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.
Loading Work 3
In places where the swing angle is small, set the dump truck in
a place where it is easy for the operator to see. This makes
operations more efficient.
When loading, it is easier to carry out the loading operation
from the rear of the dump truck body, and more of the soil can
be loaded to the sides.
