OPERATING CONTROLS AND PROCEDURES
ensure the safety of all personnel performing the operation
and/or working around the crane.
Should the operator need to traverse slopes outside the
criteria defined in the above guidelines contact The
Manitowoc Company, Inc. for further guidance.
Traveling with Elevated Boom
Overhead Objects Hazard
Contacting overhead objects while driving the crane may
result in death, severe injury, and/or equipment damage.
Traveling with the boom elevated should only be
attempted under the controlled conditions specified in this
section.
Exercise caution whenever driving the crane with the boom
elevated. Travel with the boom elevated is permitted as long
as the following steps are followed.
• Limit travel to firm, level surfaces.
• Inspect the route of travel prior to moving the crane. Pay
particular attention to any changing conditions in the
terrain being traversed. Also, avoid any overhead
obstructions.
• Travel must be performed in a controlled fashion.
• Do not exceed a speed of 15 mph.
• Inflate tires to the recommended pressure for travel
operations.
• When using the towing attachments, the boom must
remain horizontal.
• Fully retract all boom sections.
• Refer to Traveling with Boom Extension Erected, page
3-24 if the boom extension is in the erected position.
• Position the boom over the front of the crane.
• Engage the swing brake and turntable lock pin.
• The hook block may be reeved over the main boom
nose. The headache ball may be reeved over the main
boom nose or auxiliary boom nose. The block and ball
may be suspended below the boom nose. It is also
acceptable to secure the block or the ball to the tie down
point on the carrier to prevent swinging if necessary.
• Limit boom angle to a maximum of 20°.
• Do not support any load from the boom (see Pick and
Carry Load chart for limitations for this application).

RT600E OPERATOR MANUAL
• Remove all cribbing or other non-standard accessories
from the crane.
• Avoid holes, rocks, extremely soft surfaces and any
other obstacles that might subject the crane to undue
stresses and possible overturn.
• Ensure adequate
obstructions that the crane may be required to travel
beneath.
• Ensure that all personnel involved in the operation and
those working around the crane are aware of any
hazards that may be encountered and are trained about
how to avoid the hazards.
Traveling with Boom Extension Erected
Follow the steps below when traveling with the extension
erected.
• Position boom extension at minimum offset and pin
stinger section in the fully retracted position.
• Travel only on a firm, level surface.
• Fully retract the main boom.
• Limit main boom angle to a minimum of 0° and a
maximum of 20°.
• Do not exceed a speed of 2.5 mph (4 km/h).
• Position the boom over the front of the crane.
• Engage the swing brake and turntable lock pin.
• Hookblock may be reeved over main boom nose,
hanging 3 ft (0.9 m) below sheave.
• Headache ball may be reeved over boom extension,
hanging 3 ft (0.9 m) below sheave.
Extended Travel
Depending upon the tire manufacturer, the higher inflation
pressures normally specified for lifting on rubber are not
recommended for site to site transfer over extended
distances. The higher static/creep 5 mph (8 km/h) inflation
pressures may remain in the tire while operating the crane
on site within a distance of less than 4 mi (6.4 km).
CAUTION
Tire Damage!
For extended travel, check the cold tire pressure prior to
start. (Refer to tire inflation chart in Load Chart Book.)
After every one hour of travel time, regardless of ambient
temperature, stop and allow the tires to cool off for at least
30 minutes. At the destination, the tires must be allowed
to cool to ambient temperature before crane lifting on
rubber.
