Loader and Dump Truck Combination Method
d
WARNING:
Always maintain a flat work site surface. Avoid rapid
turns 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 to avoid personal accidents.
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
available trucks, select the most efficient method.
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
turn its direction so that the wheel loader faces the
parked dump truck at a right angle. 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. If 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 lightly hit the bucket to
the stoppers.
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, lightly tap the bucket on the ground
to stabilize 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. 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 truck
body.
Loading times become shorter using this loading method,
reducing the total working cycle time and increasing 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.
