Table of Common Materials and Densities

Note: The densities listed are average values and intended only as a guide for bucket selection. For a material that is not in the table, obtain its density value before selecting the appropriate bucket.

Bucket Selections

To use the table, find the material to be loaded and 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 page70 for a listing of attachments and their ratings.

Note: Where the material density is listed as a range (snow at 15-50lbs./ft3, for example), always use the maximum density (50 lbs./ft3 in this example) for making calculations. Also, see the following examples.

Example 1: If snow (density of 15-50 lbs./ft3) is to be hauled using an SL1640E model loader using Dirt/Construction Bucket, the bucket capacity is 5.3 ft3 and the Rated Operating Capacity is 850 lbs. Multiply the density of snow (50 lbs./ft3) by the capacity of the bucket (5.3 ft3) to achieve the weight being carried (50 lbs./ft3 x 5.3 ft3 = 265 lbs.). This number is less than the machine rating, so you could safely use this bucket in this application.

Example 2: If charcoal (density of 368 kg/m3) is to be hauled using a SL1640E model loader using a 914mm Dirt/Construction bucket, the bucket capacity is 0.15 m3 and the Rated Operating Capacity is 386 kg. Multiply the density of charcoal (368kg/m3) by the capacity of the bucket (0.15 m3) to achieve the weight to be carried (368 kg/m3 x 0.15 m3 = 55.2 kg). This number is less than the machine rating, allowing safe use of this bucket in this application.
