Loader and Dump Track Combination Method
A loader carries out loading, and carrying and dumping is
carried out by a dump truck. Either V- or I-shape loading
method is employed in this method. Depending on the
work site conditions encountered and matching with avail-
able trucks, select the most efficient method.
WARNING:
• Always maintain a level work site surface. Avoid
rapid swing and/or sudden braking while raising
the lift arm with the bucket loaded to prevent the
machine from tipping over.
• Do not penetrate the bucket into a loading face at
fast travel speeds, possibly resulting in personal
accident.
V-Shape Loading
1. Park a dump truck in a spot located at approx. 60° angle
toward the face of loading by the wheel loader. After
loading material, travel the wheel loader in reverse and
turns its direction so that the wheel loader faces the
parked dump truck at a right angle. Then, travel forward
to carry material onto the dump truck.
2. Position the wheel loader so that the material can be
loaded around the center of the dump body. In case the
dump body is longer than twice the bucket width, load
from the front to rear position of the dump body in order.
3. When dumping sticky material such as clay, move the
bucket lever back and forth to hit the bucket to the stop-
pers. Take a steering angle as small as possible to operate
the machine efficiently.
4. Before raising the lift arm to the maximum height with
the bucket full, vibrate the bucket on the ground to sta-
bilize the material in the bucket to prevent the material
from spilling off the backside of the bucket.
I-Shape Loading
Park a dump truck in a direction parallel to the loading face.
After loading material into the bucket, travel the wheel
loader straight in reverse. Then, move a dump truck to a
spot between the loading face and the wheel loader. Travel
the wheel loader forward to load material onto the dump
body. Loading times become shorter using this loading
method, reducing the total working cycle time and increas-
ing work efficiency. Position the machine down the wind
as much as possible. The engine will not only inhale as little
dust as possible but also operator's eyes will be protected
from being contaminated.
