Bulk Bag Suspender Frame

The optional Bulk Bag Suspender Frame allows the option of mounting larger, more economical bulk bags (“Super Sacks”) above Gruber’s Ground Hopper™ bulk solids conveyors.  Mounting large bulk bags reduce interruptions during the manufacturing process, and reduces labor costs normally associated with manual loading of a metering or feed hopper – particularly when compared to manual loading of smaller bulk material bags.  Automation of the bulk material handling system also results in a cleaner, safer working environment and more efficient manufacturing workflow.

  • Designed to mount on top of a Gruber Ground Hopper. Allows positioning of a super sack for drainage into the Ground Hopper.

  • Adjustable hook height (adjust the hooks to adjust the precise bulk bag height)

  • 4 way forklift entry for easy positioning of super sacks (pick up the frame from all four sides with integrated forklift channels.

  • Integral forklift channels for easy, safe lifting of entire unit via forklift.
  • Mounts on top of the Ground Hopper. The entire Bulk Bag Suspender frame can be lifted and lowered to the ground from the top of the Ground Hopper with a forklift if needed.

  • Rated for maximum 2500 lb (1133 kg) bulk bags


A number of other accessories are offered to further automate delivery and positioning of bulk solids – including powdered, granular or other bulk ingredients – such as calcium carbonate and other “difficult” materials. A forklift is generally used to load super sacks into position, but we also offer other material loading and positioning options, including Bulk Bag Gantries and Roller Conveyors to provide a number of possible material loading configurations.
