3.3.13 OPERATIONS THAT CAN BE PERFORMED WITH THE HYDRAULIC
EXCAVATOR
In addition to those indicated below, many other applications are possible, thanks to the use of various
attachments.
EXCAVATION
When the machine is in the position shown in the diagram on the
right, the maximum digging force and thrusting force of the single
cylinders is obtained when the bucket cylinder and the relevant
articulation, the arm cylinder and the arm are at 90° with respect
to each other.
During digging operations, keep this amplitude to increase the
efficiency of the machine.
The positions available for digging with the arm range from a 45°
angle away from the machine to a 30° angle towards the
machine.
There may be some differences depending on the digging depth,
but it is advisable to try to keep within the above range rather than
operate with the cylinders reaching the end of stroke.
SIDE DITCHING
Ditch digging operations can be performed effectively by installing
a bucket suitable for digging ditches and positioning the tracks
parallel to the line that delimits the edge of the ditch.
o dig wide ditches, excavate the sides first and successively the
central part.
LOADING THE MACHINE
In places where the rotation angle is reduced, the effectiveness of
the operation can be increased by positioning the truck so that the
operator can comfortably see it.
The loading operation is easier and the loading capacity greater if
the hydraulic excavator works from the back and not from the
sides of the truck.
