# How To Calculate Loader Bucket Capacity

How to calculate loader bucket capacity? This is a problem that many customers are confused about. In addition to simply multiplying the cross section of the bucket by its width, there are many more to calculate the capacity of the loading bucket. The simple method is to use two different angles of repose defined by the Society of Automotive Engineers to allow relative grading of the bucket. If you don't know the actual angle of repose, use 2: 1 for wheel loader buckets and 1: 1 for hydraulic excavator buckets, or you can make an estimate.

The specific estimation process of the loader bucket capacity without knowing the angle of repose is as follows:

1 Draw the outline of the cross section of the bucket on a large piece of cardboard.

2 Draw a straight baseline to connect the open end of the cross section. Draw a vertical line at the midpoint of the baseline to construct the heap area. For a 2: 1 stack, make the vertical line a quarter of the baseline length. For a 1: 1 heap, make it half the baseline length.

3 Draw a straight line connecting the two ends of the baseline to the ends of the vertical line to indicate how much extra area the cross section of the stack has.

4 Draw a grid on the cross-sectional representation. For ease of estimation, set the grid square to 1 foot square for larger buckets; if higher accuracy is required in smaller buckets, set the grid's margin to 6 inches so that each The square represents a quarter square foot.

5 Calculate the number of squares occupied by the cross section to estimate the cross-sectional area of the stack. Merge partial squares and treat them as one square. Multiply the area found by the width of the bucket to get the total capacity.
