Learn More About Our Self-Dumping Hoppers

Self-dumping forklift hoppers are designed to allow forklifts and other equipment with fork attachments to dump materials and scrap without any additional motors or pulleys being needed.

There is a release latch on self-dumping trash hoppers which allow the hopper to be easily dumped and emptied.  When the load is dumped, the hopper closes on its own, and the release latch becomes locked.

Because they can be easily moved and dumped with a forklift, self-dumping hoppers are valuable in helping manufacturing plants catch, move, and discard scrap material.

This results in a safer workplace, cleaner shop floors, happier employees, and a more efficient manufacturing plant.

What Makes Iron Bull's Self Dumping Trash Hoppers Unique?

Here at Iron Bull, we have done extensive research on many kinds of hoppers available in today's market.

We understand that there are many factors that go into making a safe, durable, and truly efficient self-dumping hopper.  Some of these factors are the steel thickness, overall design, and the way the hopper is put together in the manufacturing process.

We have taken the strong points of other self-dumping dumpsters 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

One of the most important factors in a hopper's structural integrity 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.

Each forklift dump 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 fewer repairs and longer hopper life.

You can view our available steel thickness and sizes available for our self-dumping hoppers by looking at our section below entitled "Technical Specs - What size & toughness do you need?"

For in use, simply remove from hopper and magnetically stick it to the forktruck frame. To dump your trash hopper, just lock the thumb button and pull. After dumping, tilt the forktruck mast back and the hopper will automatically roll back into its locked position again.
