RT9130E-2 OPERATOR MANUAL OPERATING CONTROLS AND PROCEDURES
Traveling — Towing/Pulling
To avoid severe damage to the drive train while using the
crane to tow or pull another vehicle, follow these
recommendations:
• Ensure the boom is in a horizontal position and not
elevated above 0°.
• Ensure the outrigger beams and jacks are fully retracted
with the floats properly stowed.
• Tow or pull on open ground when possible.
• Connect to the optional pintle hook (if equipped) or
attach cables/straps to the crane at a point no higher
than the pintle hook height.
• Use four-wheel drive when greater traction is necessary.
(Refer to Four-Wheel Drive Operation, page 3-40 for
operating instructions.)
• Should the crane become mired down, use a tow truck
or tractor to free the vehicle. Severe damage to the
drivetrain may occur if the operator attempts to free the
crane unassisted.
• Conduct all travel with the assistance of a ground person
to warn the operator of any changing conditions in the
terrain being traversed.
Traveling — Being Towed/Pulled
Manitowoc recommends connecting to a pintle hook (if
equipped) or evenly attaching to the tie-down lugs when
being towed by another vehicle.,
• Ensure the boom is in a horizontal position and not
elevated above 0°.
• Ensure the outrigger beams and jacks are fully retracted
with the floats properly stowed.
To avoid severe damage to the drive train while the crane
engine is disabled:
• Disconnect drivelines.
• Disengage parking brake by manually turning parking
brake adjustment until axle turns free.
• Secure steering to prevent turning while towing.
• Conduct all travel with the assistance of a ground person
to warn the operator of any changing conditions in the
terrain being traversed.
CAUTION
Machine Damage Hazard!
Manitowoc recommends towing or pulling another vehicle
with the optional pintle hook (if equipped) or by attaching
at a point no higher than the pintle hook height, or severe
damage may occur to the drivetrain.
Do not tow or pull by attaching to the tie-down lugs unless
the attaching point is no higher than the pintle hook
height.
Use four-wheel drive when greater traction is necessary
to avoid severe damage to the drivetrain.
Should the crane become mired down, use a tow truck or
tractor to free the vehicle. Severe damage to the
drivetrain may occur if the operator attempts to free the
crane unassisted.
CAUTION

away freely without the ability of the operator to stop the
crane.
Ensure wheel chocks are properly placed when parking
crane with the parking brake disabled.
Death or serious injury and damage to machinery could
result from moving machinery.
