Manual and Automatic Bulk Bag Unloading Equipment

Erie Technical Systems UltiMAX™ Bulk Bag Unloaders, are designed to manually or automatically unload bulk bags. Our Bulk Bag Unloaders, also known as Bulk Bag Dischargers safely support bulk bags with a lifting frame.  The frame can be used with a forklift or an optional hoist and trolley system.  Once the bulk bag is in place, the operator can untie the bottom bag spout in a dust-tight environment.  Flow out of the bag can then be controlled either manually or automatically. The UltiMAX™ bulk bag unloader can be paired with Erie Technical Systems  FlexMAX® flexible screw conveyor, ValuMAX®, or a vibratory feeder to create a system to meet the specifications of each application.


Major Advantages of the UltiMAX™ Bulk Bag Unloader:

  • Heavy duty thick wall structural tubing construction
  • Heavy duty Support Frames can hold up to 5,000 pounds (2268 kg)
  • Modular frames sections allow hoists and discharge conveyors to be added in the field
  • Automatic or Manual operation
  • Dust-tight bag untie box
