TOWING THE 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.
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 1,079 kN (110,027 kg).
Always carry out towing operations within the maximum towing capacity.
q
If the machine sinks in mud and cannot get out under its
own power, or if the drawbar pull of the excavator is being
used to tow a heavy object, use a wire rope as shown in
the diagram on the right.
q
Place pieces of wood between wire ropes and body to pre-
vent damage to ropes and body.
q
When towing a machine, travel at a speed of less than 1
km/h for a distance of only a few meters to a place that is
suitable for carrying out repairs.
This is for use only in emergencies.
