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™ can be paired with Erie Technical Systems  FlexMAX®, ValuMAX®, or a vibratory feeder to create a system to meet the specifications of each individual system.
