PRECAUTIONS FOR TOWING MACHINE
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.
• Always wear leather gloves when handling the wire
rope.
• 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 disabled machine
cannot be operated, do not let anyone ride on the disa-
bled machine.
NOTICE
• The maximum towing capacity for this machine is 247569 N{25245 kg}. Do not tow any load greater
than this.
• Towing is only permitted in order to move a disabled machine to a place where it is possible to per-
form inspection and maintenance.
Do not tow it a long distance.
• Consult your Komatsu distributor for information about towing a disabled machine.
This machine must not be towed except in emergencies. However, if it is avoidable to tow the machine, take the
following precautions.
• When towing a machine, tow it at a low speed of less than 2 km/h, and for a distance of a few meters to a
place where repairs can be performed. This method is applied only in emergencies. If the machine must be
moved long distances, use a transporter.
• Use a towing machine of the same class as the machine being towed.
Check that the towing machine has ample braking power, weight, and rim pull to allow it to control both ma-
chines on slopes or on the tow road.
• When towing, set the articulation lock of the towed machine to LOCK position.
However, when towing in places where it is needed to steer, set the articulation lock to FREE position. Use
2 towing machines of the same class or larger than the machine being towed: connect one machine each to
the front and rear of the machine being towed.
• 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 protective plates on both the towing
machine and the machine being towed.
