PRECAUTIONS FOR TRANSPORTATION
When the machine is transported on a trailer, there is danger of serious personal injury or death during transpor-
tation. Always observe the following.
• Always check the machine dimensions carefully. Depending on the work equipment and optional devices
installed, the machine weight, transportation height, and overall length differ.
• Check beforehand that all bridges and other structures on the transportation route are strong enough to
withstand the combined weight of the transporter and the machine being transported.
• This machine needs to be divided into components for transportation depending on the regulation. When
transporting the machine, consult your Komatsu distributor.
PRECAUTIONS WHEN LOADING AND UNLOADING
If handling is wrong when loading or unloading the machine, it is dangerous that the machine may tip over or
fall. It requires particular attention. Always observe the following.
• Perform loading and unloading on a firm, level ground only. Avoid road edge or place near the cliff.
• Always use ramps of adequate strength. Be sure that the
ramps are wide, long, and thick enough to provide a safe
loading slope. Take suitable steps to prevent the ramps
from moving out of position or coming off.
(1) Chocks
(2) Ramp
(3) Center of ramp
(4) Angle of ramp: Max. 15 °.
• Be sure the ramp surface and the platform of trailer are
clean and free of grease, oil, ice, water and other loose
materials. If any, remove them. Remove dirt around the undercarriage of the machine. On a rainy day, in
particular, be extremely careful since the ramp surface is slippery.
• Run the engine at low idle and drive the machine slowly at low speed.
• When on the ramps, do not operate any lever except for the travel lever (travel forward and reverse).
• Never correct your steering on the ramps. If necessary, drive off the ramps onto the ground, correct the di-
rection, then enter the ramps again.
• The center of gravity of the machine will change suddenly at the joint between the ramps and the loading
platform, and there is danger of the machine losing its balance. Drive slowly over this point.
• When loading or unloading to an embankment or platform, make sure that it has suitable width, strength,
and grade.
• For machines equipped with a cab, always lock the door after loading the machine. The door may open
during transportation.
For detail, see “TRANSPORTATION (3-267)”.
• When it is necessary to remove handrails and steps, take care not to lose removed handrails and steps.
Install the removed handrails and steps securely.
