Bucket Selection
To use the table, find the material to be loaded and read its maximum density.
Then multiply the volumetric rating of the attachment by the material density to
determine if the attachment can safely be used. See page for a listing of attach-
ments and their load ratings.
Note: Where the material density is listed as a range (clay at 80-100 lbs/ft
3
, for
example), always use the maximum density (100 lbs/ft
3
in this example) for
making calculations. Also, see the following examples.
Example 1: If clay (density of 80-100 lbs/ft
3
) is to be hauled using a
SL4840 model loader using a 10.8 ft
3
Dirt/Construction bucket, the bucket
capacity is 10.8 ft
3
and the loader rating is 1700 lbs. Multiply the density of clay
(100 lbs/ft
3
) by the capacity of the bucket (10.8 ft
3
) to achieve the weight to be
carried (100 lbs/ft
3
x 10.8 ft
3
= 1080 lbs). This number is less than the machine
rating, allowing safe use of this bucket in this application.
Example 2: If granite (density of 1488-1776 kg/m
3
) is to be hauled using a
SL5640 model loader using a 0.43 m
3
Dirt/Construction bucket, the bucket
capacity is 0.43 m
3
and the loader rating is 907 kg. Multiply the density of granite
(1776 kg/m
3
) by the capacity of the bucket (0.43 m
3
) to achieve the weight to be
carried (1776 kg/m
3
x 0.43 m
3
= 763.7 kg). This number is less than the machine
rating, allowing safe use of this bucket in this application.
