WORK POSSIBLE USING COMPACT HYDRAULIC EXCAVATOR
In addition to the following, it is possible to further increase the range of applications by using various attachments.
Backhoe Work
This is suitable for excavating places lower than the machine.
When work equipment is in condition shown in diagram on right
Bucket cylinder and link
When the center line of arm cylinder and arm foot pin is at 90°, the
push-out digging force of each cylinder is the maximum.
Make the optimum use of this angle during digging operations to
increase the operating 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,
try to keep within the above range rather than operating to the end
of the cylinder stroke.
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.
Loading Work
In places where the swing angle is small, work efficiency can be
enhanced by locating the dump truck in a place easily visible to the
operator.
Loading dump trucks is easier and the loading capacity is greater
if the hydraulic excavator loads from the rear of the dump truck
rather than from the side.
