What is the maximum capacity of a bucket when the material is heaped above the edges?

The maximum capacity of a bucket when the material is heaped above the edges refers to the heaped capacity, which accurately describes the maximum volume of material that can be carried when it exceeds the bucket's rim.

When evaluating different types of bucket capacities, "heaped" capacity is distinguished from other measurements such as "struck" capacity, which refers to the volume of material that can be carried when it is leveled out without exceeding the rim. Other terms like "struck capacity" and "level" do not account for the extra volume added when material is heaped or mounded above the edge of the bucket.

Understanding the heaped capacity is crucial in construction and excavation work as it allows operators to maximize the efficiency of their equipment and ensure that they are transporting the most material in a single load, which can significantly impact productivity and project timelines.
