SBB-HFF
The FIBC in this catalogue (code SBB) are devices suitable for discharging bags of di󰀨erent shapes and sizes.
They are manufactured from shot-blasted, painted steel; on request, they may be supplied in 304 stainless
steel, entirely or only the parts in contact with the product to prevent its contamination.
The numerous models and sizes of SBB available, together with the complete range of accessories make this
equipment suitable for use in virtually all applications and industrial sectors and with di󰀨erent types of FIBCs:
in fact, the hopper, which can also be supplied alone, is specially designed for optimising the ow of materials.
MACHINE CODE
- SBB
MACHINE TYPE
- FLEXIBLE INTERMEDIATE BULK CONTAINER UNLOADER
USE
- Emptying FIBCs of various sizes containing product in powder or granular form.
ADVANTAGES
- Equipment which can be assembled according to requirements.
- The model with hoist does not require the use of a forklift truck.
- The removable frame makes it possible to empty FIBCs 600 to 2000 mm in height.
- The operator is protected from falling FIBCs by the four posts of the frame.
- The FIBC valve can be accessed through the hatch.
- The pneumatic activators optimises emptying of FIBCs.
MODEL C:
HOPPER WITH FEET
- SBB HFF C
Thanks to its structure, there is plenty of space for using di󰀨erent systems for loading the FIBCs.
It comprises:
- a unloading hopper.
- supporting frame made of tubular elements having suitable size and thickness to ensure sturdiness and
solidity.
- cross with hooks for xing FIBC harness, lifting hooks and tubular elements for lift truck forks

SBB-HFF
MODEL S:
HOPPER WITH REMOVABLE FRAME
- SBB HFF S
Athough it is identical as regards design and use, the di󰀨erence lies in the size of the FIBCs which can be ac-
cepted.
These comprise:
- a unloading hopper.
- supporting tubular frame having size and thickness suitable to guarantee sturdiness and solidity.
- removable frame which makes it possible to adapt the Unloader for use with FIBCs of di󰀨erent heights.
- cross with hooks for xing FIBC harness, tubular elements for lift truck forks.
MODEL M:
FRAME WITH MONORAIL
- SBB HFF M
The special feature of this equipment lies in the fact that it does not require the use of a fork lift truck for ex-
ternal loading of FIBCs, as it is designed for use with its own hoist (not supplied) which makes it possible to
operate independently during the various phases.
The equipment comprises:
- a unloading hopper.
- a supporting frame made of suitably sized tubular elements thick enough to guarantee the required sturdi-
ness and solidity.
- a monorail for the hoist (hoist excluded)..
- cross with hooks for xing the FIBC harness, lifting hooks and tubular elements for using a lift truck if neces-
sary for handling FIBCs.
ACCESSORIES
- Hopper seal made of food- grade material.
Materials featuring poor owability do not ow out of the FIBC easily. It is therefore necessary to use pneumatic
activators. These devices act directly at the bottom of the FIBC, causing lifting and lowering of the opposite
corners to stimulate the ow of material compacted at the bottom.

SBB-HFF
The gradual movement of the activators makes the FIBC assume a “V” shape, to eliminate the deadlock points.
- Cutting device (ACCESSORIES).
It is used for cutting FIBCs without valves which cannot be recycled after emptying.
- Hose connector kit available in black or white food- grade rubber.
- Round or square ange for hopper.
- Raised feet for lifting the entire structure.
- Mechanical limit stop for signalling door open status (ACCESSORIES).
MOTOVIBRATOR
Important
The terms “equipment”, “FIBC Discharger” used in this manual refer to the same machine.
As components meant for installation in a plant, the equipment - not fully provided with safety means
- have to be considered “partly completed machinery”. Therefore, they do not bear an EC marking.
It is forbidden to start the equipment unless the machine/plant in which it is to be installed has been
declared compliant with the Directive 2006/42/EC and further modications.
In this regard, the installer must make provision for installing suitable personal and public protection devices to
avoid damage to objects and harm to persons in the event of breakage.
Before carrying out any operation, make sure the machine is in safety condition.
