RECOMMENDED APPLICATIONS
In addition to the following, it is possible to further increase the range of applications by using various attach-
ments.
DIGGING WORK
BACKHOE WORK
The backhoe is suitable for digging in areas that are at a lower level than the machine.
When the condition of the machine is as shown in the figure
(angle between "bucket cylinder and link" and "boom 2 cylinder
and boom 2" is 90 deg.), the maximum excavation force is ob-
tained from the pushing force of each cylinder.
During excavations use this angle to optimize the operation
and make the work more efficient.
The excavation area with its boom is equal to an angle of 45
degrees away from the machine and 30 degrees 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.
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 re-
verse direction.
