Our T6 bulk bag unloader is a fully self-contained unloading station with bulk bag lifter for dust-free and controllable bulk bag emptying.
The T6 has an integral “I” beam and hoist for lifting and loading bags into the unloader and is directly connected to an enclosed conveyor for direct transfer of product to process machinery. Bulk bags may be brought to the unloader by pallet truck and stored ready for lifting without the need for forklift assistance. Full dust control features are incorporated.
Like all of our bulk bag unloaders, the T6 with integral bag lifter can be provided with a multitude of options such as loss-in-weight batch controls, extended gantry frame & hoist for multi-bag processing, bag dump door, hygienic liner clamp, liner remover, bag massagers to aid material flow, and more. Of course, custom designs are always available.

HOW IT WORKS
The T6 Integral Hoist Bulk Bag Unloader is used when bulk bags must be loaded and unloaded into the frame without the use of a forklift.
This bulk bag unloader is made of heavy-duty square tubing framework with cross members, an upper frame and an “I” beam for the 2-ton electric hoist with trolley for lifting the bulk bag into the support dish. The bulk bag provides the seal against the support dish for a dust free seal. The heavy-duty 4 in./ 100 mm square steel tube frame is welded directly to the support dish. The T6 Bulk Bag Unloader can incorporate a number of design options in order to provide maximum versatility & ease of use. The discharge of the chute is custom made to fit the application.
Process Steps
STEP 1: A bulk bag of product is fitted with the Bag Lifting Frame.
STEP 2: The operator lifts the bulk bag into place with the integral hoist & trolley.
STEP 3: With the weight of the bag safely supported by the Support Dish, the operator can now freely & safely access the bottom spout of the bag.
STEP 4: The operator opens the access door & unties the bag spout.
MODELS & SPECIFICATIONS
The T6 bulk bag unloader with integral hoist for built-in lifting is one of several designs we offer. Features of our various models are typically mixed and matched to accommodate specific application needs. And, of course, we regularly build custom designs. Here is a list of our basic models. Your Spiroflow Sales Engineer will evaluate your needs and recommend the best configuration to do the job.
| MODEL | DESCRIPTION |
|---|---|
| T1 | Entry level basic frame design available in the UK & Europe |
| T2 | For unloading by volume |
| T3 | For loss-in-weight unloading |
| T4 | For unloading single trip bags |
| T5 | For discharging in low headroom areas |
| T6 | Includes an integral hoist when a forklift truck is not available to load/unload bags into/out of the bulk bag unloader |
| T7 | For unloading multiple types of containers including bulk bags, rigid bins & boxes/octabins |
| T8 | For USDA/3A applications |
| T9-CV | For total containment when handling volatile or explosive materials |
| T10 & T11 | For pharmaceutical applications |
| Flo Style | Flo Style unloaders, from our purchase of Control & Metering, have a 40º or 60º sloped hopper that supports & shapes the bag for ease of discharge. Pulse vibration, instead of massage paddles, is used to induce material flow. The bag is kept elongated via gravity throughout discharge. It can be configured as a T2, T3, T4 or T6. |

YOUR UNLOADING REQUIREMENTS
Before purchasing a bulk bag unloader always ask these key questions:
- Will the bulk bag unloader accept varying bag sizes?
- Will the bulk bag unloader handle poor flowing products?
- Is there a forklift available or is an integral hoist needed?
- Does the bulk bag unloader provide a controlled flow when the spout is opened?
- Does the bulk bag unloader have a bag tensioning device to ensure all product is discharged?
- Is discharge of the bag contents required by weight or by volume?
- Is there provision for restraining and/or removing the inner liner?
- Is an integral take-off conveyor required?
- Is there a height restriction?
- Is there a way to empty small bags in case the bulk bag supply of material is interrupted?
- Does your plant require a hygienic bulk bag unloader or USDA/FDA approved equipment?
- What dust control features are incorporated into the bulk bag unloader?
- When untying the bag spout
- While the product is being discharged
- When the inner liner is being removed
- When the bag is removed and folded for disposal
- Is the product or environment hazardous?
- Is static grounding and monitoring required?
