Travel Operation
1. Before traveling:
a. Plan travel route. It must be free of ground and
overhead constructions.
b. Check crawlers for proper adjustment.
c. Warn personnel to stand clear of travel area. Do not
travel without a signal person.
2. Turn off travel park switch.
3. Turn on drum 3 park switch when operating travel.
4. Position boom at or above boom angle given on capacity
chart when traveling with load.
5. Travel with boom in-line with crawlers except when
swinging is necessary while traveling. Travel with boom
facing direction of travel.
6. For traveling with load, carry load as close to ground
as possible; stabilize load with taglines.
For traveling without load, carry load block and weight
ball low enough that they cannot swing into boom or jib.
If desired, tie off load block at front of rotating bed.
7. Increase engine speed to desired rpm with hand throttle.
Depress foot throttle to momentarily increase engine
speed when more power is required.
8. Select desired travel speed, low or high.
NOTE: The following directions of travel are with front of
rotating bed and front of carbody facing same
direction.
• Operator’s cab is at front of rotating bed
• Carbody/crawler control valve is at front of
carbody
If front of the rotating bed and front of carbody
face in opposite directions, crane will travel in
the direction opposite of handle movement.
WARNING
Tipping Hazard!
Travel surface must be firm and uniformly supporting.
For traveling with load, grade must not exceed 1% in
any direction.
For traveling without load, grade in direction of travel
must not exceed 30%; grade from side to side must not
exceed 2%, measured at boom hinge pins. For all travel
on grades, see Maximum Allowable Travel Specifications
Chart in Capacity Chart Manual.
Failing to comply with above specifications can result in
tipping.
Moving Crane Hazard!
Know position of rotating bed with relation to front of
carbody before traveling. An accident can result if crane
travels opposite of intended direction.
Flying Object Hazard!
Excessive dirt build-up at tumbler and front roller ends of
crawlers can result in excessive tension in tread
connectors. Tread connectors can break if over
tensioned, causing treads to fly apart unexpectedly with
dangerous force.
CAUTION
Crawler Damage!
Avoid damage to crawler components (treads, rollers,
frames)!
Use care to prevent dirt from piling up at tumbler and front
roller ends of crawlers when turning on soft surfaces:
• Bring crawlers to a complete stop before changing
travel direction
• Turn a few degrees. Then slowly travel forward or
reverse so dirt falls away from crawlers. Continue this
procedure until desired turn has been made
• Avoid sharp turns (Figure 3-27
) if possible
• Make gradual turns (Figure 3-28
) or counter-rotate
(Figure 3-29
) whenever possible so both crawlers are
always powered
• Clean crawlers often
• Keep crawler treads properly adjusted
CAUTION
Boom Damage!
Avoid shock loading boom and rigging!
• Perform all travel functions — starting, turning,
stopping — slowly and smoothly
