To use the table, find the material name and see what its maximum density is.
Then, multiply the loader rating of the attachment by the material density to
determine if the attachment can safely be used. See page 71 for a listing of
attachments and their loader ratings.
Note: Where the material density is listed as a range (clay at 80-100 lb/ft
3
, for
example), always use the maximum density (100 lb/ft
3
in this example) for
making calculations. Also, see the following examples.
Example 1: If clay (density of 80-100 lb/ft
3
) is to be hauled using a 3935
model loader using Dirt/Construction Bucket #808248, the bucket capacity is
9.5 ft
3
and the loader rating is 1250 lb. Multiply the density of clay (100 lb/ft
3
)
by the capacity of the bucket (9.5 ft
3
) to achieve the weight being carried.
(100 lb/ft
3
x9.5ft
3
= 950 lb) This number is less than the machine rating so
you could safely use this bucket in this application.
Example 2: If potash (density of 68 lb/ft
3
) is to be hauled using a 3635 model
loader using Utility Bucket #808249, the bucket capacity is 13.5 ft
3
and the
loader rating is 850 lbs. Multiply the density of potash (68 lb/ft
3
)bythe
capacity of the bucket (13.5 ft
3
) to achieve the weight being carried (68 lb/ft
3
x
13.5 ft
3
= 918 lb). This number exceeds the machine rating and a
counterweight will be required. With the counterweight installed, the loader
rating increases to 950 lb (850 lb loader rating + 100 lb counterweight). The
bucket can now be used safely in this application.
