Maximum Material Density at
Capacity
The density of the materials moved by the bucket
varies and, therefore, so does the amount of material
that the bucket can carry before reaching the
maximum load rating. The first 2 tables lists the
density of material that can be carried, both heaped
and struck (i.e., leveled off), in the bucket. The
Material Density table lists common materials and
their densities.
