INTRODUCTION
intelligent Machine Control
The system that utilizes ICT (Information Communication Technology) in each stage of earth moving operation,
such as survey, design, operation, supervision, examination and maintenance.
It enables the highly efficient and highly accurate earth moving operation by utilizing information provided in
each stage of operation.
Utilizing the information provided in the operation to the other operations enables better productivity and quality
in the whole operation.
MACHINE FEATURES
For this machine, current position information is obtained by using GNSS satellite and the base station. By using
the obtained current position information and information data for the operation, blade is automatically control-
led.
Under the blade automatic control, even if the operator does not operate the blade control lever, the blade auto-
matically moves along the preset design surface. By using this function effectively, you can easily build a ground
surface as designed.
When the load to blade increases, the blade is automatically raised to keep the constant targeted load by ad-
justing lifting amount, before the machine becomes impossible to travel forward. Therefore, this function can be
used not only for the finishing leveling but also the dozing and carrying operation.
Use this machine mainly for the following operation.
• Dozing work
• Leveling work
For detail of work procedure, see “PRECAUTIONS WHEN USING BLADE AUTOMATIC CONTROL”.
This machine has the current ground display (as-built) function which grasps the ground shape under the track
as well as the operation and display it on the control box screen. By using this function, the progress of opera-
tion can be checked in real time on the control box screen.
In order to use the blade automatic control or current ground display (as-built) function, following device is need-
ed besides this machine.
• GNSS satellite (GPS, GLONASS)
Use it at a place under the open sky where has no obstacle.
• Base station
For the usable the base station, consult your Komatsu distributor in advance.
• Operation information data
Project file is necessary, which contains the data necessary for “intelligent Machine Control” such as the
design surface, base point, etc.
For details, consult your Komatsu distributor beforehand.
Observation items for use
• While the blade automatic control is in operation, the blade moves even if the operator does not operate the
blade control lever.
Before turning on the blade automatic control, check thoroughly if there are any persons or obstacles in the
area around the machine.
• While the blade automatic control is in operation, if the operator operates blade control lever, this blade lev-
er operation is given the priority and the blade moves as operated by the operator. When the operator stops
lever operation, the blade automatic control restarts.
While the blade automatic control is in operation, do not release your hand from the blade control lever, so
that you can avoid the danger immediately if any.
• When performing the inspection, maintenance, moving and loading/unloading on the trailer etc., i.e. other
operation than the operation by “intelligent Machine Control” at the jobsite, turn off the blade automatic con-
trol and turn off the control box power supply.
• You can turn off the blade automatic control by setting the work equipment lock lever to LOCK position.
