METHOD FOR LOADING
WARNING
Do not load while dump body is RAISED.
NOTICE
• When traveling, always set the dump lever to “FLOAT” position, regardless of whether the machine
is loaded or not loaded.
• If the gear shift lever is shifted to a position other than NEUTRAL position (N) when the dump lever
is not at “FLOAT” position, the centralized warning lamp will light up and the alarm buzzer will
sound.
• Apply the parking brake during the loading operations.
If large rocks are loaded directly onto the dump body by using a large-sized loader, etc., the dump body may be
deformed locally.
1.
When loading the large rocks, load the soil and sand first as cushion material.
2.
After loading the soil and sand, load the rock onto them.
The impacts to the dump body are reduced by this method.
In addition, when loading the rocks that exceed the following conditions, install the optional body reinforcement
plate.
• Rocks with one side 0.5 m or more
• Rocks of hardness more than 4.5 (Mohs scale)
• A rock with weight of 300 kg or more
• When transporting the steel ingots
HANDLING PAYLOAD METER
OUTLINE OF SYSTEM
The payload meter detects the signals from the suspension pressure sensors, clinometer during travel and cal-
culates the payload by processing the data statistically.
The obtained payload is displayed on the machine monitor and with the external display lamps.
You can download the data saved in the payload meter to a personal computer by using the special software (if
equipped).
Maintain the road surface, smoothly accelerate, and smoothly apply the brake. Otherwise, the roughness of the
road surface, sudden acceleration, and abrupt braking deteriorate the accuracy of the calculation.
Although the following functions are installed, you do not need to change them for the standard operation. If set-
ting is required, ask your Komatsu distributor.
Setting of Loading End Travel Dist
The payload meter judges that loading is completed when the machine travels continuously 160 m from the
loading pit. Since the payload meter cannot recognize a dumping performed before 160 m traveling as a dump-
ing, the cycle data may not be recorded correctly. Setting of loading end travel distance is used to change the
setting when the distance between the loading pit and dumping pit is very short.
