RECOMMENDED APPLICATIONS
In addition to the following, it is possible to further increase the range of applications by using various attachments.
Backhoe Work
A backhoe is suitable for excavating at a position lower than the
machine.
When the condition of the machine is as shown in the diagram at
right, each cylinder's maximum pushing excavation force is
obtained when the bucket cylinder and link, arm cylinder and arm
are at 90
°
.
When excavating, use this angle effectively to optimize your work
efficiency.
The range for excavating with the arm is from a 45
°
angle away
from the machine to a 30
°
angle toward the machine.
There may be some differences depending on the digging depth,
not try to keep within the above range rather than operating to the
end of the cylinder stroke.
Shovel Work
A shovel is suitable for excavating at a position higher than the
machine. Shovel work is performed by attaching the bucket in the
reverse direction.
Ditching Work
Ditching work can be performed efficiently by attaching a bucket
which matches the digging operation and then setting the tracks
parallel to the line of the ditch to be excavated.
To excavate a wide ditch, first dig both sides and then finally
remove the center portion.
