PRECAUTIONS FOR TOWING MACHINE
k k
WARNING
Injury or death could result if a disabled machine is towed
incorrectly or if there is a mistake in the selection of the
wire rope or drawbar.
• Always confirm that the wire rope or drawbar used for
towing has ample strength for the weight of the ma-
chine being towed.
• Never use the wire rope which has cut strands (A), re-
duced diameter (B), or kinks (C). There is a danger that
the rope may break during the towing operation.
• Wear the leather gloves always when handling the wire
ropes.
• Never tow a machine on a slope.
• During the towing operation, never stand between the
towing machine and the towed machine.
• If the machine moves suddenly, a load is applied sud-
denly to the towing wire or drawbar, and the towing
wire or drawbar may break.
Move the machine gradually to a constant speed.
• Be extremely careful if there is a failure in the engine
or brake system: the brakes will not work.
• If the steering and the brakes on the machine being
towed cannot be operated, do not let anyone ride on
the machine being towed.
NOTICE
• Tow the machine only for a short distance, such as to a place for inspection and maintenance.
Do not tow the machine for a long distance.
• The maximum towing capacity for this machine is as follows. Do not tow any load greater than this.
HD465-8: 356500 N {36340 kg}

• For towing a failed machine, consult your Komatsu distributor.
This machine must not be towed except in emergency. However, if it is unavoidable to tow the machine, pay
attention to the following precautions.
• When towing a machine, tow it at a low speed of 2 km/h or lower, and for a distance of a few meters to a
place where repairs can be performed.
This method is applied only in an emergency. If the machine must be moved a long distance, use a trans-
porter.
• Usually, use a towing machine of the same class as the machine being towed. Check that both towing ma-
chine and towed machine have ample braking power, and rim pull to allow them to control both machines
on slopes or on the tow road.
• Use the specified hook for both the towing machine and the machine being towed.
• To protect the operator if the towing wire or towing bar breaks, install the protective plates on both the tow-
ing machine and the machine being towed.
