Self Dumping Hoppers

Overall structural integrity for our self dumping hoppers are determined by a couple of factors. The first is the steel thickness. The thicker or heavier the steel, the greater the hopper strength. Thicker steel also has greater resistance to “dings and dents” and punctures from heavy material or careless forktruck operation.

Just as important as the steel thickness however, is the hopper design and the way it is put together. Here at Iron Bull, we have done extensive research on other brands. We have taken the strong points of other self dumping hoppers and put them into a single package.

  • Wrap around lip on back corners
  • Welded reinforcing angle around top edge
  • Side of hopper extending down past the bottom and welded solid
  • Welded gussets on inside front corners

These features, put together in one single hopper, add up to a well built unit with great structural integrity

Choosing the Hopper Steel Thickness

Each self dumping hopper size has different steel thicknesses to choose from. The steel thickness of the hopper and the hopper base design determine the duty rating and rate capacity rating. The duty ratings are an important selection factor. For instance, if the material being put into the hopper are heavy chunks of hardwood or metal that will fall with some force, then, even if the weight of a full hopper is less than the weight capacity, a heavier duty hopper will be a better choice. The thicker steel in the heavier duty hopper will have greater “ding and dent”resistance which of course means less repairs and longer hopper life.

Capacity chart for our Self Dumping Hoppers

Note: each self dumping hopper within a particular series has the same height and length. Only the width varies to handle the different capacities. For instance, the Brahma Bull 4yd and the Brahma Bull 6yd are both 60”high and 90”long. Only the width is different. Use the following chart to help you choose the cubic size you need.

Mini Bull Series (H 26”x L 38”) / Economy Series (H 23.75”x L 38”)
The Mini Bull series has an ultra low profile and is short. The overall height is 26”and the length is 38”. Designed for narrow or tight areas. Available in 1/8 yd. increments.
Capacity: 1/8 (17”W), 1/4 (30”W), 3/8 (42”W) 
“Stretch”Series Capacity: 1/2 (57”W), 5/8 (70”W), 3/4, (84”W), 7/8 (98”W), 1yd. (111”W)
Baby Bull Series (H 29”x L 50”) / Economy Series (H 27”x L 48”)
The Baby Bull Series is also a low profile hopper. The overall height is 30” and the length is
50”. This series is very popular in the wood working industry. It is ideal for placing beside
your table saw, or, with the Bat-Wing™ Base, underneath your chop saw bench.
Capacity: 1/3 (25”W), 1/2 (37”W), 3/4 (55”W)
“Stretch”Series Capacity: 1 (73”W), 1 1/4 (90”W), 1 1/2yd. (102”W)
Junior Bull Series (H 36”x L 66”) / Economy Series (H 34”x L 66”)
The Junior Bull series is a medium height hopper. The overall height is 36”and the length is 66”.
Capacity: 3/4 (33”W), 1 (43”W), 1 1/4 (53”W), 1 1/2 (63”W)
“Stretch”Series Capacity: 1 3/4 (73”W), 2yd. (83”W)
Big Bull Series (H 43”x L 72”) / Economy Series (H 41.5”x L 72”)
The Big Bull series is our most popular. Overall height is 43”and the length is 72”. Be sure your
forklift has the correct capacity to handle these when full.
Capacity: 1 1/2 (46”W), 2 (58”W), 2 1/2 (72”W), 3 (86”W)
“Stretch”Series Capacity: 3 1/2 (100”W), 4 yd. (114”W)
Brahma Bull Series (H 63”x L 90”) / Economy Series (H 57”x L 90”)
The Brahma Bull series’overall height is 60”and the length is 90”. These hoppers hold lots of
material! Be sure your forklift has the correct capacity to handle these when full.
Capacity: 4 (62”W), 5 (76”W), 6 (90”W), 7 (104”W), 8 yd. (118”W)

Determining the right size for your operation

  1. Is the material large and bulky or tight and dense?
  2. Is height a limiting factor? Such as being used beside a table saw or placed under a conveyor.
  3. Is space at a premium? Such as between two pieces of equipment or equipment and a wall.
  4. Is the material long or short? 
  5. How often do I want to dump the hopper? The longer between dumping, then the larger the hopper needs to be.

Iron Bull makes 5 different series of self dumping hoppers. On the left is a description of each series. Within these 5 series, you can choose from a total of 30 different sizes from the Mini Bull to the Brahma Bull.
