RECOMMENDED APPLICATIONS 3
In addition to the following, it is possible to further increase the range of applications by using various attachments.
Backhoe Work 3
A backhoe is suitable for excavating areas that are lower than
the machine.
When the condition of the machine is as shown in the diagram
on the right (angle between [bucket cylinder and link] and [arm
cylinder and arm] is 90°), the maximum excavation force is
obtained from the pushing force of each cylinder.
When excavating, use this angle effectively to optimize your
working efficiency.
The range for excavating with the arm is from a 45° angle away
from the machine to a 30° angle towards the machine.
There may be some differences depending on the excavation
depth, but try to stay within the above range rather than operat-
ing the cylinder to the end of its stroke.
Ditching Work 3
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.
Loading Work 3
In places where the swing angle is narrow, work efficiency can
be enhanced by locating the dump truck in a place easily visi-
ble to the operator.
Loading is easier and capacity greater if you begin from the
front of the dump truck body than if loading is done from the
side.
