Product Description
The Single Loop FIBC Bag is purpose-built for operations where speed, simplicity, and crane compatibility take priority over forklift versatility. A single, centrally positioned lifting loop — reinforced with heavy-duty woven PP stitching rated to the full bag SWL — allows the bag to be attached to a crane hook or overhead hoist in a single movement and lifted with perfect balance, without the need to thread four separate loops onto forklift tines or crane spreader bars.
This simplicity makes single-loop bags the preferred choice for high-cycle crane operations in quarries, concrete plants, recycling facilities, and port handling environments where the speed of the lifting cycle directly affects throughput. Fewer connection points mean faster hook-up, faster unhook, and less handling time per lift — meaningful savings when multiplied across hundreds of lifts per shift.
Single Loop vs Standard 4-Loop FIBC
| Feature | Single Loop FIBC | Standard 4-Loop FIBC |
| Lifting method | Single crane hook / overhead hoist | Forklift tines (primary) |
| Connection speed | Fast — one hook in one movement | Slower — 4 loops onto 2 tines |
| Forklift compatible | Limited — not ideal for standard tines | Yes — primary use case |
| Crane compatible | Excellent — centred loop hangs straight | Requires spreader bar or 4-hook |
| Balance when lifted | Self-centring under hook | Depends on even loop engagement |
| Best environment | Crane-only operations, high cycle rates | Forklift-dominant facilities |
Why Choose This Bag?
- Single hook connection in one movement — fastest possible lifting cycle time for crane-based bulk handling
- Self-centring under hook — centralised loop geometry ensures the bag hangs straight without manual adjustment
- Less hardware per lift — no spreader bars, no 4-loop engagement; reduces crane attachment time significantly
- Compact loop profile when empty — single-loop bags stack more neatly than 4-loop bags in storage
- Available in all standard top/bottom configurations and with liner options for moisture-sensitive products
| 💡 BUYER TIP: For high-cycle crane operations, consider ordering single-loop bags with a bright-coloured loop (yellow or orange) that is visually distinct from the bag body. This allows crane operators to locate and hook the loop instantly from the cabin without descending to the bag level — measurably reducing cycle time and improving safety. |
Typical Applications Industries

- Ready-mix concrete plants loading dry aggregate into mixer feed hoppers
- Recycling facilities using crane-equipped vehicles for waste collection
- Grain silos and agricultural cooperatives using overhead hoists for bin filling

Frequently Asked Questions
Q1: Can a single loop FIBC bag be used with a forklift?
Single loop bags are designed primarily for crane hook and overhead hoist operations. While it is physically possible to thread a single loop over one forklift tine, this creates an unbalanced lift and is not a recommended practice. If your operation uses both cranes and forklifts, consider a 4-corner loop bag for forklift primary use, or a cross-corner loop bag which is compatible with both crane and forklift operations.
Q2: What is the weight limit for a single loop FIBC bag?
Our standard single loop bags are rated from 500 kg to 1,000 kg SWL. The single loop construction concentrates the lifting load at one point, which limits the practical SWL compared to 4-loop bags where the load is distributed across four attachment points.
Q3: Is a single loop bag suitable for discharging material directly into a hopper or vessel?
Yes — in fact, this is one of the most common applications. The crane hook can position the bag directly over a hopper opening, the bag is lowered into position, and the discharge spout (if specified) is opened for gravity discharge. The single-hook connection makes it easy to lower and raise the bag precisely without the need to manage multiple connection points.
Q4: How do you ensure the single loop can handle the full bag SWL safely?
The loop is manufactured from the same high-tenacity woven PP fabric as the bag body, formed into multiple plies and stitched with reinforced cross-stitching patterns at all attachment points. Loop construction is tested to ISO 21898 loop break strength requirements — the loop must withstand a minimum of 6× the bag SWL for single-use (5:1 SF bags) before failure.
