PRECAUTIONS FOR TOWING MACHINE
WARNING
Always use the correct towing equipment and towing
method. Any mistake in the selection of the wire rope or
drawbar or the method of towing a disabled machine and
being towed may lead to serious personal injury or death.
• If the engine does not start, block the tracks from
movement, then release the brake. If blocks are not
used, there is a danger that the machine may move
suddenly.
• 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.
• Move the machine slowly.
Do not apply a sudden load to the wire rope.
NOTICE
The maximum towing capacity for this machine is 140000 N {14275 kg}.
Do not tow any load greater than this.
For details of the method of towing, contact your Komatsu distributor.
• If the engine stops or the oil pressure in the brake circuit lowers because of a trouble in the hydraulic sys-
tem, the brake works and the machine cannot move. To move the machine in this case, the oil pressure in
the brake circuit must be heightened to the specified level with a special device. Contact your Komatsu dis-
tributor.
• Moving a machine by towing is only used to move it to a place where it is possible to perform inspection
and maintenance.
Do not tow it a long distance.
• If it is impossible to operate the steering and brakes of the machine being towed, do not let anyone ride on
the machine.
• Keep the angle of the towing line to the minimum. Operate the machine so that the angle does not become
greater than 30 ° from the straight travel direction.
• If the machine gets stuck in the mud or a heavy thing
needs to be towed, install a towing wire rope to the draw
bar pin.
Connect a wire rope to the part indicated with the arrow in
the drawing.
