how to measure the capacity that can be carried by an excavator bucket?
Buckets come as sizes, like a two yard bucket, etc. That's the capacity in volume. To convert that to weight, you need an average weight of your product by volume, like 25 pounds per cubic foot. Then it's just math: Two cubic yards at 27 cubic feet per cubic yard times 25 pounds per cubic foot is 1,350 pounds per bucket full.
