3.13.3 LOADING MATERIAL ON HEAPS
AND ON LEVEL SURFACES
The efficiency of the bucket depends on how the operator be-
gins to load; keep to the following rules:
1 - Start moving with the arm completely lowered and direct
the bucket toward the base of the heap.
2 - While the material on top of the heap falls into the bucket,
gradually raise the arm and at the same time fold the buc-
ket until reaching the end of stroke.
3 - Invert the machine motion and dump the bucket on to the
truck.
NOTE
q
Start loading the truck from the cab side and, if the material
is sufficiently homogeneous, dump from the maximum
height in order to increase the compactness of the material
and its distribution on the loading surface.
4 - After removing the heap completely, incline the bucket for-
ward, lower the arm until raising the front wheels slightly
and, proceeding in reverse, level the ground distributing
the material uniformly.
Repeat the operation reducing the inclination of the buck-
et for the finishing work.
