METHOD OF TOWING MACHINE 3
WARNING
Serious injury or death could result if a disabled machine
is towed incorrectly or if there is a mistake in the selection
or inspection of the wire rope.
If the engine does not start, put blocks under the track to
prevent the machine from moving, then release the brake.
If blocks are not use, there is danger that the machine may
move suddenly.
Always check that the wire rope used for towing has ample
strength for the weight of the machine being towed.
Never use a wire rope which has cut strands (A), reduced
diameter (B), or kinks (C). There is danger that the rope
may break during the towing operation.
Always wear leather gloves when handling wire rope.
Never tow a machine on a slope.
During the towing operation, never stand between the tow-
ing machine and the machine being towed.
Operate the machine slowly and be careful not to apply
any sudden load to the wire rope.
NOTICE
The maximum towing capacity for this machine is 197,100
N (20,100 kgf).
Always carry out towing operations within the maximum
towing capacity.
For details of the method of towing, please contact your Komatsu distributor.
q If the engine stops or the oil pressure in the brake circuit lowers because of a trouble in the hydraulic system,
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. Ask your Komatsu distributor.
q Moving a machine by towing is only used to move it to a place where it is possible to carry out inspection and
maintenance. It is not intended for moving the machine long distances. Do not use this method for towing the
machine for long distances.
q If it is impossible to operate the steering and brakes of the machine being towed, do not let anyone ride on the
machine.
q 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 line.
