MANUAL JUMBO BAG
UNLOADING SYSTEM
A hoist-assisted station for safe positioning and controlled emptying of FIBC jumbo bags into downstream conveying, dosing, mixing or process equipment, with optional paddle flow assistance.
HOW THE SYSTEM WORKS
STAGE
Position the filled FIBC on its pallet.
ATTACH
Connect four loops to the lifting cross.
LIFT
Raise the bag using the electric hoist.
POSITION
Traverse and align above the hopper.
DOCK
Secure and open the discharge spout.
UNLOAD
Paddles assist controlled material flow.
WHEN A MANUAL JUMBO BAG UNLOADER IS THE RIGHT CHOICE
PROCESS FIT
Moderate bag frequency
Practical for batch plants and lines with manual bag changeover.
Hoist loading
Allows bag handling from pallet level without relying on a forklift at discharge.
Variable powders
Paddles assist products that bridge, compact or remain in bag corners.
KEY ADVANTAGES
Improved safety
Lifting frame and bag cross reduce manual handling of suspended FIBCs.
Controlled discharge
Spout docking, outlet valve and downstream interlocks regulate flow.
Expandable design
Load cells, dust collection, lump breaker or conveyor can be integrated.
CONSTRUCTION & CONFIGURATION OPTIONS
STRUCTURE
Painted steel, SS304 or SS316L frame with certified SWL
LOADING
Integral electric hoist and trolley with FIBC lifting cross
FLOWASSISTANCE
Two-or four-paddle massage, vibration or bag
tensioning
SPOUT INTERFACE
Manual docking collar, clamp, iris or closure bars
OUTLET OPTIONS
Butterfly valve, rotary valve, feeder or conveyor
connection
PROTECTION
Hoist limits, overload, earthing and downstream interlocks
MANUAL JUMBO BAG UNLOADER OPERATING CONCEPТ
The filled FIBC is rigged at pallet level, lifted and traversed over the receiving hopper. The discharge spout is secured before opening, while massage paddles restore product flow toward the controlled downstream outlet.
CONTROLLED OPERATING SEQUENCE
STAGE
Bring the filled bag on a pallet
LIFT
Attach loops and raise the FIBC.
POSITION
Traverse above the hopper.
DOCK
Secure and open the bag spout
UNLOAD
Assist and control product flow.
CONTROL, PROTECTION & MAINTENANCE
Hoist permissive
Upper/lower limits and overload protection prevent unsafe lifting.
Bag confirmation
Bag loops and lifting cross are inspected before every lift.
Docking protection
The spout remains closed until it is secured to the inlet collar.
Discharge confirmation
Downstream equipment readiness is interlocked before opening.
Flow assistance
Paddles operate only when the bag is correctly supported and docked.
Cleaning access
Hopper, docking collar and outlet are accessible for inspection.
STANDARD RANGE & PRELIMINARY SIZING
Catalogue screening basis: single FIBC handled by integral hoist and trolley, manual loop attachment and spout opening, with optional paddle massage. Final design requires confirmed bag geometry and certified lifting duty.

CAPACITY CALCULATION BASIS
CLEAR HEIGHT CHECK
H = bag + loops + cross + hoist + lift
Include docking elevation and safe handling clearance
HOIST & STRUCTURE CHECK
SWL >= gross bag + lifting accessories
Apply certified design factors and dynamic allowance
WHAT CONTROLS THE FINAL SELECTION
FIBC geometry
Filled width, depth, height, loops, spout and gross mass.
Product behaviour
Bulk density, flowability, compaction, lumps
and moisture.
Lifting system
Hoist SWL, trolley travel, lifting cross and available headroom.
Flow assistance
Bag tension, two/four paddles, vibration and discharge rate.
Containment & outlet
Docking clamp, dust extraction, hopper and downstream device.
Safety & cleaning
Lifting compliance, access, earthing, guarding
and sanitation.
FINAL ENGINEERING CHECK
Confirm FIBC and product data
Approve layout and headroom
Select hoist and lifting cross
Design docking, hopper and paddles
Agree load test/FAТ criteria
