
In low speed, the travel motors operate at
approximately 1/3 of high speed.
The 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 the
motors to shift from low to high speed.
CAUTION
Avoid Accelerated Crawler Wear
To reduce wear and tear of the crawler components
(treads, rollers, frames), try not to allow dirt to pile up at
the tumbler and front roller ends of the crawlers.
Dirt can pile up when turning on soft surfaces. To avoid
this:
• Bring the crawlers to a complete stop before
changing direction of travel.
• Turn a few degrees. Then slowly travel forward or
reverse so the dirt falls away from the crawlers.
Continue this procedure until the desired turn has
been made.
• Avoid sharp turns if possible.
• Make gradual turns or counter-rotate whenever
possible so both crawlers are always powered.
• Clean the crawlers often.
• Keep the crawler treads properly adjusted.
Avoid Boom Damage
• Abrupt travel operation could result in shock loading
the boom and rigging. To avoid this, perform all travel
functions—starting, turning, stopping—slowly and
smoothly.
WARNING
Crane Tipping Hazard
For all travel, refer to the Maximum Allowable Travel
Specifications chart located in the Capacity Chart Manual.
The travel surface must be firm and uniformly supporting.
When traveling with load:
• The grade must not exceed 1% (0.5°) in any direction.
For traveling without load:
• The allowable grade in the direction of travel depends
upon boom angle (refer to the Maximum Allowable
Travel Specifications chart).
• The grade from side-to-side must not exceed 2%
(1.0°), measured at the boom hinge pins.
Failure to comply with the above instructions can result in
tipping.
WARNING
Moving Crane Hazard
Know the position of the rotating bed with relation to the
front of the carbody before traveling. An accident can
result if the crane travels opposite of the intended
direction.
Flying Object and Tread Damage Hazard
Excessive dirt build-up at the tumbler and front roller ends
of the crawlers can result in excessive tension in the tread
connectors. The tread connectors can break if over-
tensioned, causing the treads to fly apart unexpectedly
with dangerous force.
